This is really a good start!
👍Thanks!
Wow! wow!!!!
I actually had this in mind. Also alternative for auto or motorcycle. Par with carbon fibre.
possible to make excellent composites cheaply.
Lovely🤩🤩🤩🤩
👍
Rly good work on improoving something like the sea container. Now with water and bug resistant bamboo its rlygreat. It will improve the world, but it will allways be unseen and unheard, staying in the shadows.
Thanks 👍. Let us popularize such environmentally friendly solution.
Great
👍
Bamboo keep coming back and win again
True👍
I think it would have been more durable if you had also applied the vacuum process. The vacuum process both eliminates air bubbles and allows the epoxy to penetrate into the bamboo.(Of course, I have no idea how much bamboo absorbs epoxy, for lamination with epoxy, especially resin-free tree species are selected and treated with epoxy.)
You are right, vacuum could be tried. Our specimen was quite large which prevented us from using vacuum. I also do not know if vacuum can help absorb more epoxy inside the bamboo fibres.
This is a worthwhile project so I have some questions:
If the bamboo was not cut into strips would you save weight, albeit at ther expense of volume and density?
Would you also not save a great deal of time by not stripping the bamboo, or is this a cheap and common process?
I appreciate you would use more epoxy but would you still need to degrease the bamboo if it was not cut into strips?
Thank you.
👍Thanks a lot for your questions.
1. In making any composite, volume percentage of the fibre is decided. Weight saving is compared to alternative materials. In this project, the goal was to replace apilong board. At the end of the project we were able to save weight because the bamboo-epoxy composite was stronger than apilong board. Hence, even if the new material is not lighter than the previous materials, if it gives you better strength for the same weight then there is weight saving.
2. This was a student project and hence the whole process was not yet optimized. One should study and find out which process will be better and cost effective.
3. Strips or fibre of bamboo is necessary to make it a board of this composite. The bamboo itself (without epoxy) could not be used. De-greasing will be necessary to remove the lignin part of wood and use only the cellulose fibre. It needs to be studied more.
It is a nice project.
I have a question
1)what are the tests that can be performed on this composite material
You should start with some of the mechanical tests such as tensile test, impact test and may be fatigue test.
I think , it is really a nice project . I have some questions to ask?
1. How much epoxy plus hardener you are pouring? Is there any measurement and formula.
2. How many layers of bamboo you are placing?
3. Mould size and material of the mold?
1. Amount of epoxy will depend upon the volume % of fibre you want to fill in this composite. Normal we need more than 50 vol% of fibre or more. Amount of hardener is provided by the supplier data. Often it is 2 part epoxy and 1 part hardener.
2. As much as you can pack. You will find that it is not easy to pack high vol% of fibre.
3. Mould size (cavity size) was 14 inch x 14 inch x 1.18 Inch (depth).
Thanks for asking 👍👍 Please share this video with your friends. 👍👍
Hello sir, First of all, I want to say it is a good project. My query is what type of bamboo and what is the dimension of the strips and the mould size?
Bamboo strip size was 12 inch x 0.47 inch x 0.08 inch (thickness). Bamboo type is Bambusa. Mould size (cavity size) was 14 inch x 14 inch x 1.18 Inch (depth). 👍
@@engineeringmaterials-tribo5142 Thank so much for your kind reply.
Hey, nice work
Can this project be done at home?
Can you please tell me the cost of the project?
Main cost is the epoxy. It depends on the grade of epoxy. To start you can use the normal epoxy glue, araldite, that you can buy in a hardware shop.👍
Which is the cheap and best adhesive to be used with bamboo?
Epoxy can work fine.✔
I’m really interested, can you be a consultant in developing and producing this material
You can contact me if you need any related information. Thanks👍
Please which kind of resin did you use? what is the name of the Resin used. Thanks
Epicote 1006 system, supplied by Wee Tee Tong Chemicals Ptr Ltd. Singapore.
You need finer fibers, because absorption of epoxy into whole bamboo pieces will be low and there will be too much epoxy outside the bamboo strips which creates brittleness and unnecessary weight.
True. This was a student project. In real practice bamboo fibres must be prepared as very fine fibres for good adhesion with epoxy. Volume % of fibre should be nearly 70% .👍
I was thinking, how you can actually make a bamboo sheet. Then cure it with epoxy, there are plenty of spaces in bet the strips. So yeah converting the strip to sheets would actually give a better resulting product
you are right👍
I need your presentation sir. We have taken this topic as our final year project. SO, please up a video of exact datas for resin, Mound design or can I send any email sir?
All information has been provided. Some are discussed in the comments. I do not have any more data now as the project was carried out many years back.✔👍
@@engineeringmaterials-tribo5142 sir, can u tell what is the mould Size and bamboo strips dimension and no of bamboo strips to be placed.
Is there any part worked out through ansys ? Please tell sir what are the calculations we need to do before anything working out practically
I am very sorry I do not have anything more than what I have shown in the video. Please work by yourself to do the analysis.
Can use polyester resin?
Yes, I think so. 👍✔
What type of epoxy and hardner you have taken sir
Epicote 1006 System with the hardener as provided by the supplier.✔👍
Pineapple fiber unidirectional mat with epoxy coating will it give good fracture strain?
You meant fracture strength, I think. All depends upon the fibre strength. Have you checked?✔
@@engineeringmaterials-tribo5142 i just doing this depending upon the research paper
@@ajinkyamule2684 👍
@@engineeringmaterials-tribo5142 how much pressure should apply and for how much time after putting epoxy on fiber or bambo
@@ajinkyamule2684 You can check in my video. It should be high constant pressure during curing.
Where can I get bamboo raw fibers , sir , I need raw bamboo fibers as well bamboo non woven fabric , where can I buy it , please share details
The project was done many years ago. I do not have the contacts. Please try to find from the internet or other sources. The bamboo sticks used in this project was locally sourced and prepared by the students of NUS. 👍
Hello sir. I want to ask more questions on this project. We are doing similar project . SO, if you send any material, I think ,it will be very very useful for us👍
most information are in the video or answered in the comment section. Kindly check. Thanks👍
@@engineeringmaterials-tribo5142 Even though the questions were answered, I have lot of questions in my mind. So, please tell how do I contact you
Im doing same for pineapple fiber unidirectional mat .so what should be the concentration of epoxy resins and hardner
Generally, you need to keep volume % of fibre above 60.
@@engineeringmaterials-tribo5142 suggest me company which made epoxy resin..which one should I take for composite material.? Which is better for curing at room temperature
@@ajinkyamule2684 For a start any epoxy will do. One comes with the name Araldite epoxy (AY103) and hardener HY991. Once the hardener is mixed with epoxy, curing will start at room temperature but you may need to heat for better results. You can find one which is completely room temperature curing epoxy.👍
@@engineeringmaterials-tribo5142 thank you so much
Please reply
sir can you suggest me some good epoxy nd hardener for unidirectional continuous bamboo fiber.. or share some link where i can refer best epoxy resin for my project work.
As a start you should buy normal epoxy that are available in the market. The supplier will also sell hardener. For research work you should buy from Sigma Aldrich. This can be expensive. All depends upon your application aim.
@@engineeringmaterials-tribo5142 sir what is the future scope for this project can you share.if u have published any paper related to this work you can share the link here.. here you are using bamboo with only one concentration of NaOH sol..we can use different conc of NaOH and check how the strength varies.
We can take different volume fraction of bamboo strip and check the strength. And analytically also we can show using Rule of Mixture, Halpin Tsai etc using different volume fraction of fiber.
Last one- u have taken bamboo strip of large dimension. If bamboo strip is made more fine then i think we will get some good strength.
@@parthapratimbarman7551 You are right in those ideas and should definitely try them. Our project finished at that time because the students graduated.
@@engineeringmaterials-tribo5142 and sir i just want to know two more things
1. have you published any paper related to this work?? Because I am doing some work similar to this for my M.tech final project..If u have published then you can share with me .
2. What is the specimen dimension for tensile strength and flexural strength u have considered for this work..like ASTM (______) ..u can simply specify the code, remaining dimensions I will get from the internet..
@@parthapratimbarman7551 I have not published this work. For tensile test of composites you can follow this th-cam.com/video/Sm7s0ygruww/w-d-xo.html
You need to find ASTM standard for the three point bending.
How can I create bi directional composite for short bamboo fiber typical length is around 4-8mm
By laying them at random on 2D. Actually we tried in the video by laying the fibres in two direction normal to each other. Please note that fibres can much thinner than the ones we used in our work.
@@engineeringmaterials-tribo5142 yes sir difficult is how very short and thin fibers can be arranged?
do you have paper related to this work (material by company)
sorry, no.
Did you consider cost analysis
cost analysis was done for the bamboo- epoxy composite and it came around SGD45 per square feet. It is possible to reduce the cost by choosing cheaper grade of epoxy without actually compromising on the quality.✔
@@engineeringmaterials-tribo5142 so probably expensive than traditional container by percentage margin
Bro do you have ppt or PowerPoint of this project?
I wish I could but because of copyrights I will not be able to share the ppt. These things can be done by any finite element software you know or may be you can learn one. The experimental parts are quite clear in the video. Thank you for your interest. 👍✔
@@engineeringmaterials-tribo5142 I have a presentation of this project this month so was asking
Hello sir, how can I contact you? I am a polymer technology student who is currently doing my final year project in bamboo/pp composite.
you may send by your query here. Thanks
@@engineeringmaterials-tribo5142 Thank you for responding. Do you perhaps have published any journals regarding the bamboo composite? I want to make them as references to my final year project.
@@fatinnajihah1567 I do not have a journal paper in this field. However, you can provide this TH-cam link as reference.
@@fatinnajihah1567 No journal paper for this composite. We did make some other composites. You can look up in Google scholars (scholar.google.co.in/citations?user=aybvKicAAAAJ&hl=en)
What was the cost of the project?
The cost of making this composite was calculated as approximately 45 Singapore dollars per square feet of the composite.✔👍
So the composite would be stronger an better.
However. unless its made by mass production, it would take too long an costly to produce, for commercial use!
You are right. Cost is the main disadvantage now in the application of composites. Fortunately, short-fibre composites can be produced at reduced cost. So, depending on the level of application, one can decide to use long fibre or short fibre composites.
I appreciate your comment. 👍
Epoxy is essentially plastic right? ..so we're just continuing the use of plastic and locking the natural product from degrading?
Epoxy is a plastic. Woods are pretty durable if protected against water and termites etc. So, this method of locking them inside a plastic can help to prolong the life of the wood. Of course, in this project, the objective was to come up with a light and strong material to replace another wood which is less abundant. Bamboo is quite abundant and is a very fast growing plant. The amount of epoxy used in such composites can be very small if the volume of percentage of the fibre is increased up to 70 or more.
Looks like a pretty expensive process, as epoxy is not cheap!
Epoxies are of many types and the cost depends on this. The regular epoxy which is used as common adhesives (araldite) are quite cheap. Some types which are used as adhesives in airplane manufacturing etc are quite expensive. Industrial method of making composites can be made better to reduce cost. This one was a student project and hence cost was not looked into so much. For composites, fibre and manufacturing costs are the main issues.
Thaks a lot man.. Because this idea of want... So please kindly give an a details information is it possible
All information are there in the video.👍

Sir please provide me synopsis and PPT for reference
Please sir
Sorry, this is an old work and I do not have the thesis with me.
I am making bamboo pulp and hand made paper at home
wow!👍. Please share how it went.
Secondly the plywood may damage by the moisture where as the appoxi composites may resist the moisture also
It is true. However, this application is for dry environment on the floor and inside the container.👍
Too expensive..
Thanks for your comment. It was an experiment. There are many ways to reduce the cost if the experiment is successful.👍
