Simple and straight explanation, loved the way you created this content. Happy that i came across your content.😇
@raja bhupalan. Firt of all tank ou very much for your comment. It is one of the most beautiful comments received and this encourages me enormously to continue. I thank you, and as well to all my other subscribers who appreciate the content on my channel. You bring me so much satisfaction and confidence!!!
Good video. I am a Vinyl Ester Resin fanatic. I think the benefit of using Vinyl Ester Resin vs. Polyester Resin is best illustrated at the point of failure. Vinyl Ester resin is far superior to polyester and will "Flex" or "Bend" much more the Polyester before the laminate will fracture. This can be illustrated using strips and bending until the strip fractures. All and all, good content!
@Vernese Customs. First of all, thank you very much for your comment. I am very happy to add that we have the same passion for resin and fiberglass. In the future I will make a more professional test stand to be able to process more samples and to have more accurate results. Thank you very much for your support. This helps me and motivates me to keep posting more videos!
Very informative video sir. No need for me to experiment in my fins. Already go this one and I really appreciate it

This encourages me and motivates me a lot to continue!!! if you haven't already, don't forget to subscribe to the channel!!!
Thanks for sharing ! Love your test set up for bending, eye opener! . I am making test for a thin leeboard for my sailing kayak. My plan is to use 1/8 inch plywood and laminate it . I’ll then shape to a NACA form. I have leftover fiberglass and carbon fiber from other projects so there I go
@Javier Correa. First of all, thank you very much for your comment!!! I am very glad to hear that you liked the test. I plan to prepare more tests, but I haven't found the necessary time yet, being involved in a project that I hope will be finished soon. I would like to test some fiberglass cubes under the hydraulic force of a press. This way I can see the compression resistance of each type of glass fiber.Thank you very much for your comment though. This encourages me a lot to continue, knowing that my work is appreciated!
A very very interesting and informative tutorial. Thank you so much.
@norber yamson. First of all, thank you very much for your comment. In the new episode that will appear on September 6, I will continue testing these samples to the breaking point. So stay tune!!!
Very interesting comparison. I'm planning on making a new hatch from my boat, with centre layers made from coremat. I think it gets more stiffness if you have layer(s) of glass on both the top and bottom surfaces, where one is under tension, and the other under compression, By increasing the distance between the two layers of glass, you gain greater torsional stiffness than by having them close together, it would have been interesting to see the strength of coremat and 2 layers of glass.
@jpwilliamsj. First of all, thank you for your input, and I genuinely appreciate your attention to detail. You're absolutely right about the placement of Coremat between the layers of CSM - it's crucial for maintaining structural integrity. If you're interested, I have an older video on my channel where I delve into the specifics of using Coremat.
I've already prepared the samples for the upcoming episodes and will be featuring a laminate with two outer layers of CSM and Coremat between them. I'm also working on enhancing the test stand to ensure more consistent data. It's an exciting project, and I'm eager to share the results with you. Unfortunately, the editing process takes a bit of time, so please bear with me; the video will be up in approximately three weeks. Additionally, it might be beneficial to consider incorporating reinforcement through thoughtful design, such as the inclusion of longitudinal ribs. This could further enhance the overall structural integrity of the hatch. If you found my response valuable, I would greatly appreciate it if you could consider subscribing to the channel, if you haven't already. Your support means a lot to me, and it serves as a significant source of motivation to keep creating content. Thank you in advance!
very good video. thank you
@twins twins. First of all, thank you very much for your comment. In the new episode that will appear on September 6, I will continue testing these samples to the breaking point. So stay tune and thank you very much for your support. This motivates me enormously to continue.
@@PAFixandCrafts ok, waiting)
thank you so much!
@Geo clips. First of all, thank you very much for your comment! In the future I will perform more tests and create a much more professional test stand. I will also try to show types of reinforcement and their importance.Thanks again for your support! People like you motivate me and give me satisfaction that my work is appreciated!
I had a damaged frame rail on my car that I pound out straight and completely filled the damaged area (plus an additional 3 inches past both ends) with chopped fiberglass and epoxy resin. I'm hoping that will be nice and strong for a long time. It's a solid mass of epoxy and chopped fiberglass that's 3.5 inches tall, 4 inches wide, and 10 inches long.
@Pendragon501. First of all, thank you very much for your comment!!! I'd like to extend my apologies for the delayed response. Regarding the repair you mentioned, I genuinely see no reason why it wouldn't hold up well, especially considering the support material and level of reinforcement. Given the circumstances, it should endure without any issues. If you found my video to be of assistance, I'd greatly appreciate it if you consider subscribing to the channel if you haven't already. Your support serves as a significant motivator for me to continue creating and sharing new content.
Hello when doing this test you need to consider fiber orientation which will strongly influence tests.
@Dave Demchak. Of course, this aspect is extremely important. But in my experiment, all the samples had the sewn fiberglass oriented in the same direction (0, 45 and 90 degrees). RW in two directions (0 and 90 degrees). Regarding the coremat and the CSM, this theory does not apply because the coremat has the same rigidity no matter how it is placed and the CSM takes 50% of the force distribution in all directions. Only the resin used is different in this case. But there are many other factors that can influence the quality of the laminate, such as the percentage of catalyst, ambient temperature, relative humidity, the amount of styrene in the resin, the viscosity of the resin, etc. If you haven't already, don't forget to subscribe to the channel. We share the same passion from what I can see and your support means a lot to me.
Do you have a test with epoxy resin?
@moogdoog. First of all, thank you very much for your comment! Unfortunately, I didn't do a test with epoxy resin because I have a few projects where I use this resin. In general, I use a lot of polyester and vinylester, but I will take it into consideration, maybe I will do a test in the future. But what is very important to know is the fact that the glass fiber used in combination with epoxy is slightly different from the one used in combination with polyester. Fiberglass is the same. The only difference is the glue that holds the fibers together. In the case of glass fiber for polyester, this adhesive dissolves in styrene. Styrene, which is a component of polyester resin and helps the absorption of the resin by the glass fiber. In the case of epoxy resin, a powder is used to keep the glass fibers glued and this helps the absorption of the resin by the glass fiber.Hoping that my answer was helpful, don't forget to subscribe to the channel if you haven't done so yet. This helps me a lot to continue. And if you have any questions, don't hesitate to write to me.
Have you tried this type of test using S-glass?
@tomcop668. First of all, thank you very much for your comment!!! Unfortunately, I was unable to conduct the test due to the unavailability of S fiberglass in my current inventory. However, recognizing the importance of such a comparison, I am considering the inclusion of S fiberglass in future testing initiatives. Your understanding and patience as I work towards enhancing our testing capabilities are greatly appreciated. It is known that S-Glass, or "structural glass," is known for its high tensile strength. It is stronger than E-Glass but less flexible. E-Glass is more flexible and has a lower price. E-Glass is widely used in a variety of applications, including boat building, automotive components, and construction. It is a versatile and cost-effective option for many industries. Instead, I see S-Glass more for special applications. If you found value in my response, I would be sincerely grateful if you considered subscribing to the channel, if you haven't already. Your subscription serves as a motivating force, inspiring me to create and share more content in the future. Your support is immensely appreciated, and I look forward to bringing you more informative and engaging videos.
So can someone order a sheet of fiberglass with a coat of resin?
@Escanor. First of all thank you very much for your comment!!! If I understood your question correctly, you need a fiberglass plate. And depending on the size and the region where you live, I can help you, but my question is what type of fiberglass do you need. Or if you can describe to me the type of application you want to use this plate for, maybe I can recommend the right fiberglass. Here I mean the structure and density that makes a single layer behave totally differently. If you want to help me too, don't forget to subscribe to the channel. It is very important for me.
I need the sample
@PTinvest. First of all thank you very much for your comment!!! I would love to help you with these samples, but if you are not from Romania or the immediate vicinity of Bucharest, I don't know how to proceed with their transport.
