Nice adhesion my dude
what if we used the single hyposol adhesive? does the mixture increases the bond strength?
"test the bond by pulling or twisting" .. With the diameter of tube and surface area used in the joint, this assembly should hold >1000 Nm torsion and >>>10kN tensile before failing. The tubes will fail long before the joint fails. Good luck pulling that apart by hand ^_^
When joining carbon tubes end to end, do I just order another tube with it’s OD to match the ID of the other 2 tubes? Or can I order that insert tube ?
Can I use 150 grit sandpaper to bond two composite plates? Another question is, do you use acetone to prepare the composite surface?
I have a carbon fiber strut tower bar that has come apart where the aluminum mount goes inside of it. What is the best product to bond the carbon back to the aluminum??
Carbon fiber and aluminum attack each other galvanically. If the part wasn't built with an insulator between them, like nylon or fiberglass, any repair will be temporary at best.
Why didn't he protect the carbon fiber tube end with a masking tape too? That would then help him out not to spend much time and efforts wiping off the excesive amount of adhesive. Another thing is that while wiping it off from the carbon fiber tube he could possiby scratch the end off as the the adhesive containts glass beads in it.

Thanks for this video! Any specific differences when bonding to aluminum? Specifically 6061 to standard 90 degree offset tube?
Application is a 60cm push Rod in a cantilevered suspension, so outside of external impact, only tension and compression loads
Reason for asking is different thermal expansion properties- use case is all from 10 To 35 Celsius, but asking as a form of sanity check
10 to 35°C isn't a large differential in temperature so you shouldn't see very much growth. However, there are adhesives that are better when bonding dissimilar materials like aluminum and carbon fiber. These are usually toughened adhesives that are a bit more flexible and less brittle.
@@RockWestComposites Hi, what adhesive would you recommend for bonding a tight fitting aluminium shaft into a carbon fibre tube for a bicycle. part will be under axial tension and radial compression will experience a lot of vibration from road in use. Many thanks

I scroll down to say the same thing, and this is the first comment I see hahaha!
I was going to say they sound like Afrotech Mods

Which adhesive is recommended to glue aluminum parts in the carbon fiber tube ?
Marcelo, you will want to use a two part adhesive like a 3M or Loctite as well as a glass bond bead to prevent any corrosion. Give us a call at 801-566-3402 and we can walk you through the process.
do you have an email?
I'm wondering if adhesive bonding can be used in an aluminum insert to carbon fibre tube fitment that will see high load, impacts and stress. The application is for a mountain bike swing arm.....??
Adhesive will work in that application as long as the bond is designed correctly. If you have any questions give our office a call at 801-566-3402 and we can walk you through the process.
Look up the product Alodine and follow the instructions. The key to bonding Aluminum is cleaning the surface and bonding before any oxidization can set back in.
how big is the recommended gap between those two pipes? Could you provide a percentage? THANKS
Faruk, we would typically recommend a gap of around 0.008” to 0.013”.
How long should the overlap be in relation to the diameter? There must be a formula but I can’t find it online.
A good basic rule is 1- 1.5 times the diameter of the tube. If you have a thin wall, you would want something a bit longer.
@@RockWestComposites Many thanks for your response. I will keep that rule of thumb in mind.
Do the adhesives protect the surface of the steel of oxidation?
In a sense but that isn't the direct goal.
Cool
Any tips on how might go about making a carbon fiber flange to bond to carbon fiber tube?
For making flanges, you may have to make a mold first, fabricate the flange, then bond it to the existing tube. The odd shape of a flange can be tricky to layup, but it's not impossible.
Can this process be done inserting a carbon fibre tube into an aluminium one ?
Yes, absolutely! You just need to ensure the diameters are suitable and able to slip fit for bonding.

you should tape both tube
at 3.22...what is that?like a dust.can i know what is that?
That is Bond Line Control beads. These are specific diameter glass beads that help maintain a constant bond line thickness for better bonds.

130feet a. What the cast
And mixes on cardboard ??
Great observation, but with the allowable minor variances in stoichiometric epoxy mix ratios, especially with tube dispensed adhesives, The minor amount of material absorbed into the cardboard (of both part A and part B), will have an imperceptible affect on the final cure properties of the adhesive.
How cold is safe?
Hey there Marc, good question. One example would be an industry standard DP420 from 3M.

Cool video but the narration bot is painful
Ha, it's not a bot at all, he is a real human , I have met him. Just like I am not a bot. Or am I?
whoz teaching these people that they have to OVER annunciate..sounds like hes sucking on the mic.its really annoying
It's what we get for hiring bird man.
