Rubber and Epoxy..


Recommended Posts

Ive been hearing about a rubber that is treated for bonding (?) and used under fiberglass in high impact areas to reduce delam (Ski edges, golf club shafts, sports racquets etc)

It makes sense, but there also happens to be only one german company making the stuff called 'VDS' rubber and they have a minimum order of something like a kilometre.

 

Has anyone had experience or trialled any techniques at doing something similar? WOuld be super keen to hear.

Even epoxying to rubber in general - sounds intuitively like a no go but Ive never actually tried it.

 

 

Ta Ben.

Think I may have used the product you're talking about a few years back. We had it on our cars for the leading edges of the front wings and suspension package, mainly for the sandy races like the Bahrain GP etc. We had massive issues with sand abrasion damage and essentially parts of the car wearing away as it went through the race distance. Pretty sure you can buy it in a 2 part liquid mix that can be cast and set. Haven't seen it used as a core product though. Better to use a solid laminate core replacement in most applications.

Nuplex and Hi Mod have a rubberised epoxy resin that can be used in a 'thick' form but it isn't a rubber sheet. Very strong and used to glue carbon bits together amongst other things.

Not sure if that's what you are thinking.

I use a marine waterproof 2 part contact bostik product nearly every day for gluing neoprene to f/g or alloy. Bostik 2402 or 2405 with a desmodeur cross linking agent. Ridiculously strong, we build and repair and build ribs with it, boats that is I'm not a doctor.

Thanks for the info guys. The difficult thing is it has to go in a standard epoxy carbon wet layup, and is all pressed at the same time so I cant use a specialist glue. The HPR resin is definitely the go.. But the bank budget is tight!

 

It is for helping the fibreglass stick to a steel ski edge, and maybe absorbing energy from that bond to reduce the chance of delam.

 

Wheels: facebook.com/DEVOboardshapers , but I will put that into a new thread. Its a project I set up to write off some of the engineering hours for Mech Eng degree at Auckland Uni. So far have been building longboard skate decks, but just starting on the new challenge of snow skis for winter!
