Hi all,
I am undertaking an R&D project to reinforce a curved wood surface with Kevlar. It will need a resin surface of some sort that can withstand regular strikes against a metal edge.
The kevlar will be reasonable secure against the surface, but the resin will need to both bond and seal the surface.
The clarity of the finish is not critical and ideally, the surface should be machinable or at least able to be smoothed with sandpaper or varying grit.
In terms of application, I was hoping not to have to cast, but i'm not sure as to what finish can be achieved with a brush.

I can't give too many specifics due to IP, sorry. All ideas greatly appreciated.

Thanks in advance, Ric

Its hard to recommend anything without knowing the application. Based off your description, I would say what you are looking for does not exist, and you will have to compromise somewhere or look to redesign.

Resins are not great at taking regular impacts from a metal edge, but then it also depends on how hard those impacts are. Resins made for laminating reinforcement like Kevlar are typically quite brittle, and wont last long taking regular impacts. Polyurethane rubbers are likely to be the most resilient, but they would need to be cast and do not have fantastic bonding properties, so no good for your Kevlar. 

A flexible epoxy like Ex's EF80 might be the most suitable, but it still isnt going to take impacts superbly well - it is flexible rather than soft.


Thanks @Hanaldo, I think I was slowly coming to a similar conclusion. I will try EF80 first as this may offer what I need. The application has a somwhat throwaway aspect and the main purpose of the kevlar is to prolong the life of the wood. The hope is to try and make a cost effective compromise between durability and replacement time.
