      Hi Geoff,         Before saying anything about the details, I’d like to ask a question: is the original structure glass fibre? That looks like a piece of (never been wetted) glass cloth hanging out there. If it is GF you could mend it with GF. If I understand the way the tongue works, there is quite a lot of area for it to bear on in normal flight, and there doesn’t seen to be much point in making the repair super strong (aka heavy).        The reason I ask is because polyester resin is often used in conjunction with GF, and the epoxy resin usually used with CF and Kevlar may not be compatible with it. Your repair may easily detach from the original structure in the event of another unfortunate incident.        Cheers        John

      Hi Geoff I wont pretend to know the best way of repairing it but just thought I would point out that carbon and Kevlar are two very different materials with very different properties and uses. Kevlar gives very little rigidity/stiffness but it gives enormous impact resistance. Its normally used with another fabric that offers the rigidity/stiffness, such as when used on kayaks. Kevlar is sandwiched between layers of fibreglass which gives  it some stiffness and the Kevlar gives it massive impact resistance against rocks.  Carbon will give the stiffness you require so if it was me I would use a mixture of both but some may say it would be overkill. Just keep the carbon away from any aerials.  Brett
