Why carbon frame damage needn't mean the scrapheap for your bike

http://ift.tt/1t0oU58

Carbon fibre is a bit of a wonder material in the cycling world, it’s lightweight, and depending on the layup can be tuned to be stiff on one axis, and noodly on another. It can also be moulded into radical shapes to cheat the wind.

Unfortunately for such a cycling industry mainstay, the high-modulus carbon used in bike frames and components is quite brittle, despite its high tensile strength. Designed to handle forces on a certain axis, a sharp impact from a different direction, say from a crash, has the potential to cause serious damage.

Take a look through any secondhand bike site and you’ll find pages of late model carbon frames with cracks, broken seatstays, and crushed carbon parts. Fortunately though, if you’ve got a broken bike all may not be lost – because quite a lot of damaged carbon fibre can be repaired.
