Carson P.I.M.F. process

Carson’s P.I.M.F. (post-resin impregnation of multi-structure fibre process) bonds raw glass fibre and/or carbon fibre yarn directly onto the mandrel.

It uses a wrap of multi-stranded thread nylon/polyester/ glass fibre/carbon fibre/Kevlar to secure the raw material yarn over the mandrel, which is then immersed in a tank for pressurisation and decompression impregnation before curing in a low temperature oven.

This is an improvement over the existing rolling system which uses a resin impregnated, high cost fibre cloth. This produces excess layers inside the blank after rolling because the cloth is already hardened to some degree. Air bubbles in between the layers makes the blank weaker.
