Abstract

A pliable tackified tow comprises a plurality of fibers having a tackifier present at about 1-15 per cent by weight uniformly distributed among the fibers. The tackifier is a solid material which has been fractured through fiber displacement such, as by physical bending, to produce a fiber tow that is pliable. The pliable tackified tow can be used in braiding, weaving, or filament winding operations to produce dry fabric which contains a tackifier between the individual fibers such that preforms produced using the tackified tow can be readily shaped and hardened to retain that shape prior to molding.
