Glass fiber strand mats, thermoplastic composites reinforced with the same and methods for making the same |
摘要 |
A needled mat adapted to reinforce a thermoplastic matrix material includes (a) a primary layer having a plurality of thermoplastic fibers in an amount greater than about 20 weight percent of the primary layer on a total solids basis, the primary layer being less than about 20 weight percent of the mat on a total solids basis; and (b) a secondary layer having a plurality of discontinuous glass fiber strands and having thereon a strand coating composition which is compatible with the thermoplastic matrix material, the secondary layer being essentially free of individual glass monofilaments.
