ABSTRACT:
A fiber glass reinforced thermoplastic laminant of high flexural strength and a method of preparing the laminant is described in which special needling of the fiber glass mat used as the reinforcement is undertaken to minimize damage to the strands making up the mat during needling while insuring that the strands are moved during needling of the mat to provide strands in the mat that are transverse through the long axis of the mat after needling. The mat upon completion of the needling is then laminated with a thermoplastic resin to produce a sheet product having improved tensile characteristics.
