ABSTRACT:
Laminated reinforced thermoplastic sheets are made by preparing first and second porous sheets, each having 20% to 60% by weight of reinforcing fibers having a high modulus of elasticity and 40% to 80% by weight of a thermoplastic material differing from the thermoplastic material in the other sheet and applying heat and pressure to cause the sheets to consolidate and adhere together to form the laminate.
