An integrally formed article of thermoplastic composite members having a first member which is a preformed laminate of a plurality of thermoplastic composite fabrics comprising reinforcing fibers and a thermoplastic resin, and a second member which is a partially bonded laminate of a plurality of thermoplastic composite fabrics comprising reinforcing fibers and a thermoplastic resin, a not-bonded portion of the second member being bent, brought into contact with the first member, and heated at a temperature equal to or higher than a melting point of the thermoplastic resin under pressure so that the not-bonded portion of the second member is integrally bonded to the first member.

Thermoplastic composite fabrics and formed article produced therefrom

The composite material having improved toughness is produced by preparing a laminate from reinforcing fibers and a thermoplastic resin; heating the laminate at a temperature higher than a melting point of the thermoplastic resin under pressure; quenching the composite material at an initial cooling rate of 100.degree. C./min or more, thereby providing the PEEK in the resulting composite material with a degree of crystallization equal to or lower than 75% of the maximum degree of crystallization of the thermoplastic resin.
