Abstract (en)
[origin: CA2465302A1] A fiber reinforced thermoplastic pipe member (54) is obtained by a novel continuous process in which the reinforcement fibers (22, 34, 44) are wrappe d about the outer pipe surface (14) in an unbonded condition while the pipe member (14) continuously moves in a linear direction and which is followed b y sufficient heating (50) of the moving fiber wrapped pipe member to cause thermal bonding between the applied fibers and the pipe member. Automated apparatus (10) for carrying out the continuous process is also disclosed.</S DOAB>
