Abstract
A thermoplastic composite material may be formed by supplying the thermoplastic material to the opposite surfaces of the fabric material and by then passing the resultant material through the spaces between progressive pairs of rollers. The rollers in each progressive pair have a decreased spacing relative to the rollers in the previous pair so as to squeeze the thermoplastic material into the interstices between the fabric threads without compressing the fabric material. The resultant material may also be moved in a tortuous path, such as formed by a pair of rollers defining an S-configuration relative to the resultant material, to engage the opposite surfaces of the resultant material and squeeze air from the resultant material without compressing the fabric.
