Abstract:
The present invention relates to a thermoplastic prepreg production method which is developed in order to be used as structural and visual material in all industrial fields, mainly aviation, defense industry, medical, marine and automotive, and which enables thermoplastic resin to be impregnated into non-crimp dry fabric formed by weaving yarn (A) layer (matrix) manufactured from at least unidirectional reinforcing fiber with yarn (B) layer manufactured from at least unidirectional polymeric fiber. The layers forming the non-crimp fabric are formed by including the meltable thermoplastic yarn (C) in weft and warp direction into the system. The objective of the present invention is to enable the resin used in prepreg application to impregnate more into the non-crimp dry fabric manufactured by weaving method compared to the conventional applications. In other words, the objective of the present invention is to provide a thermoplastic prepreg method which provides the wettability of the fabric produced with a yam (A) manufactured from reinforcing fibers.
