PARTIALLY IMPREGNATED TOW PREPREG AND APPARATUS FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a partially impregnated tow prepreg which surely secure a deairing pathway in forming, so that deairing is rapidly and easily achieved.;SOLUTION: The partially impregnated tow prepreg 1 has a configuration structure in which an impregnated part 4 impregnated with a matrix resin and an unimpregnated part 3 not impregnated with the matrix resin are aligned in the width direction of the tow 2. When a fabric 5 is formed using the partially impregnated tow prepreg 1 and a plurality of such fabrics 5 are laminated to form a laminate 6, the unimpregnated parts 3 overlap each other and air ways which communicate with each other in the laminating direction can be formed. Accordingly, a deairing pathway is surely secured in the laminating direction of the laminate 6 and deairing is rapidly and easily achieved.;COPYRIGHT: (C)2010,JPO&INPIT
