EVALUATION METHOD OF CAVITY OF FIBER BUNDLE, AND EVALUATION METHOD OF RELATIONSHIP BETWEEN CAVITY OF FIBER BUNDLE AND IMPREGNATION OF LIQUID

摘要

PROBLEM TO BE SOLVED: To provide a method of clarifying the relationship between a cavity of a fiber bundle and resin impregnation by evaluating the cavity of the fiber bundle and then evaluating the impregnation of liquid in a place where the cavity is evaluated.;SOLUTION: An opening of a component (a) and an atmosphere side of an upper part of a suction filtration bottle are connected by a pipe equal to or larger than an inner diameter of the opening, a side part side of the suction filtration bottle and a vacuum pump are connected, a fiber bundle is mounted at a position of closing the opening of the component a, a component (b) is mounted at a position of matching the opening of the component (a) with an opening of the component (b), and the fiber bundle is fixed. The vacuum pump is operated, differential pressure generated before and after the fiber bundle is measured, and the differential pressure is an index of the cavity of the fiber bundle.;COPYRIGHT: (C)2014,JPO&INPIT
