Title:
FIBER REINFORCED THERMOPLASTIC RESIN STRUCTURE AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3453393
Kind Code:
B2
Abstract:
PURPOSE: To provide the efficient and economical manufacturing method of fiber reinforced thermoplastic resin structure, which is reinforced by long fiber so as to develop high mechanical strength and, at the same time, the dispersion properties and the like of reinforcing fibers in which are remarkably improved.
CONSTITUTION: In order to manufacture fiber reinforced thermoplastic resin structure containing 5-80wt.% of reinforcing fibers, which are removed in the form of continuous reinforcing fiber bundle from reinforcing fiber bundle aggregate, impregnated with molten thermoplastic resin under the condition being drawn and substantially arranged parallel to one another, the reinforcing fiber bundle, the scatter of the build-up of sizing agent in which is controlled to be lain within the domain ranging from -10% to +200% of its average build-up, is employed.
