Title:
MULTIAXIALLY REINFORCED LAMINATED MOLDINGS AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/020628
Kind Code:
A1
Abstract:
The invention provides a multiaxially reinforced laminated molding which has
high strength and little suffers from delamination and which brings about shortening
in the production time and reduction in the production cost; and a process for
the production of the same. The multiaxially reinforced laminated molding
(F) comprises fibrous reinforcement layers (SR1 to SR3) which contain reinforcing
fiber sheets and are laminated in such a way that the reinforcing fibers of the
reinforcing fiber sheets are arranged in three axial directions. Resin layers
(TP1 and TP2) are formed among the fibrous reinforcement layers. The resin layers
(TP1 and TP2) are each constituted of many granules of a thermoplastic resin material
which are distributed nearly uniformly and heat-fused with each other and which
also adhere to adjacent fibrous reinforcement layers through the heat fusion
of the material. The thermoplastic resin material contains many fine voids,
whereby the fibrous reinforcement layers and the resin layers are wholly uniformly
impregnated with a thermosetting resin material.
