Title:
COMPOSITE MATERIAL SUBSTRATE, PULTRUDED MATERIAL, METHOD FOR PRODUCING COMPOSITE MATERIAL SUBSTRATE, AND METHOD FOR PRODUCING PULTRUDED MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/008689
Kind Code:
A1
Abstract:
Provided are: a composite material substrate that makes it possible to adjust the performance of a composite material substrate molded by pultrusion in accordance with the performance required thereof; a pultruded material; a method for producing the composite material substrate; and a method for producing the pultruded material. The composite material substrate (60') comprises layers that extend in the lengthwise direction and that include reinforcing fibers (62f')-(68f') impregnated with a thermosetting resin, namely, a first layer (62') in which the fiber direction of the reinforcing fibers (62f') is oriented along the lengthwise direction and second layers (64')-(68') that are stacked on the first layer (62') and in which the fiber directions of the reinforcing fibers (64f')-(68f') are oriented in the direction of predetermined angles (64θ')-(68θ') with respect to the lengthwise direction and an in-plane direction of a facing surface facing the first layer (62'). The angles (64θ')-(68θ') in a pultruded material obtained by pultruding the composite material substrate (60') are equal to or larger than the angles (64θ)-(68θ) of the fiber directions of the reinforcing fibers with respect to the lengthwise direction.
