Title:
FIBER-REINFORCED COMPOSITE MATERIAL AND SANDWICH STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/106649
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain a fiber-reinforced composite material which achieves a good balance between lightweightness and mechanical characteristics at high levels. The present invention is a fiber-reinforced composite material which contains (A) a resin and (B) reinforcement fibers, while having a porous structure part that has micropores having an average pore diameter of 500 μm or less as determined by a mercury intrusion method and a coarse cavity part that has a maximum length of more than 500 μm as a cross-sectional opening which is defined by the porous structure part.
