Document Type and Number:
WIPO Patent Application WO/2021/106650
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain a fiber-reinforced composite material in which light-weight properties and mechanical properties are achieved at a high level. The present invention pertains to a fiber-reinforced composite material containing a resin (A) and a reinforcing fiber (B), and having a fiber-reinforced structure and cavities, wherein the fiber-reinforced structure has in-plane orientation portions in which the average fiber orientation angle of the reinforcing fiber (B) is 0-45°, and out-plane orientation portions in which the average fiber orientation angle of the reinforcing fiber (B) is greater than 45° and 90° or less, and the cavities are partitioned by the in-plane orientation portions and the out-plane orientation portions of the fiber-reinforced structure.
