Document Type and Number:
WIPO Patent Application WO/2017/110532
Kind Code:
A1
Abstract:
The structure according to the invention is a structure comprising a resin, reinforcing fibers, and voids, wherein the volume content ratio of resin is within a range of from 2.5 vol% to 85 vol%, the volume content of reinforcing fibers is within a range of from 0.5 vol% to 55 vol%, voids are contained within the structure in a proportion within a range of from 10 vol% to 99 vol%, the thickness St of the structure satisfies the conditional expression: St ≥Lf2⋅(1-cos (θf)) when the length of the reinforcing fibers is taken to be Lf and the orientation angle of the reinforcing fibers in the cross-sectional direction of the structure is taken to be θf, and the compressive strength of the in-plane direction during 50% compression of the structure measured by JIS K7220 is 3 MPa or higher.
