COMPOSITE MATERIAL REINFORCEMENT SUBSTRATE, COMPOSITE MATERIAL, AND PRODUCTION METHOD FOR COMPOSITE MATERIAL REINFORCEMENT SUBSTRATE

摘要

[Problem] To provide a reinforced substrate for a composite material, a composite material, and a method for manufacturing a reinforced substrate for a composite material in which warping of the composite material caused by shrinkage of resin can be minimized.[Solution] A reinforced substrate 100 for a composite material has a first region 111 that includes reinforcing fibers 110 in which a fiber direction is aligned in a single direction, and a second region 112 that includes the reinforcing fibers aligned in the same direction as the fiber direction and that is fashioned to a thickness H, which is less than a thickness Hof the first region. The first region and the second region are lined up in alternating fashion in a plane along a direction intersecting the fiber direction.
