    摘要: A composite laminate designing method includes: deriving, on a basis of allowable strains corresponding to fiber orientation angles in a composite laminate having the fiber orientation angles, an allowable load region that represents in three dimensions a combination of an allowable X-direction load in a predetermined x direction in a plane orthogonal to a lamination direction in which layers of the composite laminate are laminated, an allowable Y-direction load in a y direction orthogonal to the x direction in the plane orthogonal to the lamination direction, and an allowable shearing load in a shearing direction in the plane orthogonal to the lamination direction; and determining whether a working load acting on the composite laminate is included within the allowable load region.
