Abstract
A method of adjusting a coefficient of thermal expansion of a member made of a fiber-reinforced resin, the method including: adjusting a coefficient of thermal expansion in a predetermined direction by increasing or decreasing a quantity of fiber having a grain direction in agreement with the predetermined direction. Also disclosed is a mold () for curing a cylindrical laminate () obtained by laminating prepreg. The mold includes a core die () and a surface die () outside the laminate including a plurality of partial surface dies (to). The partial surface dies are arranged to cover the entire circumferential surface of the laminate. Each of the partial surface dies is made of a fiber-reinforced resin in which a quantity of fiber having a grain direction in agreement with the circumferential direction differs from a quantity of fiber having a grain direction in agreement with an axial direction.
