A structural component is made by providing a main body and applying fibre material to the body so as to adjust the coefficient of thermal expansion and/or the modulus of elasticity of the main body. If the main body is made by molding, the fibre material may be embedded in the main body while the molding material is still soft. The fibre material may be loose long fibres adhesively secured to the main body. The fibre material may be a layer having a fibre orientation arranged in the direction in which stress is experienced by the structural component and/or the direction in which expansion of the structural component is to be resisted. Several layers of fibre material may be applied to the main body with the fibre orientation of different layers being in different directions.

A method of reducing stress on mechanical parts caused by differences in coefficients of thermal expansion between the parts and their structural support, comprising the steps of providing a structural support having at least two spaced apart support points at which mechanical parts are supported, the materials of the mechanical parts and the structural support having different coefficients of thermal expansion, adhering a plurality of superposed layers of fibre material to the surface of the portion of the structural support containing the support points, each layer having a direction of fibre orientation and the fibre orientation of different layers being in different directions, the number of layers and their direction of fibre orientation being selected to give said portion of the structural support a coefficient of thermal expansion so related to the coefficient of thermal expansion of the mechanical parts that the distance between said support points and the distance between said parts supported at the support points varies at substantially the same rate with temperature variations.
