Abstract
A composite structural component includes a longitudinally extending elongated base element and a plurality of longitudinally extending elongated reinforcing members each secured to the base element along a length of the reinforcing member at spaced apart locations on the base element. The base element is of a first material having a first coefficient of thermal expansion and a first modulus of elasticity. The plurality of longitudinally extending elongated reinforcing members are of a second material having a second coefficient of thermal expansion less than the first coefficient of thermal expansion, and a second modulus of elasticity greater than the first modulus of elasticity, such that the composite structural component has an effective coefficient of thermal expansion in the longitudinal direction that is less than 25% of the first coefficient of thermal expansion.
