  • Composite structural components with reduced coefficient of thermal expansion
    Patent number: 10232559
    Abstract: A composite structural component includes a longitudinally extending elongated tubular duct of a first material having a first coefficient of thermal expansion, and a plurality of longitudinally extending elongated reinforcing members of a second material. Each of the reinforcing members is secured to the tubular duct along a length of the reinforcing member at spaced apart locations on the tubular duct, with the second material having a second coefficient of thermal expansion less than the first coefficient of thermal expansion, 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. Each of the plurality of reinforcing members is retained in a corresponding one of a plurality of longitudinally extending recesses formed in a peripheral wall of the tubular duct.
    Type: Grant

  • Thermoplastic components with reduced coefficient of thermal expansion
    Patent number: 9987794
    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.
