摘要

Fatigue resistant laminate which may be used at temperatures > 120 DEG C, and more particularly in the construction of (air or space) vehicles. It comprises at least two metal plates (2) interconnected by an intermediate layer (3) of thermoplastic material reinforced by continuous filaments (4) having a modulus of elasticity of at least 50 GPa, the laminate displaying, while externally unloaded, a compressive stress (of 0-200 MPa) in every metal plate and a tensile stress (of 0-500 MPa) in the continuous filaments. The filaments may consist of aramid, glass or carbon. The thermoplastic material may be an amorphous resin having a Tg > 140 DEG C such as, e.g., polyarylates, poly(ether)sulphones, polyetherimides, or poly-p-phenylene ethers, or a semi- or para-crystalline resin having a crystalline melting point > 170 DEG C, such as poly-phenylene sulphides, polyetherketones or liquid crystal polymers.
