Fatigue resistant laminate which may be used at temperatures > 120.degree.C, andmore particularly in the construction of (air or space) vehicles. It comprises at least two metal plates interconnected by an intermediate layer of thermoplastic material reinforced by continuous filaments 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.degree.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.degree.C, such as poly-phenylene sulphides, polyetherketones or liquid crystal polymers. |
