摘要：
The static behaviour of two fibre reinforced composites was characterised after subjecting samples to natural exposure. The composites consisted of a thermoplastic matrix ( polyetherimide) reinforced with glass or carbon fabric. Natural aging involved exposing samples to the elements over a period of eight years. Subsequently, static ( tensile and interlaminar shear) tests were carried out with the aim of determining the mechanical properties of the materials after exposure. A substantial decrease in the value of these properties was verified and major damage to the surface of the materials was observed by micrographical analysis.
