Mechanical properties of fibreglass and carbon-fibre reinforced polyetherimide after twenty years of outdoor environmental aging in the city of Gijón (Spain)

This paper reports the results obtained after carrying out tests on specimens of two types of composite materials. These materials have the same polyetherimide (PEI) thermoplastic matrix, but a different type of reinforcement. In both cases, the reinforcement is fabric, one being made of carbon fibre and the other, of fibreglass. The specimens were tested after various periods of exposure to an outdoor environmental aging up to a maximum period...
