Abstract

In this work, end-of-life reuse of continuous fibre-reinforced thermoplastic composites from marine applications has been simulated by thermally reshaping (reprocessing) seawater-aged materials. Specifically, resin-infused, V-shaped glass/acrylic composites were seawater-aged (60°C; 170 hours) and reprocessed in a heated hydraulic press (120°C; 10 bar). Reprocessing promoted void collapse and increased short beam shear strengths. Unaged reprocessed materials retained 52% and 57% performance in flexural strength and modulus, (relative to virgin material), with corresponding retentions of 20% and 62% in the aged reprocessed materials, respectively. Ageing- and reprocessing-related flexural performance changes occurred due to mild matrix plasticisation and fibre misalignment, respectively.
