Influence of environmental conditioning on mechanical properties of carbon dry fibre preformed thermoplastic matrix composites manufactured via automated placement-resin infusion process

In the present work, dry fibre placement (DFP) of co-polyamide based carbon spreadtow bindered tape for fabrication thermoplastic acrylic resin composites was explored. The DFP followed by vacuum assisted liquid infusion (LRI) is expected to be an alternative process traditional preforming approaches. This research work looks at influence water immersion on performance studied. thermo-mechanical behaviour aged and unaged samples were carried out as a function temperature. flexural strength dropped 4 17% after one three months respectively. However, no significant changes observed in modulus compared unaged. interlaminar shear decreased 19% 35% month immersion. results complimented fractographic morphological studies.
