Experimental investigation of carbon long fiber reinforced polyamide 6 exposed to environmental conditions

To enhance the possibilities in lightweight constructions terms of processability and recyclability, fiber reinforced thermoplastics are a promising class materials. In this context, fiber-matrix interface has major influence on mechanical properties composite. With polyamide 6 (PA6) being hygroscopic thermoplastic, effects elevated humidity temperature behavior must be considered [1]. This study aims to characterize micro-mechanical material carbon long PA6 quasi-static tensile tests after exposure levels. Therefore, specimens conditioned different climates tested afterwards. order determine initiation propagation matrix cracks, failure, fracture, experiments conducted micro-scale with an average cross-section 0.03 mm2. The damage patterns captured using optical microscopy SEM images. conditioning at various levels discussed. main results qualitative description degradation due hydrothermal effects.
