The interest and demand towards the use of thermoplastic composites have been gradually increasing due to their high damage tolerance, recycling, and energy absorption capability compared to thermoset composites. Despite such positive properties, thermoplastic materials have a negative side, which is their high melt viscosity. The solution to this problem can be achieved by using hybrid yarns in which reinforcement and matrix fibers are homogeneously mixed together. In this work, the aim was to investigate the mechanical properties of thermoplastic composites to be prepared using continuous glass fiber/polyethylene terephthalate (CGF/PET) hybrid yarns in different proportions by volume. CGF/PET hybrid yarns containing glass fiber in different volumes (45 and 55) were produced, woven and then transformed into thermoplastic composite test plates using hot press. Tensile, 3 point bending and impact tests were used to investigate the mechanical properties.
