Influence of the structure of hybrid yarns on the mechanical properties ofthermoplastic composites

The fabrication process of thermoplastic composites using hybrid fabrics co mposed of yarns made from glass and PA6 fibres as prepregs is presented. Th e influence of the structure of hybrid yarns produced by employing commingl ed, texturing, twisting and friction-spinning technologies on the mechanica l properties of composites is discussed, The results of the investigation i ndicate that the best tensile and bending properties of composites were ach ieved while using fabrics made from textured yarns produced under optimal c onditions, which should ensure a minimum destruction of filaments during th e blending process.
