Zusammenfassung:Today, the design of polymer parts by additive manufacturing subjected to large stress has undergone a clear advance with the new concept of continuous fiber-reinforced thermoplastic composites (CFRTPC). The optimization of fiber alignment is the main asset to improve strength and has been widely discussed by the research community. In this work, the effect of the intercalation of the polymeric matrix (ONYX) between layers of continuous fiberglass reinforcement has been analyzed in shear specimens. Onyx is nylon mixed with short carbon fibers. The results show how inserting polymeric layers among the continuous fiber ones improves the shear strength up to 25% and the stiffness modulus up to 18%.
