Abstract: " Toray Cetex® TC915 is a newly developed unidirectional (UD) prepreg tape from Toray Advanced Composites (TAC) utilizing Polyamide+ (PA+) resin and standard modulus carbon fiber at 50% fiber volume content. The PA+ used in this product exhibits higher mechanical properties than standard PA6 with considerably lower moisture absorption (~50% less), which is one of the main concerns of using PA6. The PA+ thermoplastic resin has a ~25°C higher glass transition temperature (Tg) than PA6, making it a better choice for elevated use temperature applications. Composite structures produced with Cetex® PA+ TC915 UD tape are intended for applications across a range of industries such as sporting equipment, advanced mobility, and energy industries including oil/gas & hydrogen, where high performance is essential. In this work, physical characteristics and mechanical properties of the Cetex® TC915 product are evaluated and compared with Cetex® TC910, an established product form TAC, based on PA6 resin, with a wide range of applications across diverse industries. The microstructure of the composite structures was analyzed to understand formability, fiber distribution, and void content. Furthermore, we have tested composite tubular structures by 3-point bending to determine the performance of this material in complex composites structures. The bending tests revealed that TC915 composite tubes are stiffer and failed at ~18% higher load than TC910."
