| 内容記述 | This study clarified the compressive properties, fracture mode, and the factors which contribute to determining strength of carbon fiber reinforced plastics produced using spun yarn (spun yarn CFRP). The spun yarn CFRP was fabricated by impregnating the yarn with epoxy resin, and the test specimen was prepared by bonding acrylic blocks to both ends of the CFRP. The elastic modulus and compressive strength were obtained from compression tests, and the fracture strain was subsequently calculated based on these values. The compressive strength and modulus were inferior to those of CFRP reinforced with continuous carbon fibers, whereas the fracture strain was not necessarily lower. The fracture mode was characterized by kink band formation, similar to continuous fiber CFRP. The mechanism underlying strength was examined based on fracture strain. The comparison between experimentally obtained and theoretical fracture strains suggests that clusters of the fibers inclined at relatively large angle with respect to the yarn axis determine the compressive strength. X-ray computed tomography (CT) observation was then conducted to obtain the fiber angle distribution of spun yarn CFRP. As a result, clusters of fibers with such orientation angles were identified, supporting the validity of the suggested hypothesis. The insights gained from this study contribute to an understanding of the compressive performance and fracture mechanisms of spun yarn CFRP. | |||||||||||
