OS1517 カーボンナノチューブプリフォームを用いた高分子基複合材料の機械的特性(OS15-4 複合材料の変形と強度,OS-15 微視構造を有する材料の変形と破壊)

Abstract

Carbon nanotubes are nano-scale fibers that have high specific elastic modulus and tensile strength. The potential as reinforcement materials for polymers has, however, not been realized so far. In this study, two types of carbon nanotube preforms, unidirectional sheet and spun yarn, were used to achieve high efficiency of reinforcement. Composite specimens were fabricated using epoxy resin, and tensile tests were conducted for investigating tensile properties. The experimental results showed that using carbon nanotube preforms is effective for achieving high mechanical properties.
