| Outline of Final Research Achievements |
The aim of this study is to fabricate the innovative polymer matrix composite (PMC) which is reinforced by carbon nanotubes (CNTs). As an introducing method of CNTs into PMC, synthesizing CNTs on the inorganic fibers such as glass fiber, tyranno fiber and PAN based carbon fiber was conducted. Then, uniform CNTs grafting process with high productivity was established by a combination of various catalysts and deposition conditions. Furthermore, the multi scale interfacial properties of PMC was improved by introducing CNTs, and it was found to be due to the anchor effects of CNTs. The CNTs grafted unidirectional composite was also fabricated and the tensile properties to 0, 10, 90 direction were studied. The anisotropy of CNTs composite and the mechanism of the stiffening effect were revealed.
