Outline of Final Research Achievements |
In this study, a new method to measure three dimensional thermal diffusivity for carbon fiber reinforced plastics in both micro-schale and macro-schare with high accuracy has been developed. This method has been applied to fiver orientation detection method for carbon fiber reinforced thermoplastic, and measurement technique and theory to obtain both thermal conductivity distribution and fiber orientation distribution have been developed.

Academic Significance and Societal Importance of the Research Achievements |
近年自動車などに応用が期待される熱硬化性炭素系複合材料は繊維の分散に偏りが生じうるため,その分布を非破壊で迅速に検知できる手法が求められている。本研究では独自の熱拡散率分布測定手法を確立し,本手法を複合材料の配向同定法に応用することで,従来の技術にはない非接触式配向同定法の創出に貢献した。
