面内配向を有する強化基材を含む複合材料の熱・電磁気特性のマイクロメカニックス解析

Modified equivalent inclusion method is applied to a composite material containing various misoriented reinforcements. The interaction stresses induced in the composite and the total strain of the composite can be expressed as a function of orientation angle of reinforcements. The distribution function is devised to be continuous change from two-dimensional distribution to unidirectional one of reinforcements. By using the distribution function, macroscopic linear coefficients of thermal expansion α are obtained in addition to the macroscopic elastic modulus. α22 out of plane lies in reinforcements is affected by the in-plane distribution of reinforcements.
