摘要：This extensive study investigated the influence of microstructure on the effective transver thermal conductivity of unidirectional glass fiber reinforced composites, in which the fibers are randomly disperd and the thermal conductivity of polyethylene matrix is a function of test temperature. The microstructure is characterized by parameters such as the number of fibers, fiber vol
ume fraction, fiber size, fiber arrangement and thermal property contrast. Firstly, a simple algorithm is developed to automatically generate clost-to-real random array of fibers in unit cell to reconstruct the composite microstructure. Then, the established two-dimensional random two-component composite unit cell is solved using finite element simulation and the obtained effective thermal conductivities are compared with the theoretical 社团活动记录
