On the Effects of Interacting Anisotropic Fibers on the Microbuckling in a Composite

An analysis of microbuckling in a composite with anisotropic fibers under compression is presented. The modelling accounts for the fiber interaction, the distinct difference in the properties of the fibers and the matrix, and also for the presence of the external boundary. Results are calculated for cases of perfect fiber-matrix bonding. It is demonstrated that the critical loading parameters can depend essentially both on the fiber anisotropy and the fiber interaction. These factors must be properly accounted for in order to get acceptable estimations of the critical loads.
