When composite materials occur crack, their fibrous locations willproduce bridging fibers. A symmetrical dynamic crack model of bridging fibers inunidirectional composite materials are not probed as deeply by virtue of the complexity,cockamamie and difficulty in mathematical operations. In the light of thetheory of complex variable functions, the problems discussed can be facilely translatedinto Remann-Hilbert problems. Analytical solutions of the displacements,stresses and stress intensity factors under the action of variable loads Pt6-x6, Px6-t5 are attained,respectively. After those analytical solutions were used by superpositiontheorem, the solutions of arbitrary complex problems were acquired.
