Abstract: For the actual use of layer angle problems of the plain woven fabric laminated composite, a plain woven composite with 0º/45º/90º/-45º 4-layered laminates was prepared, and the dog-bone shaped specimen’s stretch under unidirectional tensile stress was investigated. During analysis, the specimen was perceived to be a macro-uniformed elastic material. Finite element model was established. The laminates were meshed by 8-node-solid elements. By step loading, the stress-strain relationship was obtained by numerical simulation, which is in good accordance with the test result. To predict the strength failure, the node reactions were selected as the boundary conditions of the cell sub-model. The results showed that the angle-layered laminates have less cracks and delimitations than the one-way layered. Moreover, under the same stress, the damaged resin elements are less, too. This will bring the angle-layered laminates with a higher strength.
