A new model based on thermomechanics analysis is established to predict the coefficients of thermal expansion (CTEs) of 3D n-directional (n = 4, 5, full-5, 6, or 7)braided composites in this article. In this model, relationships between stresses and strains generated in fiber and polymer matrix are portrayed by a bridging matrix to obtain elastic constants of yarns. Based on equivalent fiber cross-sections and space projections of yarns, effective overall CTEs of 3D n-directional-braided composites are obtained. We introduce parameterization into the finite element modeling to complete our verification. The theoretical predictions are consistent with the finite element method and existing experiments. This article gives detailed insights into the effect of braiding parameters on CTEs to explore indication of addition yarns for thermal expansion performance. As an application of the proposed model, we utilize an improved genetic algorithm with objective weight mechanism and dynamic mutation to obtain the multi-objective optimization design for zero expansion 3D-braided composites.

An elastic‐plastic constitutive model to describe the nonlinear compressive stress‐strain behavior of fiber reinforced polymer composites was developed under the plane stress condition. Model predictions are based on the tensile properties and a tensile/compressive asymmetry coefficient. A variety of tensile and compressive tests were carried out on 0°, 15°, 45°, and 90° unidirectional and ±30° and ±45° angle‐ply thermosetting and thermoplastic polymer composite laminates to obtain the material parameters and validate the model, while the finite element implementation and applications to three‐point bending loading are discussed in the next investigation.

In this article, experiments and numerical simulation on the tensile loading properties of three‐dimensional five‐directional braided composites are studied. Herein, axial tensile loading tests were performed on braided composite and aluminum joints for propeller. A repeated unit cells model was established to analyze the micromechanical properties of the braided joint, a progressive damage model was established to evaluate the damage in the joint. In contrast to aluminum joint, which exhibited a tensile failure mode in only one direction, the braided joint exhibited both longitudinal and transverse damage failure modes, of which the transverse damage was the primary failure mode. The load‐displacement curves and damage morphology of the numerical simulation were in a good agreement with the experimental results.
