Fabric‐reinforced shape memory polymer composites are lightweight, strong, formable, controllable, and suitable for various engineering and innovative applications. This study aims to fabricate and characterize electrothermal dual drive shape memory polymer composite fabrics (SMPCFs) of different densities with three‐dimensional (3D) angle‐interlock structures. The tensile properties, electrothermal properties, recovery forces (both tensile and bending), and shape recovery properties of SMPCFs were evaluated. The SMPCFs exhibited a tensile elongation of over 20% at the transition temperature. SMPCFs can reach transition temperatures when loaded with 2 V. The recovery forces are up to 225 N in tensile recovery force and 3.6 N in bending recovery force. In the shape recovery test, the recovery ratio exceeded 97%. Finally, the demonstration of recovery properties can stimulate the possibilities of SMPCFs in innovation and applications.Highlights Core‐shell structured composite filaments were prepared. 3D angle‐interlock composite fabrics: high strength, electrothermal drive. Tensile recovery force of composite fabrics can be up to 225 N. Elongation at transition temperatures was up to 20%.

“…The classical three-point and four-point loading methods are given in ASTM D790 and ASTM D6272, based on which, the temperature-dependent flexural properties have been investigated for various weave reinforced composites, including FR4 substrates, 15 multiply reinforced composites 16 and SpFPRC. 17 Still, thin specimens tend to flexure in a large configuration before failure, beyond the accommodation of these test configurations. These tests are only suitable for thin specimens' small deflection flexural moduli.…”

This study investigates the large deformation bending properties of a single-ply fabric reinforced polymer composite (SpFRPC) by the innovative counterweight balanced column bending test (CWB-CBT) and microscopic analysis.The influences of temperatures and asymmetric weave structure on SpFRPC's bending properties are emphasized. In glassy state at 15 C, SpFRPC failed in a brittle manner, with the ultimate moment and initial bending stiffness per width 19.16 Nmm and 448.61 Nmm 2 . The bending capacity decreased to negligible at 40 C in the rubbery state but vice versa for deformability, reaching the curvature of 0.135 mm À1 within maximum accommodation of this CWB-CBT fixture. The asymmetric weave structure enabled larger deformability when bent outward than inward, resulting in more significant stiffness and ultimate moment inward than outward. The transverse yarns' gaps were the weak locations of bending fracture, especially at weave intersection edges. In general, the present work provides an exploratory study for understanding the folding mechanical properties of the SpFRPC.

This study is based on the multi-scale finite element method and establishes RVE model of 2D woven fiber yarn and woven structure. The Stiffness matrix of plain, satin and twill 2D braided composites is calculated by applying Periodic boundary conditions and tensile shear loads in six directions. Write a UMAT subroutine to perform finite element simulation of the strength of woven RVE based on the three-dimensional Hashin failure criterion, and compare and verify it with existing experimental data. By comparing the load displacement curves of three types of braided composite materials under the same volume fraction, the stiffness and strength characteristics of the three types of braided composite materials, as well as the mechanical performance similarity issues caused by structural similarity, are studied.
