“…This demonstrates a decrease in the stiffness of the composite by approximately 43% due to increased agglomeration within the composite matrix 60 . During the contact of the impactor with the surface of the specimen, three states may occur 61 . In the first state, the energy of the impactor ( E max ) is lower than the penetration threshold of the composite material.…”

In this study, the impact of incorporating graphene oxide (GO) nanoparticles into the matrix of aramid fiber reinforced polymer (AFRP) composites was investigated. The GO nanoparticles were dispersed in the AFRP matrix at three different weight percentages: 0.1%, 0.3%, and 0.5%. The fabrication of the GO dispersed AFRP nanocomposites was achieved using the vacuum assisted resin infusion molding (VARIM) method, and the AFRP plates were cut using a water jet. The sectioned specimens of the fabricated nanocomposites were subjected to low velocity impact tests. The effects of introducing GO nanoparticles at different percentages were evaluated by analyzing the contact force, deflection, maximum absorbed energy versus time and contact force versus deflection curves. Finally, the key parameters of low velocity impact, including contact force, deflection, and maximum absorbed energy, were compared for the different fabricated AFRP nanocomposites. Based on the results, the AFRP composite with 0.3 wt.% of GO nanoparticles exhibited the best performance under low velocity impact loading conditions. However, the agglomeration of nanoparticles became a significant challenge when higher percentages of GO nanoparticles were added to the composite structure. The findings highlight the importance of determining the optimal percentage of nano materials for incorporation into composite structures.

“…Thus a multiscale FE model consisting of a mesoscopic deformed part and a macroscopic homogeneous part was considered. Referring to our previous work and considering the geometrical symmetry of the specimen, 35,36 a quarter macro-meso hybrid model is proposed to effectively balance the calculation accuracy and calculation efficiency. 37,38 In this paper, the highly adaptable second-order tetrahedral cell (C3D10) was used to mesh the unit-cell model.…”

Abstract2.5D woven structures are of interest in new thermal protection systems for their excellent interlayer properties and structural stability. In this paper, dense (CDP) and lightweight (CLP) carbon/phenolic 2.5D woven composites were prepared. Quasi‐static tensile experiments were performed on the specimens before ablation (TCDP‐0, TCLP‐0) and after ablation for 30 s (TCDP‐30, TCLP‐30). A quarter macro–meso hybrid model that takes into account the degradation of material properties after ablation and ablative crack pores was innovatively proposed. The predicted tensile elastic modulus is within 9% error from the experimental results. The results show that TCDP‐30 and TCLP‐30 have rapid damage expansion and lethal injury at smaller displacements than the pre‐ablation specimens. The displacement of the maximum load point of TCDP‐30 is 38.7% lower than that of TCLP‐30. The forms of damage in TCDP‐30 are dominated by matrix fragmentation and matrix cracks. The damage forms of TCLP‐30 are dominated by debonding and delamination.Highlights Micro‐CT was used to collect matrix fabrication defects and ablative crack pores defect. A quarter macro–meso hybrid model that takes into account the degradation of material properties after ablation and ablative crack pore was innovatively proposed. The tensile failure mechanism of the material after ablation was revealed by the combination of experiment and numerical method.
