Low velocity impact tests were conducted using a drop weight tester at various velocities. Load-displacement curves and energy absorption results, combined with damage morphology analysis, were used to identify different damage modes and the critical energy for complete penetration. High-speed imaging combined with digital image correlation (DIC) technique was employed to examine the full-field strain distribution and damage evolution during the impact process. An enhanced damage-tracking algorithm was implemented, specifically designed for large out-of-plane deformations and discontinuities and could be broadly applicable to other material systems that undergo large out-of-plane deformations. Results showed that maximum load increased with impact velocity, while bending stiffness remained constant. At lower velocities (1 m/s), elastic behavior with significant rebound was observed, with no delamination or penetration. At 2 m/s, the penetration energy threshold was determined to be 44.3 J, while at 3 m/s, the composite was fully penetrated, showing increased maximum load, displacement, and plastic energy absorption. Higher impact velocities led to longer cracks, with weft cracks consistently exceeding warp cracks in length due to the straight arrangement of weft yarns, which facilitates damage propagation. Microstructural analysis identified fiber fracture, interfacial debonding, and matrix cracking as the main failure modes of the 3D woven Kevlar/epoxy composite. These findings provide valuable insights into the damage mechanisms, strain evolution, and mechanical behavior of 3D woven composites.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"32 4","pages":"1579 - 1595"},"PeriodicalIF":2.9,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, compression moulding process simulations were performed to predict fibre orientation using Autodesk Moldflow. Model parameters for process simulation were calibrated until the predicted fibre orientation matched the orientations obtained using micro X ray-Computer Tomography on PA6-LFT40 plates. The calibrated fibre orientations were then mapped to a finite element method (FEM) solver mesh to perform standard static three point bending test. Tensile tests served as the corresponding material model inputs for the simulations. Using mapped FEM simulation, the deviation between simulation and tests were less than 10% that is much better than without mapping. Finally, using the experimentally determined Haigh diagram, three point bending fatigue testing of PA6-LFT40 at different load levels at a stress ratio of R = -1 were performed and evaluated by using FEMFAT.

Laminates were produced using a hand lay-up technique with six layers of bidirectionally woven basalt fibers and polyester resin. Thermal analyses (DSC and TGA) established that 500 °C is the optimal temperature for complete combustion of the polyester matrix, which is fully removed with minimal impact on the fiber surface. The energy released during resin combustion, measured using the Mahler-bomb method, was evaluated for potential reuse to improve energy efficiency in the recycling process. The basalt fibers exhibited exceptional thermal stability, showing only a 1.75% mass loss during the process. Recovered fibers retained their original continuous woven structure, enabling the fabrication of new laminates. Chemical and morphological assessments of the recycled basalt fibers via Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) confirmed minimal alterations in fiber properties. Mechanical testing using three-point bending revealed that the recycled laminates experienced a decrease in flexural strength and flexural modulus of approximately 10.39% and 4.51%, respectively, compared to virgin laminates. Furthermore, the failure mechanisms differed between the two systems: while virgin laminates failed through a combination of fiber breakage, matrix cracking, and interlayer delamination, the recycled laminates predominantly exhibited interfacial failure. As a result, these findings support the feasibility of recycling basalt fibers with minimal impact on mechanical performance, presenting a sustainable approach for composite material reuse.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"32 4","pages":"1617 - 1638"},"PeriodicalIF":2.9,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing micromechanical models often oversimplify particle geometry, neglecting nonconvex shapes, and fail to comprehensively capture the interplay between particle aspect ratio, particle volume fraction, stress distribution, and damage mechanisms. In this study, a novel microstructure-based micromechanical finite element modeling method that incorporates nonconvex particle shapes is proposed to accurately represents the realistic geometry of SiC particles. This approach enables the analysis of how particle characteristics, such as aspect ratio and volume fraction, influence the stress distribution, damage initiation, and fracture propagation in A359/SiC composites. The model accounts for all potential fracture modes, including brittle cracking of SiC particles, ductile damage of the aluminum matrix, and particle–matrix interface debonding. Results demonstrate that the tensile strength and elongation both increase as the particle aspect ratio rises. Needle-shaped particles exhibit superior load bearing capacity and serve as more effective reinforcements compared to stubby-shaped particles. Although increasing the particle volume fraction enhances the fracture strength of the composite, the elongation is reduced concurrently due to the brittleness of the particles and the intensified stress concentration. This study provides a significant advancement over previous models by incorporating realistic particle geometries and offering new insights into the role of microstructure in governing the mechanical and fracture behaviors of A359/SiC composites.
