To address this limitation, this study develops a comprehensive multiphysics simulation framework that captures the consolidation-driven evolution of V<sub>f</sub>, resin pressure, temperature, and degree of cure (DoC) in filament-wound composites. The framework integrates thermochemical, resin-flow, and mechanical fields via finite element subroutines. The effects of consolidation-driven V<sub>f</sub> evolution on residual stress development are investigated. Results indicate that processing conditions significantly influence V<sub>f</sub>, which affects the thermochemical response and, consequently, the resulting mechanical performance by reducing internal exothermic heat generation and peak curing temperatures. These reductions suppress the thermal and chemical shrinkage strains responsible for residual stress buildup. Consequently, the framework predicts significantly lower residual stresses than those obtained using static-V<sub>f</sub> approximations.

Unfortunately, a comprehensive understanding of the formation mechanisms of micro-voids during polymer processing is currently lacking. The present study considers micro-void formation at fiber interfaces, particularly those occurring at the end of suspended fibers. Micro-computed tomography (µCT) image acquisition techniques are used to characterize microstructural features of a 13wt% carbon fiber reinforced acrylonitrile-butadiene-styrene (CF/ABS) composite bead manufactured via Large Area Additive Manufacturing (LAAM). The results reveal a significant collection of micro-voids at the tips of fibers approaching 80% of the total micro-void volume fraction. In addition, fiber tip micro-voids are relatively larger and less spherical than micro-voids isolated within the ABS matrix. Theoretical formulations of several known mechanisms for micro-void formation during LAAM material processing indicate that localized fluid pressure likely plays a pivotal role in micro-void formation. To better expose this mechanism, we simulate the hydrostatic flow-field pressure distribution surrounding a single rigid fiber suspended in simple shear flow using finite element analysis (FEA). Computed results demonstrate that the polymer matrix pressure decreases significantly at the fiber ends where significant micro-void formation is experimentally observed to occur. Our approach provides the fiber surface pressure distribution in simple shear flow that typifies nozzle regions with extreme flow conditions, enhancing our understanding of micro-void development mechanisms as the polymer melt flows through the nozzle.</p>\u0000 </div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"33 2","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146027326","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}

This paper systematically investigates the effect of the fiber bundle aspect ratio, as a key mesostructural design parameter, on the impact performance of braided composites. In this study, three types of laminates with different aspect ratios were fabricated by varying the braiding mandrel radius and were tested under impact energies of 20 J, 30 J, and an energy level adjusted to eliminate the effect of thickness. The results show that the high-aspect-ratio specimen exhibited a higher peak load and was not perforated, whereas the low-aspect-ratio specimen underwent perforation failure, indicating a significant enhancement in its impact resistance. Damage mechanism analysis reveals that the fiber bundle aspect ratio directly determines the single-ply thickness and crimp angle of the yarns: the large crimp angle caused by a low aspect ratio induced severe interlaminar shear stress under impact, promoting early and extensive delamination as the dominant failure mode. Conversely, the lower crimp angle in the high-aspect-ratio specimen effectively suppressed delamination, compelling the system to dissipate energy through the higher energy-threshold mechanism of bottom-ply tensile fiber fracture. This fundamental shift in the damage mode, from delamination-dominated to fiber-fracture-dominated, was corroborated at both macro- and meso-scales using quasi-static indentation (QSI) tests and X-ray micro-computed tomography (µ-CT).
