Through tensile experiments combined with digital image correlation techniques, the spatiotemporal evolution of the full-field strain around the hole and the macroscopic progressive damage characteristics are systematically quantified. To address the challenges of damage recognition against complex backgrounds, an automated crack extraction algorithm combining the local standard deviation and the Hough circle transform is proposed. Precise tracking of the in-situ crack evolution using this algorithm confirms that the three-dimensional braided structure substantially delays the initiation of micro-cracks. Compared with the drilling process, the integrated braided structure significantly enhances the ultimate bearing strength, increasing the average value from 391.33 MPa to 535.61 MPa, with a single-specimen peak of 606.84 MPa indicating its upper-limit potential.

Conventional thickness-prediction methods typically ignore the effect of tangent-point number, which controls the crossover density and can therefore cause non-negligible underprediction for multi-tangent-point winding patterns. This work develops an interlacing-aware analytical thickness-prediction framework. First, a reduced local analytical model is introduced to quantify the additional thickness in representative circumferential and longitudinal interlacing/overlap regions. Second, the areal distribution of these regions is linked to the tangent-point number to construct a shell-scale thickness-correction coefficient, which is embedded into conventional cylindrical- and dome-thickness formulations to obtain an interlacing-corrected thickness distribution. The approach is validated against published measurements and our winding experiments for shells with different geometries and tangent-point numbers: the prediction error for local interlacing regions is below 6%, and the mean cylindrical-thickness error is below 2%. For dome sections, the proposed correction improves agreement with measurements compared with the conventional cubic-spline method, especially when the tangent-point number is large. The method provides a practical basis for geometric modeling and process-parameter design of filament-wound composite shells.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"33 4","pages":""},"PeriodicalIF":3.9,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613119","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 study presents a mesoscale finite element (FE) model of 3DWCs, incorporating the temperature-dependent progressive damage model for the constituent materials, to simulate the off-axis tensile behavior under various temperatures based on ABAQUS/Standard. The tensile responses and damage evolution processes are analyzed for four specific scenarios: axial tension at room temperature, off-axis tension at room temperature, axial tension at elevated temperature, and off-axis tension at elevated temperature. Key findings include: under 45° off-axis tensile loading, the multiaxial stress state reduces the material strength by approximately 90% compared with that under on-axis tension. At 200 °C under on-axis tension, thermal damage and matrix softening lead to strength reduction of approximately 40% relative to room-temperature on-axis tensile conditions. In contrast, under 45° off-axis tension at 200 °C, the thermal relaxation of yarns results in approximately 30% increase in strength compared with room-temperature 45° off-axis tension.

In this study, a series of sandwich-structured SMPCs were fabricated using a rib-knitted fabric core and plain-woven face sheets, specifically investigating the effects of layer count, loop orientation (0°/90°), and core configurations on their mechanical and shape memory behaviors. The results reveal that the mechanical properties are dominated by the knitted architecture, where the 90° orientation exhibits significantly higher flexural strength than the 0° orientation due to the interlocking mechanism of loop pillars. While the introduction of fabric reinforcement slightly constrains the shape recovery ratio (R<sub>r</sub>), it dramatically elevates the recovery force. Notably, the two-layers core SMPC in 90° direction achieves a peak recovery force of 15.6 N at 2% strain, representing a 6.0-fold increase over the neat shape memory epoxy polymer (SMEP). Furthermore, both shape recovery ratio and recovery force exhibited a non-monotonic parabolic trend with increasing bending strain, peaking at a critical threshold of 8%. This phenomenon is attributed to the energy-damage competition between increased elastic energy storage and irreversible structural degradation, such as loop over-stretching and interfacial debonding.
