Layer-wise finite-element models can provide such prediction accuracy, but their computational cost becomes a major concern for large composite structures. To reduce this cost, a through-thickness partitioned homogenization strategy is proposed for composite forming simulation. In this strategy, the thickness of a carbon fiber-reinforced thermoplastic cross-ply laminate is divided into several partitions, and each partition is represented by a homogenized block with equivalent thermo-mechanical properties. Four categories of through-thickness partition configurations are first defined for an asymmetric hot-pressed laminate, and their prediction accuracy and total computational time are then evaluated against a layer-wise benchmark model. The results show that global through-thickness equivalence provides the lowest computational cost but cannot deliver reliable residual-deformation prediction. By contrast, retaining surface plies on both laminate surfaces is strongly associated with physically reasonable predictions, and retaining two surface plies on each side provides a practical balance between prediction accuracy and computational cost. After the bilateral surface arrangement has been fixed, relatively balanced and relatively symmetric thickness-wise layouts are preferred when further repartition is required. Based on these results, two representative implementation routes are selected for engineering demonstration on a variable-thickness composite wing-skin component. Compared with the layer-wise benchmark model, the two routes maintain low prediction deviations, with normalized root-mean-square deviation values of 3.7% and 2.4%, while reducing the total computational time by 87.4% and 75.8%.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"33 5","pages":""},"PeriodicalIF":3.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148628447","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}

Consequently, it remains a significant challenge to directly extrapolate the damage evolution laws established from laboratory-scale specimens to full-scale engineering structures. Accordingly, radial compression tests were carried out on CFRP tubes with various dimensions in this paper. Elastic wave signals during damage evolution were captured using acoustic emission (AE) technology. To address the issues that existing damage identification models are difficult to adapt to dimensional variations, a deep learning model incorporating a self-attention mechanism was constructed to realize the intelligent identification of damage modes for CFRP tubes with different dimensions. The results demonstrate a pronounced size effect in the mechanical performance of CFRP tubes: upon normalization, the peak load and displacement of the large-scale specimens decreased by 3.8% and 17.4%, respectively, compared to the small-scale specimens. Although fiber/matrix debonding remains the predominant damage mode for CFRP tubes of different sizes, its evolution characteristics differ significantly with varying dimensions. The proposed Tabular Attention ResNet model achieved a superior identification accuracy of 97.10% for damage modes across different CFRP tube dimensions.

To ensure assembly quality, the effects of line width and corner geometry on manufacturing accuracy were systematically investigated.

Accurate predictions of the cutting temperature and damage distribution with numerical simulation will help to suppress the damage efficiently. In previous studies, numerical models have been proposed to analyse the cutting temperature and damage during CFRP cutting. However, the effects of cutting conditions have not been systematically investigated, and the interaction mechanism between cutting temperature and damage remains limited. To address this issue, a numerical model with thermo-mechanical coupling was proposed to research the temperature distribution and subsurface damage. The heat generation and transfer mechanisms during the cutting were involved. The CFRP were treated as an equivalent homogeneous material, with the damage initiation criteria and damage evolution laws defined. The degradation equations of the mechanical properties with temperature variation were formulated during the material modelling. Based on this numerical model, the predicted material removal process, cutting force, and machining temperature showed good agreement with experimental results in a validated thermal range of 303–315 K. Then, the effects of the tool geometries and processing parameters on both the temperature distribution and subsurface damage depth were assessed. It was concluded that when the rake angle is positive, higher maximum temperature near the cutting edge (MT), smaller cutting forces and larger subsurface damage depths are produced under greater rake angles. The contact area and friction between the workpiece and the tool rake face are larger under greater cutting depth, resulting in an upward trend in workpiece temperature, and the cutting force and subsurface damage depth also increase with increasing depth of cut. At lower cutting speeds, smaller MTs and larger heat-affected zones are obtained, and the reduced cutting forces and subsurface damage depths are acquired under high cutting speeds.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"33 5","pages":""},"PeriodicalIF":3.9,"publicationDate":"2026-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615158","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 investigates the flexural performance and processing constraints of polymer composites reinforced with discarded jute coffee sacks and benchmarks them against primary flax fibre laminates and plywood reference materials. Com-posite specimens were manufactured by vacuum-assisted resin infusion using three polymer matrix systems: a petrochemical epoxy, a partially bio-based epoxy, and an infusable thermoplastic (Elium®). Flexural properties were characterised by four-point bending, and apparent fibre volume fractions were estimated to assess laminate consolidation quality. Composites reinforced with recycled jute coffee sacks achieved flexural moduli between 3.2 and 4.9 GPa and flexural strengths between 61 and 90 MPa, depending on the matrix system. In comparison, primary flax laminates exhibited significantly higher moduli (9.9–16.1 GPa) and strengths (153–234 MPa), while plywood reference materials showed comparable stiffness but a distinct failure mode dominated by tensile fracture of the bottom veneer and subsequent interlaminar crack propagation. The reduced performance of recycled jute composites is primarily attributed to processing-induced limitations, including heterogeneous textile architecture, local fibre misalignment, and porosity, which dominate the mechanical response. Differences between matrix systems were found to be secondary relative to the influence of reinforcement quality and impregnation effectiveness. Despite these constraints, the results demonstrate that post-consumer jute coffee sacks can be processed into resin-infused composites with reproducible, moderate flexural performance suitable for semi-structural applications with limited load requirements.
