CBAM consolidates thermoplastic micro-powders precisely patterned on fiber laminates with an automated system, enabling effective matrix impregnation and higher fiber volume fractions. Micro-X-ray computed tomography revealed that CBAM composites contain smaller, more uniformly distributed micropores, whereas FDM parts exhibit inter-filament macro-voids. The distinct microstructures from both processes along with printing directions lead to different mechanical performance. In tension, CBAM composites achieved Young's modulus of 10.0–11.4 GPa and strength of 119.4–121.1 MPa, significantly higher than FDM (4.2–8.1 GPa, 54.7–81.5 MPa), with reduced sensitivity to print orientation due to improved interlayer bonding. Flexural tests showed CBAM's modulus (8.1 GPa) and strength (103–106 MPa) remained consistent across orientations, again surpassing FDM, particularly for 45° flat specimens. In compression, CBAM exhibited lower strength (63.3 MPa at 0°, 54.4 MPa at 90°) than FDM (85.4–91.7 MPa), attributed to matrix-dominant properties. These results demonstrate that CBAM's improved tensile and flexural performance arises from the coupled effects of fiber orientation, volume fraction, and void morphology. To demonstrate application potential, a two-blade propeller was fabricated using CBAM with non-woven glass fiber and PA-12. Ten blades were produced within 3 h, meeting dimensional tolerances &lt;1 mm—substantially faster than the 35–50 h typical of FDM. These establish CBAM as a rapid, precise, and structurally advantageous composite manufacturing technology for aerospace and advanced mobility applications.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"309 ","pages":"Article 113035"},"PeriodicalIF":14.2,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145098218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multi-physics material models of IM8 HiMax® and 1078-1 resin are used to simulate and predict the optimal cure cycles. Critical mechanical testing compares the outcomes from different cure cycles, including a baseline process nominally followed by the industry. Results show that the accelerated-cure panels (50 % cycle time compared with the baseline) are of good quality and perform just as well regarding the mechanical properties.

Specifically, delamination initiation serves as a precursor to structural failure, which is often difficult to detect during damage inspection. Identifying and sorting delamination initiation in samples not only increases operational safety while providing critical information for end-of-life decisions, which influences both the service life extension value and the efficiency of fiber extraction during recycling. This research addresses two challenges: (1) developing a nondestructive, ex-situ framework to sort composite materials based on damage severity, particularly delamination, and (2) understanding how damage in composites influences resin removal during pyrolysis. Both experimental work and finite element analysis were performed to predict critical stress levels that are associated with delamination onset. Based on these results, three loading levels 50 %, 75 %, and 90 % of maximum stress, were selected for controlled experiments, generating composite samples with varying extents of damage for machine learning model training. Microscopic imaging of these samples confirmed the damage progression from matrix cracking to delamination, validating the computational predictions. We explored supervised machine learning using dielectric measurements to classify damage states. Preliminary results show an artificial neural network can identify early delamination which is a potential precursor to failure, with 94.44 % accuracy on our dataset.

Herein, a functionalized ink composed of MV0.3/AC/PVDF for both bulk and direct ink writing (DIW) printing, enabling the construction of both electrodes with customized structure in 1-layer and 2-layer configuration. In the AASC testing, the 2-layer printed AASC(3DP-2LMV0.3) revealed a significantly high areal capacity up to 1.54 C cm<sup>−2</sup> at 6.2 mg cm<sup>−2</sup> mass loading. Furthermore, the 3DP-2LMV0.3 delivered a high areal energy density 333.4 μW h cm<sup>−2</sup> compare to 3DP-1LMV0.3 and BMV0.3, without compromising areal power density (2.1 mW cm<sup>−2</sup>) at current density (1.24 mA cm<sup>−2</sup>), with the excellent retention of 94.8 % after 5 k charging/discharging cycles. This work highlights the potential of DIW-3D printing as a scalable approach to construct vertically aligned porous structure with thick electrode scaffolds. It offers a promising platform for advanced energy storage applications with reduced solution resistance for ion/electron transport compared to bulk electrode structures.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"308 ","pages":"Article 113022"},"PeriodicalIF":14.2,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145045893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
