One important reason for this is because they have interesting structural and mechanical properties compared to metallic materials. Their high strength-to-weight ratio makes them a preferred choice for high-stress applications. However, CFRPs are often subjected to various defects during their manufacturing that can significantly alter their structural integrity and durability. Amongst these defects, the occurrence of void formation (known as porosity) is the most common. Many methods have been developed for the characterisation of porosity including the ones based on the use of ultrasound data. The present work aims at providing a comprehensive review of the application of machine learning (ML) techniques to the mapping and characterisation of porosity across CFRP composites. The types of ML used, and their potentials for improving the accuracy of porosity detection are presented and discussed. It is particularly noted that ML techniques can extract unique features from CFRP complex ultrasound data with a relatively good level of accuracy. This result suggests that these techniques, particularly the convolutional neural network (CNN), would overcome the limitations of traditional signal processing techniques.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"32 4","pages":"1315 - 1339"},"PeriodicalIF":2.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10443-025-10342-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145168016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional ultrasonic testing techniques often fail to detect subtle material degradation, particularly when dealing with barely visible impact damage (BVID), which can go unnoticed but still significantly compromise structural integrity. In contrast, the proposed approach utilizes multi-directional ultrasonic Lamb wave analysis, a more advanced technique that offers greater sensitivity and precision in identifying damage at various stages of the composite’s lifespan. In this work, a damage indicator is defined based on the velocity profile of Lamb waves, which are sensitive to changes in material properties such as stiffness degradation. The Lamb wave-based methodology is rigorously validated through detailed comparisons with X-ray tomography. These comparisons reveal strong correlations between the two techniques, highlighting the effectiveness of the proposed ultrasonic approach in detecting BVID. Moreover, the study demonstrates that this methodology is not only highly sensitive but also scalable, making it suitable for industrial applications where automated inspection of composite components is essential.

Traditionally, polymer composites are made by incorporating rigid, high thermally conductive fillers within the polymer matrix. However, the filler loadings required to achieve significant thermal conductivity enhancement can impact the mechanical properties of the material system, often making them significantly more rigid or brittle than the base polymer. In this study, we developed a method to incorporate an ultra-high molecular weight polyethylene (UHMWPE) three-dimensional fiber mat and eutectic gallium indium alloy (EGaIn) liquid metal into an epoxy matrix. We integrated in-plane and cross-plane thermal conductivity measurements with flexural modulus assessments to understand the impact of the high thermal conductivity fillers on the thermal and mechanical response of the material. This approach enhances both the in-plane and cross-plane thermal conductivity of the composite, achieving thermal conductivities three times higher in the cross-plane direction and six times higher in the in-plane direction compared to the base polymer. Moreover, mechanical characterization reveals that the mechanical performance of the composite is comparable to that of a fiber-reinforced polymer composite, and the incorporation of liquid metal does not significantly impact stiffness, even at high filler loadings. This work demonstrates the potential of strategic composite design to achieve polymeric materials with optimized thermal-mechanical coupling. These new materials offer a solution to the challenges posed by higher power consumption in electronics, providing improved heat dissipation capabilities for more reliable devices.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"32 4","pages":"1399 - 1409"},"PeriodicalIF":2.9,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10443-025-10339-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed that the introduction of bonding surfaces noticeably reduced the generation of manufacturing defects within CFRP. Moreover, the bonding surface at 1/2 thickness as a neutral layer was conducive to the energy absorption of composite layers and the bonding surfaces at 1/4 and 3/4 thickness prevented the extension of shear cracks. As a result, compared to the specimen B0 without bonding surface internally, the specimen B1 with only one bonding surface at 1/2 thickness showed the best impact resistance in the drop hammer impact test. The peak force increased by 8.6% and the energy absorption before failure was increased by 30.6%. When three bonding surfaces were introduced and distributed at 1/4, 1/2 and 3/4 thickness, the best impact toughness was obtained in the pendulum impact test. The impact absorption work and impact toughness of the specimen B3 increased by 19.61% and 17.02%, respectively. However, the specimen B2 with two bonding surfaces distributed at 1/4 and 3/4 thickness showed poor impact bearing capacity.

The behaviour of these CFRP lugs was compared against conventional metallic aluminium lugs (L-Al) to evaluate their load-bearing performance under uniaxial tensile loading. Among the CFRP configurations, the L-C-QI lay-up exhibited the highest load-bearing capacity, even surpassing that of L-Al. In contrast, the L-C-H lay-up demonstrated the lowest strength within the CFRP group. L-C-S exhibited matrix cracking near the bore hole, facilitating stress relief similar to ductile metals. The L-Al lugs underwent significant plastic deformation and ligament necking, leading to 136% higher energy absorption compared to the best-performing CFRP lug (L-C-QI). Additionally, the study found that as the Hooke’s stiffness of the lugs decreases, the angle between the failure surface and the loading direction increases, indicating a transition in failure mode from shear tear-out to net section tension. Significant delamination was observed on the bearing side of the lug bore hole in CFRP lugs, while aluminium lugs exhibited plasticity on the bearing surface and ligament necking. These findings offer insights into the static tensile behaviour and failure mechanisms of composite and metallic lug structures.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"32 4","pages":"1755 - 1779"},"PeriodicalIF":2.9,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10443-025-10338-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moisture-exposed samples showed reductions of 55.54% in tensile strength, 55.58% in impact strength, and 41.46% in hardness, highlighting the detrimental effects of water absorption. Thermal cycling alone caused tensile strength reductions of 29.50% after 500 cycles due to thermal stresses and micro-crack formation.
