The increase in nozzle diameter (from 0.4 mm to 1.0 mm) significantly enhanced the volumetric deposition rate, thereby reducing the time required to print each layer and shortening the overall manufacturing cycle. In addition, the larger nozzle diameter increased the width and height of each printed bead, which shortened the required path length per layer, further improving printing efficiency. Short-carbon-fiber filled polyamide 12 (PA12-CF) is used as the test material. The three-point bending test samples are prepared with the HFDM system, where the effects of extrusion width and layer height, as printing parameters, on the flexural properties are investigated. Furthermore, the fiber orientation within the deposited beads is measured using optical microscopy and imaging process software ImageJ. Experimental results indicate that with an increased layer height and extrusion width, PA12-CF samples exhibit improved mechanical properties, where the bending strength and stiffness can be increased up to ~ 20%, and ~ 30%, respectively. The fiber orientation angle measurements indicate that with smaller values of layer height and extrusion width, the fibers tend to align more parallel to the material extrusion direction. As these printing parameters increased, the fibers tend to align more diversely to the transverse directions, which ultimately benefits the increment of the flexural resistance of the entire samples. Additionally, isothermal annealing process improves the bending strength and bending modulus of the samples by approximately 12% and 13%, respectively.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"32 2","pages":"493 - 523"},"PeriodicalIF":2.3,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143778071","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}

Three types of 3DWTCs, namely shallow cross-linked (SCL), shallow-crossed curved joint (SCCL), and through orthogonal (TO), were fabricated using basalt fiber bundles and epoxy resin via the vacuum-assisted resin transfer molding (VARTM) process. Low-velocity impact tests were conducted at energy levels of 5, 10, and 20 J. To evaluate the damage characteristics of 3DWTCs, the observations were analyzed in terms of load-time curves, load-displacement curves, energy-time curves, and failure morphologies.

One important aspect here is the fiber orientation, being crucial for the thermo-mechanical properties of the part and being influenced by the uncertain material state and process conditions. Process simulations are an important tool for predicting the fiber orientation, but state-of-the-art simulations are normally deterministic and represent only one specific case. Performing enough deterministic simulations to model manufacturing uncertainties requires high numerical effort.

One of the most important failure modes of laminated composite materials is translaminar fracture under different loading conditions. In this research, the effect of temperature on the translaminar critical strain energy release rate (CSERR) of the composites reinforced with cotton fibers was investigated. The cotton/epoxy samples were placed at different temperature conditions of 30, 0, and -30 °C. The translaminar CSERR values of cotton/epoxy laminated composites were obtained under pure mode I, mixed mode I/II with two different loading angles, and pure mode II loading conditions. To calculate the translaminar CSERR based on experimental results, numerical modeling was also performed. Besides, a modified version of Mixed Mode Fracture Envelope criterion was proposed to predict the mixed mode I/II translaminar fracture behavior of the cotton/epoxy laminated composites at the mentioned temperatures. The results showed that lowering the temperature has a great impact on the translaminar CSERR. It was also concluded that the change in the temperature had the greatest effect on the value of the mode I translaminar CSERR.

The manufacturing through a hot-pressing process involves different (curing) stages and can reduce the spring-back with the proper combination of forming and curing. The cure-dependent spring-back is measured and analysed as a function of material constituents, fibre directions, laminate layups, and the process parameters including temperature, holding time and pressure. The results demonstrate that the spring-back ratio after full-cured process is relatively small and mainly depends on the mechanical properties of the metal sheet in laminates. However, temperature and time have a significant effect on the spring-back of partially-cured laminates and the same type of fibre prepreg combined with two different metal sheets have similar trends of spring-back reduction. Moreover, the study found that the hybrid laminates with aluminium sheet delaminate at low pressure after full-cured, while the delamination disappears as the pressure increases. The characterisation on cure-dependency of the spring-back contributes to a better understanding of the deformability of the metal-composite laminates during the hot-pressing process and offers an opportunity to tune the spring-back of these laminates.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"32 1","pages":"173 - 198"},"PeriodicalIF":2.3,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10443-024-10266-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142259649","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}
