These laminated structures were tested under quasi-static perforation and low velocity impact loading to determine their structural responses and energy absorption characteristics. It has been shown that three-layer and five-layer laminates with lay-ups of GFRP-TPU-GFRP or TPU-GFRP-TPU and GFRP-TPU-GFRP-TPU-GFRP or TPU-GFRP-TPU-GFRP-TPU subjected to quasi-static perforation demonstrate an increased peak load and stiffness with the core thickness from 1 to 4 mm. Also, the TPU core laminates show a superior ductility in comparison to their GFRP core counterparts. The energy absorption values of the three-layer and five-layer TPU and GFRP based laminated structures under low velocity impact are higher than those under quasi-static loading due to strain-rate effect. However, the hybrid laminates with SBR and wire mesh as a core do not give much improvement on the impact perforation resistance of the laminates with the different size of wire mesh, as metal mesh plays a less important role in the laminated structures to resist perforation. In overall, TPU-GFRP-TPU-GFRP-TPU structure with 4mm thick GFRP core demonstrates the highest peak force, and the GFRP-TPU-GFRP-TPU-GFRP structure with 4mm thick TPU core offers the highest energy absorption.</p></div>","PeriodicalId":468,"journal":{"name":"Applied Composite Materials","volume":"31 6","pages":"2047 - 2069"},"PeriodicalIF":2.3,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142790378","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 means that design, manufacturing technologies and performance evaluation of composite honeycombs are important. In this review, grid, hexagonal, Kagome, corrugated and origami structure honeycombs and their associated manufacturing strategies have been summarised. In addition, more attention has been paid to textile structure composite honeycombs fabricated by weaving, braiding, or knitting techniques. Their mechanical performances have been extensively reviewed to clarify the relationship between structure and properties. Based on existing studies, the damage mechanisms of composite honeycomb structures are found to be insufficient; especially for the load-bearing mechanisms and predicting methods for honeycombs, which is a challenge for further development.

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. The results indicate that the SCL structure exhibits superior impact resistance, followed by SCCL, while the TO structure displays the lowest.

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.
