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}

The model is validated by comparing the data of composite laminates affected by fire in literature. Then, the model is used to analyze the temperature and decomposition degree of the winding layer of the gas cylinder under different heat flows. Results reveal that the higher the heating heat flux received by the gas cylinder, the higher the temperature and degree of decomposition of the winding layer after heating is completed. Under a heat flow of 80 kW/m<sup>2</sup>, as the heating time prolongs, the surface temperature of the gas cylinder continues to rise. In addition, the relationship between the temperature and degree of decomposition of the gas cylinder winding layer is related to the depth, peak decomposition rate, and time to reach the peak.

A drop hammer impact experiment was conducted on specimens with varying upper and lower panels thicknesses, utilizing Digital Image Correlation (DIC) technology to monitor the deformation and strain of the impacted panels. The study identified the upper panel as the initial failure point, characterized by matrix cracking, fiber fracture, and interlayer delamination, with the honeycomb core primarily experiencing crushing damage. A critical impact energy threshold of 40 J was established for upper panel penetration, with lower panel damage becoming evident at energies exceeding 80 J.

This work aims to clarify contradictory results of the effect of GO on the mechanical properties of bio-based polymers by synthesizing high-quality and low-cost GO. To this end, we investigated the effect of adding solvents (acetone, THF) on the mechanical behavior of polymers subjected to several types of static loading. Five different types of materials were examined: neat epoxy (reference material), enhanced epoxy without solvent, enhanced epoxy with acetone solvent, enhanced epoxy with THF solvent, and epoxy enhanced with pure graphite powder. The concentration of GO or graphite was 0.5 wt%. The findings were analyzed using Scanning Electron Microscope (SEM), Thermogravimetric Analysis (TGA), and Raman Spectroscopy. A significant increase in the tensile strength and fracture toughness of polymers filled with GO without solvent was observed compared to the enhanced materials with solvents. SEM analysis of the fracture surfaces revealed resin penetration into the graphene sheets, indicating strong bonding between amino groups and graphene oxide in the case of the enhanced epoxy without solvent. In contrast, in the enhanced epoxies with solvents, the GO-epoxy bonding appeared to be either deteriorated or destroyed. TGA analysis revealed that both neat and GO-reinforced resins without solvent were thermally stable up to 360 °C.

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.
