Abstract To investigate the mechanical response and failure mechanism of short carbon fiber reinforced polyether‐ether‐ketone (SCFR‐PEEK) composite under high‐velocity impact foreign bodies different shapes, experiments numerical simulations SCFR‐PEEK were carried out with blunt projectile, hemispherical ovoid projectile in velocity range 33.6 ~ 163.8 m/s. The results show that ballistic limit is highest lowest velocities studied. resistance better than projectile. has weakest at lower...
The M-type GFRP foldcore was prepared by thermal pressing method, and bonded with the panel to obtain complete sandwich structure filled core foaming silica gel. influence of filling foam, impact energy position on damage mode dynamic response under low-velocity is studied through experiment. results show that resistance Node-impact better than Base-impact low impact, while worse high impact. Filling foam could effectively improve properties plate decrease degree plate. In addition, absorb...
Abstract In this work, the failure mode and ballistic protection capability of carbon fiber aluminum alloy laminated target plate under impact high‐speed projectile body were studied by test. The effects lamination sequence warhead shape difference on resistance laminates analyzed. Two kinds bodies, flat oval head, used to carry out multiple experiments four groups targets with different stacking sequences. By analyzing result, it is found that has a significant effect anti‐impact...
Abstract Fiber‐metal laminates (FMLs) are attracting much attention from researchers as emerging aerospace materials. In this paper, 1060‐H112 aluminum alloy‐carbon/glass fiber were prepared by vacuum bagging method. Subsequently, based on tensile, three‐point bending and low‐velocity impact experiments, the quasi‐static mechanical properties well dynamic response to of two investigated. The results show that carbon metal laminate (CARALL) has stronger tensile strength inter‐ply consistency,...
The perfluorosulfonic acid (PFSA) ionomers are key materials for proton exchange membranes (PEMs) and catalyst layers (CLs). Their morphology is profoundly influenced by the chain assembly behavior of PFSA in dispersions. Hence, we combine characterization techniques dynamic light scattering (DLS), small-angle X-ray (SAXS), cryo-transmission electron microscopy (Cryo-TEM) to study nanostructures dispersions, provide a structure model diverse water/ethanol solvent. It seen that self-assembly...
The M-type GFRP (Glass Fiber Reinforced Polymer) foldcore was prepared by thermal pressing method, and bonded with the panel to obtain complete sandwich structure filled core polyurethane foam. influence of foam filling, impact energy position on damage mode dynamic response under low-velocity is studied through experiment. results show that resistance N-side better than B-side impact. Foam filling could effectively closing gap between In addition, absorb about 15%-25% more empty plate.
Abstract In order to investigate the effect of graphene oxide (GO)/multi wall carbon nanotubes (WMCNTs) on mechanical properties and low‐velocity impact response magnesium‐based fiber metal laminates (FMLs), FMLs specimens reinforced with GO, WMCNTs or their mixture were prepared, quasi‐static tensile drop hammer tests performed. The test results showed that performance could be improved by adding a certain concentration nanoparticles. strength increased 14.9% 26.6% when GO is 0.6 wt%,...
Abstract To investigate the influence thickness has on impact resistance of glass fiber woven composite laminates, a series tests 1–5 mm‐thick laminates impacted by hemispherical‐nosed projectile one‐stage gas gun are conducted. The ballistic limit, energy absorption, failure mode, and damage mechanism is analyzed. results show limit velocity mm to increase in linear manner. It found that laminate 5 2.8 times greater than 1 thickness. As increases, absorption laminated plate decreases...
Abstract The aim of this paper is to explore the effect polyurethane foam filler on out‐of‐plane compressive property and low‐velocity impact resistance orthogonal corrugated sandwich panel by experimental method. results show that filling increases energy absorption specific 64.75% 38.22% under load, respectively. Furthermore, during compression, filled causes core strut undergo pure buckling failure gradually folds rather than brittle fracture. Under impact, strengthening first peak load...
Abstract To obtain the mass distribution law of behind-armor debris(BAD) produced by EFP vertically penetrating armored steel, numerical simulation calculation targets with different thicknesses (30mm ∼ 70mm) at impact velocities (1600m/s 2000m/s) was carried out using method verified experiments. Several classical natural fragment models are used to study BAD generated and target plate. The results show that Mott formula is not suitable for describing mass-quantity warhead penetration,...
