The mechanical response and damage accumulation of carbon-fiber-reinforced composite laminates subjected to repeated low-velocity impacts were experimentally investigated. impact tests conducted on [902/-452/02/452]S quasi-isotropic [902/02]2S cross-ply under 16.8 J energy, respectively. For each impact, responses such as force-time, force-displacement energy-time curves recorded. trends peak force, maximum central displacement, energy absorption rate bending stiffness with the increasing...
In recent years, replacing steel bars with basalt fiber-reinforced polymer (BFRP) and ordinary concrete reactive powder (RPC) are considered effective solutions to the corrosion problem of in reinforced structures. order study bonding performance between BFRP RPC, a total 27 specimens were tested by pull-out test. The effects fiber volume content (0%, 1.5%, 2%), protective layer thickness (25 mm, 40 55 69 mm), bond anchorage length (3 d, 4 5 d; d is diameter bars) on studied. experimental...
Low-velocity impact (LVI) damage of 3D woven composites were experimentally and numerically investigated, considering different off-axis angles energies. The responses examined by LVI tests, the morphology inside was observed X-ray micro-computed tomography (μ-CT). Yarn-level evolution revealed developing a hybrid finite element analysis model. results show that has significant directionality determined weft/warp orientation composites. originates at bottom impacted area then expands...
The dynamic mechanical behaviors of the [Formula: see text] fiber-reinforced composite laminates subjected to double-position low-velocity impacts are investigated by finite element method. Two impact positions symmetrical about center impacted sequentially with three distances (10 mm, 20 and 40 mm) under energies (5 J, 10 J) study interference effect damage. For comparison, plastic damage model (PDM) elastic (EDM) established describe intra-laminar constitutive, respectively. Compared...
The low-velocity impact behavior of carbon-epoxy cross-ply composites was numerically investigated, examining the effect angle. A plastic continuum damage model, introducing cohesive interface to describe delamination damage, established and validated by available experimental data. Impact histories, progressive deformation, stress transfer, are respectively discussed. results show that an increase in angle intensifies action tangential force, gradually transfers energy absorption from...
Abstract The failure mechanism of 3D woven composites subjected to compression loading along principal/off-axis direction after low-velocity impact (LVI) was assessed by experimental and numerical methods. impacts under 26.8 J 80 energies were applied the specimens with off-axis angles 0° 45°. It can be observed that damages are direction-dependent, which is determined weft warp orientations. By performing compression-after-impact (CAI) tests, it found CAI strength principal more sensitive...
