Mechanical performance of aramid/glass fiber hybrid weft-knitting-reinforced composites under low-velocity impact

In response to the defects of easy delamination, poor impact resistance, and low toughness in laminates, intra-layer aramid/glass hybrid weft-knitted reinforced composites without lamination were designed prepared. This paper investigated tensile, bending, composites. Homogeneous with glass: aramid ratios 1:1, 2:1, 3:1, modes transverse hybrid, oblique vertical interlocking prepared by vacuum resin transfer molding (VARTM) technique. The tensile bending properties evaluated from stress, modulus, strain/deflection, a scanning electron microscope (SEM) was employed. analyzed peak force, maximum displacement, energy absorption. results confirm that interlacing brittle glass yarns exhibits positive effect. 50%, 33%, 25% fiber enhanced longitudinal strength 72.86%, 52.13%, 22.01%. mechanical are similar warp weft direction; contrast, other two methods demonstrate anisotropy. article implements preparation research non-laminated based on structures, which broadens design selection prefabricated components for
