Effect of nanoclay on ballistic behavior of woven fabric composites: Experimental investigation

Abstract

In this article, the influence of nanoclay Closite 30B on E-glass/epoxy laminated composites behavior has been investigated by ballistic impact, X-ray diffraction and tensile tests. The fiber glass used is a plain weave of 200 g/m2, whereas nanoclay is an organically modified montmorillonite nanoclay (Closite 30B). The epoxy resin system is made up of epon 828 as the epoxy prepolymer and Jeffamine D-400 as the curing agent. The nanoclay particles are dispersed into the epoxy system in 0, 1, 2, 3, 5 and 7% in weight with respect to the matrix. Ballistic tests were performed by considering three impact velocities, 130, 142 and 155 m/s by a flat-ended projectile. The results show that not only have the mechanical properties increased, but also have the energy-absorbing capability and the damage area due to addition of nanoclay particles, especially in impact velocities near to ballistic limit. For the impact velocities of 130 and 142 m/s, the maximum increase of the energy-absorbing capability is observed in 5 wt% nanoclay, whereas for the impact velocity of 155 m/s, the energy-absorbing capability is increased beyond 7 wt% nanoclay.

Hybrid polymer composites for high strain rate applications

“…For example, the compressive strength of glass/epoxy nanocomposites within the strain rate range of 400e600 s À1 has been found to increases with the addition of spherical silica nanoparticles up to 30 wt% (Tsai and Cheng, 2009). It should be noted that the improvement in mechanical properties depends on the impact velocity (Pol et al, 2013). The damage area and energy absorption in sandwich composites fabricated from glass warp-knitted fabric/epoxy skins and foam core increase with the addition of MWCNTs in the epoxy matrix.…”

Effect of 3D‐woven glass fabric and nanoparticles incorporation on impact energy absorption of GLARE composites

“…In 2012, Pol et al studied the effect of nanoclay incorporation with various weight fractions on ballistic behavior of woven fabric composites. They concluded that nanoclay particles dispersion in the matrix enhanced the mechanical properties and energy absorption capacity of woven fabric composites .…”

“…The composite materials undergo various loading conditions during their service life. The most critical condition among them is the impact loading due to the laminated nature of these structures [1]. When subjected to low or high velocity impact, the composites behavior becomes very complicated due to phenomena such as fibers breakage, delamination, dishing deformation, plugging failure, and etc.…”
