“…It is noted that UHMWPE tapes [31,32], manufactured under the trade names Tensylon ® by DuPont and more recently grade BT10 Dyneema ® by DSM, offer a means to compare laminates with similar compressive strengths but with different ply tensile strengths. Even though the tensile strength of the tape materials is substantially less than that of the fiber-based materials, their out of plane compressive strengths are similar to the fiber based grades of these materials.…”

A B S T R A C TThe mechanisms of progressive penetration for two ultrahigh molecular weight polyethylene (UHMWPE) reinforced laminates have been investigated. One used an UHMWPE fiber reinforcement while the other utilized molecularly aligned tape. Both materials had similar out of plane compressive strengths, but the fiber system had a 40% higher in plane tensile strength than the tape. Laminated, 6 mm thick plates with a [0°/90°] ply architecture were impacted by a 12.7 mm diameter sphere under conditions that either allowed out of plane plate deflection or eliminated this deflection by rear support of the target. The depth of penetration and the ballistic limit in the rear-supported tests were identical for the two materials, and proceeded by progressive ply failure. However, tests in the edge clamped condition resulted in a substantially higher penetration resistance, especially for the higher tensile strength fiber-reinforced material. Edge clamped testing of a bilayer target, where the front third was composed of the tape material and the remainder comprised fiber reinforced laminate, had the same ballistic limit as a target composed of only the higher ply tensile strength fiber reinforced material. Penetration in both test support conditions was discovered to occur by tensile ply rupture under the projectile, consistent with a recently proposed mechanism for converting out of plane compression to in plane ply tension. Lateral displacement of plies was also observed near the sides of impact craters in both materials, indicating the existence of a second mechanism impeding penetration of the spherical shaped projectile.

“…The method utilizes only one starting material, a highly oriented fiber or tape, to make homocomposites in a two-stage process: soaking and compacting. They have studied the systems of melt-spun PE, gelspun PE, PET, PP, and Vectran® LCP fibers (30)(31)(32)(33)(34)(35)(36)(37)(38)(39). Meanwhile, a parallel study conducted by Farris et al at University of Massachusetts has developed a similar process.…”

A novel process called high-temperature high-pressure sintering coupled with thermoforming was studied and explored to make shapeable matrix free composites by consolidating and molding layers of ultra high molecular weight polyethylene (UHMWPE) fabric at an elevated temperature under pressure. The optimal processing temperature was found to be near the fiber's melting point (150°C). The Process-Structure-Property relationship was investigated to give an in-depth and better understanding of this creative process. Compared to other UHMWPE fiber materials, Spectra ® cloth is shown to be the best material to use this process and make ballistic shields and other high performance products.

“…The alternative method to quantify the damage in composite is the energy method [5][6][7][8][9][10][11] . In this method the energy absorbed in different damage mechanisms have been quantified and based on the energy calculations the residual velocity and ballistic limit have been calculated.…”

“…In this method the energy absorbed in different damage mechanisms have been quantified and based on the energy calculations the residual velocity and ballistic limit have been calculated. Morye [5][6] , et al have studied that in addition to the two major energy absorbing mechanisms namely tensile failure of fibers and elastic deformation of the composites, the energy absorption in the form of kinetic energy of the moving cone also plays a major role. …”

Glass/epoxy composite laminates are subjected to impact loading and the energy absorbing capacity of the laminates is studied. In the present study, laminates with four different orientations and thickness values are considered. Analytical study is carried out based on energy method and results are compared with FE results obtained from Abaqus/Explicit software. Results obtained from the analytical methods are showing good agreement with the FE results. It is found that cross-ply laminates are most efficient in ballistic resistance when compared with the laminates of other orientations. It is also noticed that the energy absorbing capacity is decreasing with increase in velocity of the projectile for a given lay-up and thickness value.
