Quasi-static, low-velocity impact (LVI) and ballistic impact loading conditions were used to find the material properties and dynamic responses of E-glass/phenolic composites. Standard American Society for Testing and Materials (ASTM) tests were used to find the density, Poisson's ratio, tensile, compressive and shear strengths, and the elastic and shear moduli of the material. The quasi-static punch shear and crush strength tests were used to find the punch shear and crush strengths of the material. LVI tests were conducted to obtain force versus time curves for various loading conditions. Ballistic testing was conducted using a right circular cylinder (RCC) to find the V-50 ballistic limit and the depth of penetration of the RCC at various impact velocities. The experimental results of this investigation can be used for structural design and to validate numerical solutions for both LVI and ballistic impact events.
