Abstract
Tensile strength of angle ply balanced laminated made of glass fibers and epoxy matrix has been investigated under dynamic loading using an instrumented drop weight apparatus. A comparison of theoretical and experimental stress-strain curves reveals that good agreement exists for a certain range of fiber orientation. Different failure criteria have to be used for each range. Failure stresses in the dynamic case are found to be con siderably higher than the corresponding static values for the complete range of fiber orientation. Failure strains and initial effective moduli are the same for static and for impact loadings.
