INVESTIGATION OF THE DYNAMIC PROPERTIES OF ORIENTED GLASS-FIBER REINFORCED PLASTICS UNDER COMPRESSION,
Abstract
A study was done on the dynamic compressive properties of glass reinforced plastics, with an epoxy phenol resin and an ED-5 resin binder. The epoxy-phenol material had layers of glass cloth aligned longitudinally and transversely in a ratio 1 to 1; the epoxy resin had a 1 to 5 ratio. Fracture elongation and modulus of elasticity were given as functions of the logarithm of deformation rate for the (1 to 1) material aligned at 0, 22.5, and 45 degrees to the fiber direction. The tensor equations of Ashkenazi were used to relate the strength properties at a given load to the axial orientation and the axis of elastic symmetry. (Author)
