The report discusses a study to determine the effect of test variables on the strength of unidirectional composites. Specimens of glass fiber reinforced epoxy of varying geometry were tested in tension and flexure at several strain rates. Both experi

Crack growth resistance values are measured at three loading rates for blends of Nylon 6 and ABS with varying levels of compatibilizer using the generalized locus method [14]. Load against load point deflection curves are obtained at loading rates of

The influence of compatibilizer on the morphology and mechanical properties of a blend of nylon 6 and ABS has been studied. For this blend, the morphological domain size decreases significantly with increasing compatibilizer level. However, stiffness

The stress-strain behavior of glass bead filled polystyrene, styrene- acrylonitrile, ABS, and PPO composites is studied at various temperatures below their glass transition temperature. Earlier studies of bead filled composites indicated that the add

The structural utility of short, glass fiber-reinforced epoxy composities is experimentally investigated for fiber volume fractions from 0.15 to 0.5. The strength and stiffness of systems with randomly oriented fibers are compared with those of simil

The flexural fatigue characteristics of boron fiber reinforced epoxy were shown to be strongly dependent on the aspect ratio of the reinforcing fibers. These composites were evaluated in a stiffness limited, constant maximum stress mode. The failure

The mechanical performance of fiber glass epoxy, cross-plied laminates having either ductile or brittle matrices, was evaluated in tension. The laminates with ductile matrices have higher initial strength, slower crack propagation in the transverse l

A technique is presented which, by means of plating and etching processes, permits the creation of a wide variety of crack propagation gauges. High precision gauges of arbitrary size and shape are easily prepared. Specific gauge configurations are sh

Experimental evidence is presented for transversely isotropic glass- epoxy to show that shear strength determinations using the short-beam shear method (ASTM D2344-67) AGREE WELL WITH THE RESULTS OF TUBE TORSION FOR A CERTAIN VOLUME FRACTION RANGE. I
