    Notes: Abstract 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 5 mm min−1 and 500 mm min−1 using a tensile testing machine. An instrumented drop weight impact testing machine is used to obtain data at a loading rate of 1.2×105 mm min−1. Dynamic effects can be considered negligible for the three testing speeds used and the effects of these speeds on crack growth resistance values can be observed. The results of these tests help determine the optimum compatibilizer level for high rate loading applications.

    Notes: Abstract 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 and tensile stress at yield are unaffected by these changes. Within the range of these experiments, lzod impact strength increases monotonically with increasing levels of compatibilizer, but the resistance to crack initiation (J c ) and the resistance to steady state crack growth (R p ) are both increased by the addition of a small amount of compatibilizer and are essentially independent of further increases.

    Strength of short-fiber reinforced composites (1972)

    Notes: 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 similar composites with aligned fibers. The ultimate strength of both types of material increses in a reasonably linear fashion with volume fraction up to 0.5. For all volume fractions in this range, strength of the random composites is slightly higher than the longitudinal and much higher than the transverse strength of equivalent compsites with aligned fibers. The modulus of the random system is approximately two-thirds the longitudinal and twice the transverse modulus of the unidirectional material. The structural utility of the flow molded material is greatest in uniaxial, stiffness critical situations. The greater strength and planar isotropy of the random composites make them preferable in all strength limited or multiaxial applications.

    The effect of aspect ratio on the fatigue life of short boron fiber reinforced composites (1969)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: 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 mechanism was found to be a combination of interfacial failure and brittle rupture of the matrix at 45 deg to the axis of the fibers. These fatigue cracks result in debonding of the outer fibers, thereby reducing the effective moment of inertia of the specimen.

    The mechanical performance of cross-plied composites (1971)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: 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 layers and higher ultimate stress and strain. In both the ductile and brittle systems, the laminae have higher strength, stiffness and toughness than equivalent unidirectional composites. This improved performance results from the interaction between the perpendicular layers which gives them additional stiffness due to shear and transverse coupling effects and also increases the resistance of each individual layer to crack propagation and plastic flow.

    A deformational mechanism in particulate-filled glassy polymers (1973)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 17 (1973), S. 1173-1185

    Notes: The stress-strain behavior of glass bead-filled polystyrene, styrene-acrylonitrile, styrene-acrylonitrile-butadiene, and polyphenylene oxide composites is studied at various temperatures below their glass transition temperature. Earlier studies of bead-filled composites indicated that the addition of filler decreases toughness and ultimate elongation. Our results show that while this is true for certain conditions, it is also possible for such composites to have higher toughness and ultimate elongation than the unfilled matrices. A deformational mechanism, involving crazing of the matrix, is proposed which explains this behavior.
