  1. Fatigue response of notched graphite--epoxy laminates

    Kress, Gerald R.Virginia Polytechnic Institute and State University1983

    … and strength of notched quasi-isotropic graphite-epoxy laminates were recorded and related to the fatigue damage. Two different laminates [0,90,+45,-45]s (type A) and [ +45, 90, -45, 0] s (type B) were considered and the effects of stacking sequence were compared. Nondestructive testing techniques …

  4. Accelerated viscoelastic characterization of T300/5208 graphite- epoxy laminates

    Tuttle, M. E.Virginia Polytechnic Institute and State University1984

    … viscoelastic response of polymer-based composite laminates, which may take years to develop in service, must be anticipated and accommodated at the design stage. Accelerated testing is therefore required to allow long-term compliance predictions for composite laminates of arbitrary layup, based …

  5. Multi-axial fracture behaviour of notched carbon-fibre/epoxy laminates

    Tan, Julian Lip YiUniversity of Cambridge2015

    Carbon-fibre reinforced polymer (CFRP) laminates are widely used in various engineering applications, such as in race cars and aircrafts, because they are light, stiff and strong. They commonly contain stress raisers in the form of holes and notches (for mechanical joining methods, routing of pipes …

  11. Effect of ply drop-offs on the strength of graphite-epoxy laminates

    Curry, James M.Virginia Polytechnic Institute and State University1986

    The strength reduction of a graphite-epoxy laminate due to dropping plies is investigated experimentally and analytically. Laminates were tested under uniaxial tension and compression. All the laminates were flat on one side with the plies dropped from the middle of a [( ± 45/0/90)<sub>s</sub> …

    Hess, Christopher D.

    <p>Low energy impact damage to a composite structure is difficult to detect and can have profound effects on compressive strengths. Low energy impact damage is sometimes termed as barely visible impact damage (BVID). Detecting BVID is only possible by implementing nondestructive testing (NDT) …
