Behavior of carbon epoxy laminates.

As4 carbon epoxy prepregs were used for fabricating test specimens and 50 different mismatch angles of fiber direction were applied on the delaminated interface of laminates. The work is aimed at improved understanding of deformation and failure mechanisms of unidirectional carbon fiber reinforced plastics. However the addition of another type of fiber modifies the mechanical behavior of the composite regarding interfacial interactions consequently affecting other properties. Although the pps matrix behavior is highly ductile at a test temperature higher than glass transition temperature it clearly appears that the decrease in the tensile properties laminates of pps based composites is much slower than the one observed in carbon epoxy laminates subjected to severe prior fire conditions.

The adoption of carbon glass fiber hybrid composites is an economical alternative to high cost carbon epoxy composites and helps to address environmental issues. In the investigation both carbon epoxy and e glass epoxy laminates are evaluated as these materials are of keen interest to the marine and undersea vehicle community. The mechanical characterization of the laminates consists of controlled tension compression and short beam shear testing.
