Behavior Of Carbon Epoxy Laminates

In the first step the nanofibrous mat was interleaved between mid layers of the laminate then mode i quasi static and cyclic loadings were conducted under load displacement condition.

Behavior of carbon epoxy laminates.

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. Monotonic tension and compression experiments are conducted on 3501 6 epoxy resin and as4 3501 6 carbon epoxy composite at temperatures ranging from room temperature to 200 c. The mechanical characterization of the laminates consists of controlled tension compression and short beam shear testing. In this study the influence applying nylon 66 nanofibers on fatigue and fracture behavior of carbon epoxy laminates is investigated.

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. 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.
