| Résumé: | In the present paper, seven laminated composites were the
subject of an experimental study to determine their mechanical
and viscoelastic properties by means of dynamic mechanical
analysis in a bending configuration. The influence
of the frequency, fiber type and fiber orientation on dynamic
mechanical properties of different system composites
were investigated. Carbon/epoxy laminates exhibit a
great stiffness when fibers are oriented along the axis of
the clamps, and the maximum modulus was reported for
unidirectional carbon/epoxy laminate [08 plies] with
56.4 GPa. The glass transition temperature was found to decrease
with the incorporation of fibers and increase with increased
frequency. For the Kevlar/epoxy laminate, an increase
of 12.5 8C in glass transition temperature was observed. This is related to a better interfacial adhesion between epoxy matrix and Kevlar fibers |
