| description.abstract | The mechanical performance of a composite material is decisively controlled by
the state of fiber-matrix interface or interphase. Its properties influence the
integrity of composite behavior because of its role in transferring stress between
the fiber and the matrix. The factors affecting the interface are too complex to be
precisely concluded. Fibrous composites are increasingly being used in many
casual as well as critical applications owing to various desirable properties
including high specific strength, high specific stiffness and
controlled anisotropy. But unfortunately polymeric composites are susceptible to
heat and moisture when operating in changing environmental conditions. They
absorb moisture in humid environments and undergo dilatational expansion. The
presence of moisture and stresses associated with moisture-induced expansion
may cause lowered damage tolerance and structural durability. The structural
integrity and life time performance of fibrous polymeric composites are strongly
dependent on the stability of the fiber/polymer interfacial region. The low
molecular weight impurities may migrate from the bulk of the adhesive to form a
weak boundary layer at or near the fiber surface. The active carbon fiber surface
can strongly attract polar molecules of the polymer matrix. This may develop a
boundary layer of high cross-link density. This micro-structural gradient at the
interface may promote crack initiation and propagation through this layer. The
environmental and experimental variations, such as moisture, temperature and
variation of loading rate can limit the usefulness of polymer composites by deteriorating
mechanical properties during service. | en |
