Resumen:
This chapter deals on the degradation kinetics of
thermosetting matrix / fiber reinforced composites.
The diverse processes that take place during the degradation
were analyzed. It was established that the damage occurs in the matrix, in the
fibers and at the fiber/matrix interface.
The material suffers fiber corrosion, which causes the
dissolution of alkaline species around the fibers. Besides, the matrix
undergoes a hydrolysis process, and at high temperatures depending on
temperature, this can lead to microcracking caused by osmotic damage.
Degradation at the interface greatly depends on microcracking, if this happens
water absorption is significant and mechanical properties are severely
affected.
The aim of this contribution is to establish the real
processes that take place during life in service of polymeric matrix/fiber
reinforced composites materials and to determine their effect on the behavior
of such materials which is crucial for the residual life in service.
