Abstract

In the aeronautical/aerospace structural design the increasing demands of materials having highmechanical performance, has led to the a wide use of Polymeric Matrix Composites (PMCs) mainlyreinforced by carbon fibers (Carbon Fiber Reinforced Plastics, CFRP). The main drawbacks in the useof such composites are due to high sensitivity to environmental features and low workingtemperatures; moreover, these materials do not tolerate the fire exposure because of the inflammabilityof both the matrix and the fibers.In order to develop a composite that combines the structural performance of CFRP with a goodstrength to high temperatures and fire, in the present work the use of a hybrid composite consisting ofa CFRP laminate joined to proper layers of ceramic matrix composite (CMC), has been investigated.Preliminary experimental tests carried out to assess the numerical model, and subsequent mechanicaland thermal numerical simulations, have corroborated the reliability of the hybrid composite proposed.
