Characterization of GRP considering the mechanical material properties

Résumé

The absence of raw materials caused industry to search alternatives to traditional materials. In the light of this aim has emerged the concept of composite material. Therefore the realization of structures in the shipping industry and not only, using composite materials is required instead of using classical materials (ferrous and nonferrous). The present paper tries to point out that GRP composite material should be considered in numerical calculations, as an isotropic, orthotropic or anisotropic material. To determine the mechanical character of GRP composite material was used ANSYS finite element program. Taking into account the behaviour of GRP at different loads, a series of experimental modelling were made to verify the mechanical character of GRP. Numerical methodology presented in this paper was well developed and it was experimentally verified, the resulting GRP composite material behaves closer to reality when it is considered in layers in numerical modelling.
