Abstract:

In order to analyze the effects of different core materials on the compression resistance of the O-shaped core reinforced composites, the mechanical responses of three dinds of corematerials of resin core and glass-fiber core as well as metal core reinforced composites under the same compression action were compared by the calculation using finite element analysis (FEA). By comparatively and analyzing indexes of deflection-time curves, weight, stress distribution, and equilibrium degree of stress, it was found that both of the stress distribution symmetry and loading equilibrium were beneficial to the loading-bearing performance of the materials, even which can absorb more energy and generates relatively-smslldeformation. Furthermore, taking the requirements of compression resistance, loading equilibrium and light-weight into consideration, the glass-fiber core reinforced composite should be selected instead of resin or metal core reinforced composites.
