Abstract

The current work covered the investigation of the effect of powder reinforcement on the buckling load of orthotropic hyper composite plate composed from powder and unidirectional or woven reinforcement and resin materials . An analytical solution has been suggested to evaluate the buckling load of orthotropic hyper composite plate. The general equations of properties of hyper composite plates have been presented taking into consideration the effect of powder reinforcement and unidirectional of woven and resin materials. The finite element method using Ansys Package Ver. 14 was employed. The comparison has shown a good agreement with a maximum discrepancy of ( 1.9% ). The results cover the determination of buckling load of simply supported orthotropic hyper composite plates manufactured from powder reinforcement and unidirectional or woven fiber and resin materials with different volume fractions. Also ,the results showed that the buckling load of the plate is increasing with the increase the reinforcement powder and slightly affected by the powder reinforcement types. Also, it has been shown that the buckling load increases with the increase the unidirectional or woven reinforcement fiber is more than the increase in the buckling load of composite with the increase of powder reinforcement.
