摘要：In this study, evaluated of the critical thermal effect caused the buckling of unidirectional and woven composite plate with different aspect ratio of plate combined from different types of long and woven reinforcement fiber and different resin material types. The thermal buckling analysis by using theoretical analysis with solution the general equation of motion of orthotropic composite simply supported plate with buckling thermal effect and evaluated the effect of reinforcement type and resin types on the buckling temperature with effect of volume fraction of reinforcement fiber and resin materials. In addition to, analysis the problem of thermal buckling by numerical study with using finite element method and compare the results of numerical analysis with theoretical results of thermal bucking plate and evaluated the agreement between the two methods used. The results are the critical thermal buckling temperature of orthotropic composite plate with effect of different reinforcement fiber as unidirectional or woven fiber and different resin materials with various volume fraction of reinforcement fiber and effect of aspect ratio of composite plate and compare of critical temperature with different reinforcement types. In addition to compare between the theoretical and numerical analysis and evaluated the maximum percent error about (3.5%). And, the results showed that the critical temperature buckling of unidirectional reinforcement fiber more than critical bucking temperature of woven reinforcement fiber and the buckling temperature increasing with increase the volume fraction of reinforcement fiber .
