CFRP is being used in the research of lightweight components and materials in many industries such as aerospace and automotive industries. The CFRP has a number of advantages of the specify strength, specify rigidity, low thermal deformation, corrosion resistance, and vibration attenuation properties.
It is difficult to find the exact physical properties as theories because the CFRPs are varied for mechanical properties in accordance with the change of the number of stacked layers of the material striking the directional angle and laminated.
It seems that obtaining the physical properties of metal is sufficient tension test. However, in the case of the CFRPs, this should be tensile, compression and shear based on experimental basic tests. In addition, laminate methods is time consuming and costly in order to obtain the physical properties because of the way through the laminate to individually test each time such a change (for example, number of layers, the fiber array angle, etc.) and to utilize the simulation technique to predict a change in the physical property data of the CFRP lamination angle test piece for solving these problems.
On this study, the finite element analysis could predict and obtain the physical properties of the carbon fibers and the resin even if the carbon fiber laminate and the number of modified stacking angle are mixed. It verifies the reliability in comparison with the simulation result and the actual test results to predicted physical properties of the carbon fibers and the resin.
And the graphs are plotted on stacking angles in order to predict the strength and modulus of elasticity according to the change in the number of stacking and changing angle. Conclusions obtained from this study are as follows.
