Experimental and Numerical Investigation of Date Palm Fiber Effect on Natural Frequency of Composite Plate with Different B.Cs

Abstract

In this work, the numerical and experimental study of mechanical properties and natural frequency for composite materials reinforcement with natural fiber are presented. The experimental works included study of mechanical properties and vibration of composite materials are made of natural fiber, date Palme fiber, and polyester resin materials with different boundary conditions. And, the numerical study included evaluated the natural frequency of composite materials plate with various boundary condition and different reinforcement date Palme fiber volume fraction.The results shown the date Palme fiber causes increasing the modulus of elasticity of composite materials, then, it causes increasing the natural frequency of composite plate with increasing of fiber volume fraction. Also, the strength to weight ratio increase with using of natural fiber due to low density of natural fiber. In addition to, the vibration study included valuated the natural frequency of composite plate with various boundary conditions as (CCCC, CCFF, CCSS, CFFF and CFFF). And compare the results of vibration plate evaluated between numerical method and experimental work, that is shown the good agreement results with maximum error about (7.5%).
