Free Vibration Characteristics of Phoenix Sp Fiber Reinforced Polymer Matrix Composite Beams

In recent days the use of natural fiber reinforced polymer composites in automobile, aerospace and other industrial applications becomes increased due to light weight, less cost, bio degradability and easy to manufacture. It becomes necessary to know the dynamic behavior of natural fiber reinforced composites to use it effectively for engineering applications. This paper presents the free vibration characteristics of newly identified Phoenix Sp fiber reinforced polymer matrix composite beams, moreover the physical, chemical and mechanical properties of fiber was determined by using standard experimental methods. The modal analysis is carried out on composite beams having different fiber gauge lengths such as 10 mm, 20 mm, 30 mm, 40 mm and 50 mm. The Clamped-Free (CF) boundary condition is used for the analysis. The composite beam with 30 mm fiber length has maximum natural frequency with less amplitude; hence it is suggested for industrial applications.
