Effect of Fibre Volume Fraction on Mechanical Properties of FRTP Laminates Produced by Film Stacking Method
Fiber Reinforced Plastics are now being used in all fields of industry as well as for consumer durables. In the present work, FRP laminates of glass/PP fabricated by film stacking method are studied for various mechanical properties. The glass/PP laminate of required thickness (3-4 mm) is fabricated by stacking a number of FRTP prepregs in the mould and applying heat and pressure in compression moulding press. Dynamic Mechanical Analysis, tensile, flexural and izod impact tests were performed on FRTP laminates. From DMA test, the following viscoelastic properties of GF/PP laminate were observed. (i) The storage modulus increases with increasing fibre volume fraction. (ii) The loss factor decreases with increase in volume fraction. Tensile strength and flexural strength values increase with increase in fibre volume fraction. Impact strength decreases with increase in fibre volume fraction. The results of the present study will be useful in determining the end use applications of FRTP laminates in industry.
