  Abstract

The influence of interphase on the tensile property of composite is examined in the present study. For this, fabrication of composite (FOC) is carried out using natural fibers: bamboo fiber and jute fiber and polyester resin as per the hand layup technique. The fibers are arranged in a longitudinal direction with varying the volume fraction of fiber (vf). The tensile testing of fibers, polyester and composites are held on the universal testing machine (UTM) and evaluated experimental tensile properties: tensile strength (TS) and elastic modulus (E). The mathematical models are proposed to measure the influence of interphase on the longitudinal elastic modulus of composite (Ecl) for longitudinally placed unidirectional fiber-reinforced polymer composites (LUDFPC) with varying interphase volume fraction (vi). The different interphase property variations: linear variation, hyperbolic variation, parabolic variation, powerlaw variation and exponential are considered in the modeling of composite and measure its effect on Ecl. The comparative study of proposed models with other researchers models is carried out. The validation of developed models is carried out using other researchers experimental data. The present study signifies the important outcome as vi should be around 15 % to 20 % of vf to predict Ecl; Parabolic variation is recommended for the prediction of Ecl.
