Estimation of Effective Elastic Design Parameters of Uni-directional Continuous FRP Lamina for Variable Fiber Volume Ratios Using Micromechanical Models

Abstract

Composites made of fiber-reinforced polymers are a significant class of technical materials nowadays. They are easily made, offer exceptional mechanical qualities, and a distinctively flexible design. Compared to conventional materials, FRPs provide greater strength while reducing weight. Fiber-reinforced polymer (FRP) composites are increasingly being employed as important structural components in a variety of industries, including aerospace, automotive, bridge construction, and oil and gas pipeline construction. The sensitivity of FRPs to experimental variation makes it a lot more complicated system, yet empirical relations can readily assess it using empirical models. The mathematical relations obtained without any derivation are referred to as these models. The mechanical properties of FRP composite structures under unidirectional loading circumstances were the main focus of this investigation. Fibre volume fraction, layer geometry, fiber/matrix characteristics, matrix type, and fibre orientation are some of the variables that can be changed to change these mechanical properties. Only the variation in the fibre volume fraction from 40 to 60 percent is used to validate the results in this case. Additionally, the optimum model for assessing the composite elastic characteristics is recognized, and the differences between the models' attributes are recorded.
