Simple Modelling of Fiber- Reinforced Plastic Composite

Simple Modelling of Fiber- Reinforced Plastic Composite

This paper describes a simple geometric model (sinusoidal model) of fibre reinforced plastic composite (FRP composite). On the basis of this model it will be presented how to obtain certain geometric parameters which fully characterize the geometry of composite structure. Using geometrical considerations it is feasible to calculate basic mechanical parameters such as Young’s modulus, very useful for further stress analysis. Such mechanical considerations and method for calculating mechanical parameters will be presented in this paper. On the basis of above mentioned theoretical considerations a special computer program was developed. The method of calculation presented in this paper can be applied to more complicated models of FRP composites.
