Sinusoidal Model of Fiber-reinforced Plastic Composite

ABSTRACT: This article describes a simple geometrical model of fiber-reinforced plastic (FRP) composite. On the basis of this model it will be presented how to obtain certain geometrical parameters, which fully characterize the geometry of composite structure. Using geometrical considerations it is possible to obtain from this model basic mechanical parameters very useful for further strength analysis. Such mechanical considerations and method for calculating mechanical parameters will be presented in future article. On the basis of above mentioned theoretical considerations a special computer program was developed. The method of calculation presented in this article can be applied to more complicated models of FRP composites.
