A new solid particle erosion model for oriented fiber composite materials
Journal Title: INCAS BULLETIN - Year 2014, Vol 6, Issue 1
Abstract
The work describes a new model of erosion estimation equation which factors in both the impingement angle α and the fiber orientation angle β. Two examples of particular erosion equations are presented, for carbon fiber as well as for glass fiber in epoxidic matrix. Our methods are semi-empirical meaning that the general shape of the erosion equation is maintained while specific material coefficients must be determined for each of the matrix-fiber combination. As showed in the paper, the proposed model correlates well with the experimental data available in the literature. The work is significant since it provides a generalized method for estimating erosion rates for oriented fiber composites which can be further implemented in simulation software in a simple manner.
