A Semi-Empirical Airborne Particle Erosion Model for Polyesteric Matrix Fiberglass Composites
Journal Title: INCAS BULLETIN - Year 2013, Vol 5, Issue 4
Abstract
The paper deals with the mathematical modeling of the airborne solid particle erosion rate of composite materials, in particular non-oriented fiberglass reinforced polyesteric matrices. Using the mathematical tool of non-linear regression, based on experimental data available in the state of the art, an algebraic equation has been determined to estimate the relative erosion rate of such composites. The formulation is tailored so that it relates to classical erosion models such as Finnie’s, Bitter’s or Tulsa angle dependent model which can be implemented into commercial computational fluid dynamics software. Although the implementation - per se - is not described herein, the model proposed can be useful in estimating the global effect of solid particle erosion on composite materials in this class. Further theoretical developments may add to the model the capacity to evaluate the erosion rate for a wider class of matrices as well as more types of weavings.

An Interpretation of the “Black Energy” in Universe by Using a Hydro-Dynamical Analogy with Newton Gravity
There are arguments proving that what we see now as “normal energy” (including the equivalent mass-energy) represents only 5% of the total energy of the Universe [1]. The rest is invisible meaning that no widely accepted...
