Abstract

Glass fiber-reinforced polymers (GFRP) are highly versatile material components that are used in a wide variety of applications. Knowing the geometries of the fibers inside such a sample is important to estimate the mechanical properties of the respective samples. We present an approach for representing fiber traces in a sparse way using arc length parametrization. Two arc length representations based on polynomials and cosine basis functions are compared. The resulting curves are evaluated in terms of their deviation from high resolution fiber traces of simulated and real data. Furthermore, the sensitivity of the parameters to small permutations is investigated to estimate their suitability in numerical optimization within our existing fiber analysis framework.
