Multiscale Machinability Analysis of Natural Fiber Composites

Abstract

Machinability qualification of natural fiber composites requires a specific approach that involves the multiscale structure of natural fibers. This article addresses the machining qualification issues for natural fiber composites and proposes a new multiscale approach to analyze the topography of the machined surfaces. Results show that machining of natural fiber composites requires specific analysis scales that correspond to the natural fibrous structure size. The multiscale method can be used to improve the experimental design of natural fiber composite machining and, above all, to determine the optimum process parameters that reflect the multiscale machining characteristics of these ecofriendly materials.
