Out-of-plane failure mechanisms in LFRP composite cutting
Abstract
. LFRP (Long Fiber Reinforced) composites are widely used in structural components for high responsibility
applications in different industrial sectors. Composite components are manufactured near final shape,
however several machining operations are commonly required to achieve dimensional and assembly
specifications. Machining should be carefully carried out in order to avoid workpiece damage. Despite
of the interest of numerical modeling to analyze in detail the phenomena involved during composite cutting,
there are only few works in the scientific literature dealing with this topic even in the simple case of
orthogonal cutting. Out-of-plane failure can be accounted only if three dimensional modeling is performed.
However up to date numerical analysis of cutting found in scientific literature was focused in
two-dimensional approach. In this paper (2D) and three dimensional (3D) numerical modeling of orthogonal
cutting of carbon LFRP composite are presented. The aim of the paper is to analyze the complex
aspects involved during cutting, including out-of-plane failure.
