Abstract

Wood plastic composites
are an interesting development in composite materials. They have gained wide
market interest recently because of their sustainable material sources and
beneficial material properties. Because thermosets or thermoplastics are
involved in the composites, the material is very temperature-dependent and
suspect to considerable dimensional changes at different temperatures. To minimize
waste generation and enable reheated material post-processing, the distortion
and displacement of the composite material has to be controlled precisely in
different temperature ranges. This article studies ways to control this
displacement and proposes a solution with an odometer and polynomial curve fit.
