Abstract
This invention relates to an improved method for making composite structures by dispersing a high tenacity fiber such as aramid in a polymeric matrix to form a premix, combining the premix with a natural fiber such as wood flour and extruding the resulting mixture through a fiber alignment plate and die such that the fibers are substantially aligned in the flow direction of the extrudate.
