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.

Composite material and method for making

An aramid article is disclosed having improved resistance to penetration by sharp implements. The article is woven with tough, low denier, aramid yarns in a tight plain weave configuration; and, when used in several layers, the layers are not stitched together.
