how to stiffen wood plastic composites

Formula & tooling considerations for manufacturing with wood .

The percentage of wood will also have a bearing on the strength and stiffness of the final product. Generally speaking, the more wood that's added, the stiffer the product becomes. Wood can make up as much as 70 percent of the total wood-plastic composite, but the resulting stiffness comes at the expense of the ductility of..
