Disclosed is a wood composite material comprising: wood strands disposed
in surface layers and one or more core layers, whereby an intermediate
density divides the wood strands so that the two surface layers of
strands are more dense than the intermediate density, and the one or more
core layers of the strands are less dense than the intermediate density,
and wherein the core layer contains at least about 70 wt % of the strands
that are less dense than the intermediate density; and the surface layers
contain at least about 70 wt % of the strands that are more dense than
the intermediate density.
