The flexural modulus and strength of the sandwich-structured
composites significantly improved by increasing content of the
wood strands in the face layers. The effect was most pronounced
beginning with 30 wt.% the wood strands (Table 2). As compared
with the RH particleboards (control A), incorporation of 10–
40 wt.% of the strands having a high slenderness ratio in the face
layer of the composites improved the flexural modulus and
