The global motivation for this work comes from the desire to fabricate "plastic lumber" with improved mechanical properties (particularly creep resistance) from recycled plastics and wood composites. The present studies have utilized "virgin plastics" of polystyrene (PS), an amorphous, stiff material that exhibits brittle fracture, and high density polyethylene (HDPE),...
This study examined the relationship of interfacial shear strength (IFSS) and
bending strength (MOR) of several different wood-plastic composites (WPC's).
Plastics utilized were high-density polyethylene (HDPE) and polypropylene (PP).
Pine and oak were used as the wood species. Compatibilizers used included maleicanhydride
polyethylene (MAPE), polymeric methylene diphenyl diisocyanate (PMDI),
KymeneTM,...
Wood plastic composites (WPCs) are composite materials made from thermoplastic polymers, wood flour, and a small amount of process- and property-enhancing additives; they are principally used in the automotive industry and as secondary building materials. Although the WPC market is expected to keep growing, it is still relatively small when...
The tendency of wood to shrink and swell with changing moisture content remains as one of the most significant challenges to using wood in its many applications. Viscoelastic Thermal Compression (VTC) has been shown to significantly increase the density, strength and stiffness of wood. However, dimensional stability is still a...
