Determining fracture toughness by orthogonal cutting of polyethylene and wood-polyethylene composites

Creator:: Semrick, Kalin
Abstract:: The purpose of this thesis was to evaluate orthogonal cutting as a method to determine the fracture toughness of low and high density polyethylene and wood plastic composites. A test fixture was developed to capture normal and tangential cutting forces at variable depth and rake angle. A tool interface method...

Development of an Accelerated Method for Assessing Decay of Wood Plastic Composites (WPC's)

Creator:: Silva Guzman, Jose Antonio
Abstract:: This study examined the decay resistance of the pine and maple components of wood plastic composites (WPC' s) of varying thicknesses exposed on several culture media to wood decay fungi under laboratory conditions. The ability of malt agar extract (MEA), potato dextrose agar (PDA), amended basal salts, sawdust (maple and...

Investigation of new compatibilizer systems for wood-polyethylene composites

Creator:: Geng, Yu
Abstract:: Wood-plastic composites (WPCs) are one of the fastest-growing sectors of the wood composites industry. However, the strengths of WPCs are typically low because of the poor interfacial adhesion between hydrophilic wood and hydrophobic thermoplastics. A compatibilizer that can form bridges between wood and plastics is required to give WPCs desirable...

Improved interfacial adhesion in wood-plastic composites : Development of new compatibilizers

Creator:: Zhang, Cheng
Abstract:: In wood-plastic composites (WPCs) a compatibilizer is often used to improve the interfacial adhesion between the hydrophilic wood filler and the hydrophobic plastic matrix. At present, while the basic concepts of compatibilization are understood, the optimized chemical structures of an effective compatibilizer, including the ideal structures of the wood-binding domain...

Chemical modification of wood : dimensional stabilization of viscoelastic thermal compressed wood

Creator:: Gabrielli, Christopher P.
Abstract:: 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...

Studies of polystyrene (PS) high density polyethylene (HDPE) and PS/HDPE/wood composites from an extrusion process : mechanical properties, rheological characterization and morphology

Creator:: Xu, Bin
Abstract:: 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),...

Interfacial shear strength of wood-plastic composites

Creator:: Rogers, James F.
Abstract:: 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,...
