The effects of extractives and compatibilizers on the flexural properties of natural fiber-thermoplastic composites

Creator:: Saputra, Hartono A.
Abstract:: Natural fibers such as wood, flax, and hemp are frequently used as fillers in natural fiber-plastic composites (NFPCs). At present, wood fiber is the most commonly used filler in the production of wood-plastic composites (WPCs). The advantages of these fibers compared to conventional inorganic fibers such as glass fiber is...

An experimental study on tensile properties of cellulose nanocrystal reinforced epoxy nanocomposite material

Creator:: Zeng, Jin
Abstract:: Epoxy resin is a thermosetting resin that is commonly used as composite matrix. Epoxy composite materials are well utilized in industries, such as aerospace, due to their good mechanical properties. Nano-scale filler reinforced polymer composite materials have been intensively researched in recent decades. Cellulose nanocrystals (CNXLs) are a type of...

Hygro-mechanical response of clear softwood specimens to compression under cyclic climate

Creator:: Guo, Ning
Abstract:: Hygro-mechanical effect is a general term applied to all phenomena that involves interaction between moisture content and mechanical characteristics of hygroscopic materials by analogy to thermo-mechanical effects. The hygromechanical effects include (but are not limited to) free shrinkage/swelling, effect of moisture on elastic modulus, strength, creep, failure mechanisms, and mechano...

Improving wood strength and stiffness through viscoelastic thermal compression

Creator:: O'Connor, John P.
Abstract:: The objective of this research project was to increase the density, strength, and stiffness of two low to medium-density diffuse-porous hardwood species. Wood used in this study was processed using a method of wood densification known as “Viscoelastic Thermal Compression” (VTC). The VTC process is a three phase treatment which...

Dilute solution molecular characterization and drag reducation studies of high molecular weight polyethylene oxide

Creator:: Jones, Brian Dion
Abstract:: The molecular weight distributions of two high molecular weight (M[subscript w]>>1 million) polyethylene polymers, WSR-308 and WSR-301, were characterized with gel permeation chromatography (GPC) coupled with a multi-angle laser light scattering detector (MALLS). The M[subscript w] of the WSR-308 was found to be 5.10x10⁶ g/mol with a molecular weight range...

Including wood stiffness in tree improvement of coastal Douglas-fir in the US Pacific Northwest: a literature review and synthesis

Creator:: Jayawickrama, K. J. S., Ye, T. Z., Gupta, R., and Cherry, M. L.
Resource Type:: Technical Report

Sex differences in vertebral bone characteristic, loading patterns and the factor of risk in prepubertal children

Creator:: Fuller, Arwen A.
Abstract:: Sex differences in bone mass and size are thought to contribute to the greater incidence of vertebral fractures in women. While these sex differences are widely recognized, the relative contributions of bone mass, bone density, and bone size to the differences in vertebral strength and fracture risk between men and...
Resource Type:: Masters Thesis
Full Text:: matched for age, height, weight and vertebral height, the mechanical stress on the vertebra is greater in

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,...
