Behavior of Cross-Laminated Timber Diaphragm Panel-to-Panel Connections with Self-Tapping Screws

Creator:: Sullivan, Kyle
Abstract:: The goal of this project is to contribute to the development of design values for cross-laminated timber (CLT) diaphragms in the seismic load-resisting system for buildings. Monotonic and cyclic tests to determine strength and stiffness characteristics of 2.44 m (8 ft) long shear connections with common self-tapping screws were performed....

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),...

Fracture properties of balsa wood and balsa core sandwich composites

Creator:: Shir Mohammadi, Meisam
Abstract:: Favorable properties of Balsa wood make it an interesting alternative in a number of applications including thermal insulation or as a lightweight core material in sandwich composites. Increasing use in construction necessitates a better understanding of its mechanical and failure properties. In the present work, mode I and mode II...

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,...

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...

Development and characterization of new formaldehyde-free soy flour-based adhesives for making interior plywood

Creator:: Huang, Jian
Abstract:: Formaldehyde-based adhesives such as urea-formaldehyde (UF) and phenol-formaldehyde (PF) adhesives dominate the current wood adhesive market. However, these adhesives are derived from petrochemicals and carcinogenic formaldehyde. In this study, we developed two formaldehyde-free adhesives based on abundant, renewable, and inexpensive soy flour (SF). The first adhesive was mainly composed of...

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...

Morphological characterization of wood plastic composite (WPC) with advanced imaging tools : developing methodologies for reliable phase and internal damage characterization

Creator:: Wang, Yi
Abstract:: 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...

Using Acoustic Measurements and Inventory Data to Estimate Stiffness in Standing Douglas-Fir Trees

Creator:: Delgado Trejo, Jorge Luis
Abstract:: Total US lumber production in 2011 was 77.9 million cubic meters. Its primary use was for housing and construction. There is a growing concern that the structural properties for wood are being reduced as trees are harvested at much younger ages as the wood supply shifts from older to younger...

Stiffness of Douglas-fir lumber : effects of wood properties and genetics

Creator:: Vikram, Vikas
Abstract:: Wood stiffness is one of the most important properties of lumber and veneer. We studied wood stiffness (modulus of elasticity, MOE), wood density, microfibril angle, and knots in a 25 year-old wind pollinated progeny test (50 families, ~ 373 trees) of coastal Douglas-fir to understand the potential for genetically improving...
