Development and evaluation of novel coupling agents for kenaf-fiber-reinforced unsaturated polyester composites

Creator:

Ren, Xiaofeng

Abstract:

Natural fibers are gaining popularity as reinforcement materials for thermoset resins over the last two decades. Natural fibers are inexpensive, abundant, renewable and environmentally friendly. Kenaf fibers are one of the natural fibers that can potentially be used for reinforcing unsaturated polyester (UPE). As a polymer matrix, UPE enjoys a...

Development and evaluation of a new formaldehyde-free wood adhesive from renewable materials for making interior plywood

Creator:

Jang, Yonghwan

Abstract:

Synthetic adhesives, such as phenol-formaldehyde (PF) resins and urea-formaldehyde (UF) resins, have dominated the wood adhesive market since they were introduced in the wood products industry. Formaldehyde, as a key component in the manufacturing of PF and UF resins, has been classified as a known human carcinogen by the International...

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...

Environmental effects on heartwood extractive content and their consequences for natural durability in Douglas-fir and western redcedar

Creator:

Taylor, Adam McVaugh, 1969-

Abstract:

Heartwood can have properties that are distinct from sapwood, including resistance to insect and microbial attack. Despite the practical importance of heartwood formation in trees, a review of the literature revealed that little was known about the effects of environmental factors on heartwood quality or how variations in heartwood properties...

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...

Cellulose reinforced high density polyethylene

Creator:

Palaniyandi, Velmurugan

Abstract:

High density polyethylene (HDPE) is a ubiquitous material with versatile properties. It is produced and used in greater volume than any other thermoplastic. HDPE is often filled with a variety of materials for various applications. Glass fiber and wood flour are two common fillers for HDPE. Recently there has been...

Wood quality studies in second-growth western redcedar (Thuja plicata Donn.)

Creator:

DeBell, Jeffrey D.

Abstract:

Western redcedar (Thuja plicata Donn.) is a valuable commercial species found in the northwestern United States and southwestern Canada. This dissertation includes four papers focused on wood and stem characteristics of second-growth western redcedar, and how those characteristics vary within the stem or how they are influenced by cultural practices....

New application of crystalline cellulose in rubber composites

Creator:

Bai, Wen

Abstract:

Rubber without reinforcement has limited applications. The strength of reinforced rubber composites can be ten times stronger than that of unreinforced rubbers. Therefore, rubber composites are widely used in various applications ranging from automobile tires to seals, valves, and gaskets because of their excellent mechanical elastic properties. Silica and carbon...

Reactive polyphenols and dissolved nutrients in a nitrogen-limited headwater catchment, western Cascades, Oregon, USA

Creator:

Rasmussen, Janet K.

Abstract:

In undisturbed N-limited forested catchments, DON may represent over 90% of the total N lost in streams. Some ecologists have suggested that plant-derived reactive polyphenols may be responsible for DON binding and transport because polyphenol-protein complexes are known to precipitate out of solution, bind to mineral surfaces or organic matter...

Agroforestry farming in American Samoa : a classification and assessment

Creator:

Tuitele-Lewis, Jeannette D.

Abstract:

Agroforestry is a traditional farming practice in American Samoa that has helped to sustain the livelihood of the native population for centuries. These once self-sufficient islands have become economically dependent on U.S monies and other external resources during the past century. Dependency has caused a shift in the carrying capacity...
