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...

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...

Bending property enhancement of wood strand composite using viscoelastic thermal compression

Creator:: Rathi, Vardan M.
Abstract:: The fundamental intent of the study was to develop an innovative wood-strand composite for use in structural applications. Plantation grown, low density, hybrid poplar was used in the study which was found to be appropriate for the underlying Viscoelastic Thermal Compression (VTC) process. Wood modified by this process has high...

The effect of elevated temperature on mechanical behavior of structural wood and wood-based composites

Creator:: Sinha, Arijit
Abstract:: Engineers, in practice, are often faced with the challenge of evaluating a fire-damaged structure and developing a rehabilitation and retrofit plan. In order to decide on a rehabilitation and retrofit plan, information on thermal degradation of building materials and connections are vital. A critical knowledge gap exists in terms of...

Supercritical fluid impregnation with biocides of wood using temperature reduction

Creator:: Kang, Sung-Mo
Abstract:: Supercritical fluid (SCF) impregnation is a promising preservative treatment method, however, the development of SCF processes has been slowed by a limited understanding of the process. Developing a better understanding of the effects of various process parameters on treatment results would allow for a more rational development of SCF impregnation....

Preparation and characterization of polymer-SiO₂ hybrids

Creator:: Ferguson, Morgan L.
Abstract:: In a search for designed materials that mimic those found in biological systems, combining polymers with inorganic materials in sol-gel chemistry processes has gained momentum in the research world since the 1990's. This work methodically investigated the properties of several related polymer-SiO₂ hybrids prepared by a simple methodology that could...

In-situ Surface Modification of Wood with Different Hot Press Platen Metallurgies

Creator:: Freitas, Shawn Robert
Abstract:: As the forest industry moves toward the use of younger trees and production of an increasing number of composite products improving durability has gained importance. Coatings are one of the most widely used methods for improving wood durability because they improve resistance to water penetration, and subsequent shrinking and swelling,...

Investigation of Eco-friendly, Bio-based Methods to Produce High Quality and Water-resistant Apple Pomace Biocomposites Using Molded Pulp Technology

Creator:: Lang, Clara V.
Abstract:: The overall goal of this study was to utilize apple pomace, the byproduct from juice processing, as a renewable source of fiber to create sustainable packaging using molded pulp technology. The goal was accomplished through two studies: 1) to modify apple pomace fibers for increasing relative cellulose composition and improving...
