Non Technical Summary
The research under this problem will improve our understanding of wood-polymer interactions (i.e. coatings/sealants and adhesives) in a way that should decrease cost for the consumer. The idea here is that our work will lead to improved polymer component utilization in adhesives, sealants and coatings, thus less polymer will be needed to provide similar or superior properties to what is conventionally used. If we can identify key features of how different polymer components within a sealant, coating, or adhesive interact with wood (anatomical structure, cell wall structure, and wood components: cellulose, hemi-cellulose, and lignin), we might be able to tailor the component composition (or distribution) to maximize the desired wood-polymer interactions and thus properties. Other benefits include water repellent materials and fungicides derived from low value non-petroleum based forest resources, development of advanced wood-based composites and wood plastic composites, new applications for wood, and conversion of low value forest residues and fire and insect destroyed stands to value-added forest materials and feed-stocks.


Objectives Summary
FPL-4707-2 focuses on the chemical and mechanical factors that affect the properties of advanced composites. The research includes studies on traditional and non-traditional wood and wood-fiber composites, adhesive bonding of composites, chemical modification of the wood or fibers, bio-polymers for use as matrix materials, and materials, such as nano-fibers, for use as the structural component in wood-plastic composites. Research will also include engineered components such as laminated beams, composite I-beams, and structural wall panels. There are five objectives to this problem: 1) Chemical modification and property enhancement of wood based and bio-fiber resources are required to improve properties and to maximize end-use performance of advanced bio based composites, 2) Basic principles of adhesion theory for wood need to be understood to improve bonding in advanced composites, 3) Properties of adhesives must be improved to make advanced composites, 4) Bio-refining and bio-energy processes have a materials component for using byproducts from these processes to make advanced composites, and 5) Performance evaluation of advanced composites is necessary to determine the effects of various improvements in fiber properties and adhesive systems.


Approach Summary
Advanced composites will be created using a materials science approach that combines chemistry with performance property modeling. We will seek to better understand the complex interactions among the various materials used to make composites and develop technologies to chemically and physically modify wood based and other fiber resources. We will develop resins, including adhesives that are compatible with natural and modified lignocellulosic materials, processes that minimize fiber degradation during composite manufacturing, and provide improved engineered wood products. Our studies will involve modeling, development of mechanism theories, and testing those models and theories. Chemical composition (cell wall polymer content and ratios, molecular weight, reactivity, and accessibility) and fiber properties (single fiber aspect ratio, aggregate fiber properties, and individual fiber strength) of lignocellulosic fibers will be determined. This information will be used to develop an understanding of how properties of the components of a composite translate to performance of the composite.
