Non Technical Summary
The focus of this problem is to understand the performance of bonded, modified, and coated wood products and other wood-containing products by examining the performance from product performance aspects. These include the properties of the individual materials, including wood, adhesives, sealants, and coatings, as well as the assembled product. To successfully compete with non-wood and to effectively use our natural forest resources, improved wood products need to be developed.


Objectives Summary
The use of unaltered wood continues to decrease as it is replaced by treated wood, bonded wood, wood composites, engineered wood, and coated wood. The focus of this problem is to understand the performance of bonded, modified, and coated wood products and other wood-containing products by examining the performance from product performance aspects. These include the properties of the individual materials, including wood, adhesives, sealants, and coatings, as well as the assembled product. While Problem 2 investigates wood at cellular level (generally 1 to 100 um) and Problem 3 examines material at the nano level (below 100 nm), this problem investigates the properties of materials at the macro level, generally above 1 mm. Thus, nanoscale evaluation of properties falls in Problem 3, but the use of nanoparticles or nanotechnology to make products and test the bulk properties of these products falls in this problem area.


Approach Summary
Widely varied.
