composed of a particle- 

 board core between layers 

 of veneer, and other sand- 

 wich materials of wood with 

 metal or plastic. New prod- 

 ucts such as resin-treated 

 papers and densified prod- 

 ucts called "compreg" and 

 "impreg" also have been 

 produced and have proved 

 important for military and 

 other purposes. 



Early work on wood preser- 

 vation was soon expanded 

 at the Madison laboratory 

 and at other institutions 

 such as Mississippi State 

 to include fundmental 

 studies of chemical, physi- 

 cal, and toxic qualities of 

 various preservatives, and 

 ways of improving preserva- 

 tives and treating process- 

 es. Greater efficiency in the 

 wood-preserving industry 

 and ways of adjusting to 

 environmental regulations 

 have been important bene- 

 fits of this research. Related 

 studies of the flammability 

 of different woods treated 

 with fire-retardant chemicals 

 also helped improve wood- 

 treating processes. Re- 

 search on paints and 

 painting methods has 

 provided knowledge that 

 resulted in better perfor- 

 mance of wood in construc- 



tion and savings in timber 

 resources and consumer 

 dollars. 



Engineering research and 

 development relating to 

 logging and manufacture of 

 wood products likewise 

 produced much new tech- 

 nology and improved equip- 

 ment. For example, a coop- 

 erative project involving the 

 Georgia Pacific Company, 

 Auburn University, and 

 equipment manufacturers 

 led to development of 

 machines for chipping trees 

 in the woods. Other compa- 

 nies, such as International 

 Paper, working with equip- 

 ment manufacturers did 

 much to develop pulpwood 

 and tree harvesters. 



The information developed 

 through such utilization 

 research has heen issued 

 in many publications, includ- 

 ing a major work by Peter 

 Koch on utilization of the 

 southern pines (1972). In 

 1978 a symposium on 

 complete tree utilization of 

 southern pines also provid- 

 ed much useful information 

 on the latest developments 

 in various aspects of south- 

 ern pine timber utilization 

 (McMillin 1978).
