Wood Processing Division

Background

Wood Processing (WP) Division has been working to find appropriate technologies for value addition to non-durable timbers from plantations and other secondary timbers. These include studies on drying behavior and finding appropriate seasoning techniques for plantation grown timbers, permeability of wood, development and assessment of wood preservatives and their treatment techniques, techniques for overcoming residual growth stresses in logs, chemical modification of wood, weathering of wood and its protection, and development of wood polymer composites.

Goal

To develop technologies for value addition to non-durable timbers from plantations and other secondary timbers

Thrust Areas

  • Wood drying technologies and development of seasoning schedules for lesser known and plantation species.
  • Development and assessment of preservatives under terrestrial and marine conditions.
  • Studies on growth stresses in plantation timbers.
  • Weathering of wood and its protection.
  • Chemical modification of wood.
  • Wood polymer composites.

Research Activities

Ongoing Research Programmes
Currently we are running following research projects

  • Effect of particle size on properties of wood filled polypropylene composites
  • Studies on influence of microwave treatment on drying characteristics and treatability of wood.
  • Studies on durability of treated and untreated timbers of selected species.
  • Performance of coatings on modified wood surfaces.
  • Study on the morphology and properties of natural fiber filled polypropylene composites (NFPPC).
  • Studies on the permeability of selected imported timbers marketed in Karnataka.
