The maximum retention was obtained with CCB followed by CCA, Borax Boric and ZiBOC.

Ultrasound technique was shown to be a reliable tool for the quality assessment of timber.

It was found that holocellulose can be used as a surrogate property for determining the lignin content.

Imported timbers from various origin /country were found nondurable in exterior ground conditions and hence were recommended not to be used without treatment.

A convection heating based vacuum kiln has been developed indigenously for faster drying of timbers. A patent has been filed based on this work.

The Moisture Exclusion Effectiveness of PU showed better values than shellac and a thickness effect was observed for both finishes.

The study revealed the potential of P. deltoides in making laminated short beams.

Imported timbers tested revealed nondurable nature and complete protection could be achieved through conventional and environ-safe preservatives in the field.

Species base meant for making hockey blades has been widened with ammonia based wood bending technology. A modular and portable treatment plant has also been developed under this project.

L/P ratio is suggested to affect the flexural properties only when similar tip thicknesses are used for joining the sections

Seven fire retardant compositions were developed for the treatment of plywood and veneers that had minimum effect on glue shear strength. Plywood treated with four of these compositions passed Fire retardant and GSS test as per Indian standards.

Identification methods were developed for plantation species like Eucalyptus, Shisham and poplar.

Imported timbers tested in prototype and industrial nature cooling towers exhibited severe deterioration without treatment while they could be substantially protected with conventional and eco-friendly preservatives.

It was found that the timing of stress reversal during drying may be determined by monitoring the rate of change of shrinkage in the tangential direction.

Paper mulberry was found to be suitable for general purpose plywood and combiply with poplar and eucalyptus.

Combi LVL using poplar and Eucalyptus was successfully prepared.

A modified ultrasonic technique was shown to detect hollowness in logs and trees.

Citric acid (CA) modification was successful in achieving 20 to 65% gains in Anti Swelling Efficiency (volumetric) of Populus deltoides wood and 14.5% to 40.91 % gains in Pinus roxburghii wood. Samples modified with CA also showed protection against Fungus and termites.

A common facility center was established at FRI, where machines for basic bamboo processing were procured and housed for training and R&D for value addition of bamboo.

A schedule for drying M. composita using vacuum press drying has been developed.

It was found that nano particles can improve the physical and mechanical properties of plywood.

The earlier developed vacuum kiln has been refined for is better working.

Particle boards and fibre boards using lop and tops of M. composita are being developed.

Positive results on using lops and tops of poplar in preparing MDF indicated that dependency on solid wood can be reduced.

The study illustrated the superiority of lacquer and NC lacquer in restricting moisture entry into M. dubia wood substrate

conventional/ eco-friendly preservatives  (ZiBOC)

Melia composita, a nondurable wood could be completely protected by environ-safe preservative in ground exterior conditions.

Non conventional thermal treatments were used for durability improvement.

Post harvest fumigation technique for bamboo protection was successfully tested.

Board making through destructuring bamboo and other materials were demonstrated at TFDPC site. The final manual, work report along with study materials were also given to the funding agency.

Two components – one of training and other of R& D on value addition of bamboo were completed.

The work is under progress, training was imparted, list of machines and specifications given.

The combination ply from these species are found to meet IS standards
