Abstract

Physical and Mechanical properties in green, air dry and kiln dry conditions based upon tests conducted on small clear specimens obtained from ten logs of Bischofia javanica (Uriam) from Arunachal Pradesh have been reported. The results obtained have been compared with 'Standard Teak' (from Malabar, Nilambur and Coimbatore). Suitability indices have been reported. And compared with the coresponding values of'Standard Teak'. Expected values based on specific gravity-strength relationship have also been reported for the sake of comparison.

Abstract

A doubt has often been expressed that glue shear strength of standard quality tea-chest plywood is reduced under storage. This paper presents the results of a study to investigate the influence of storing upto about 2 years on the glue shear strength of tea-chest plywood. It has been found that upto one and half year there is very little loss of strength beyond it has gone upto 25.30°in some cases.
