Abstract
Bamboo in panel form is well suited to wood substitute can be used as furniture components. During the preparation of strips by four side planer huge amount of wastage are obtained. In the present study, Planer shavings of Bhyjja, (Bambusa vulgaris) and Borak, (Bambusa balcooa) bamboo are used for manufacturing particleboard and mat overlaid particleboard. Mitinga, (Bambusa tulda) bamboo is used for making mat. Borax-boric acid (BB) treatments were given to enhance the durability of mat. The treatment were carried out using borax-boric acid (1:1) aqueous solution of different concentrations at different time schedule by soaking process.. Retention 22.11 kg/m3 to 27.41 kg/m3 were obtained when the mat were treated with 5% and 7% BB solution for 1 to 3 days. The modulus of rupture of bamboo particle board and mat overlaid particleboard were found 16 N/ mm2 and 25 N/ mm2respectively using planer shavings of Bambusa balcooa. The modulus of rupture of bamboo particle board and mat overlaid particleboard were found 18 N/ mm2 and 26.5 N/ mm2 respectively using planer shavings of Bambusa vulgaris. It was observed that the strength properties of board made form B. vulgaris higher than that of B. balcooa . Static bending /modulus of rupture of the particleboard are satisfactory. Modulus of rupture and tensile strengths of all the boards, however, satisfy the Indian and British standards. The strength properties of the mat overlaid particle board were increased due to the use of bamboo mat in the face and back position.
