This study was carried out for investigating the bending properties, characteristics of semi-rigid joint and screw holding strength on L-type specimmens of one com-ply(bonded with particleboard and plywood) and 15mm particle- board and 18mm particleboard. The obtained results were as follows; 1. M.O.R. and S.P.L. on bending of com-ply were higher than those of particle-board. Also M.O.E. of com-ply showed much higher than that of particleboard. 2. The results showed that the difference in bending properties between flatwise bending and edgewise bending were present. The average M.O.E.. M.O.R. and S.P.L. of flatwise loading were higher than those of edgewise loading. 3. The stiffness coefficients of the specimens constructed with two dowels were in the 10-3 level. indicative of flexible joint. And stiffness coefficients of joint type A and C were lower than that of type B. 4. The moment of joint type A and C constructed with two dowels were higher than that of joint type B. And the joint moment of comply was higher than that of particleboard. 5. Maximum screw holding strength on the face of comply was about 200% higher than that on the face of particle board.
