Abstract

This experimental project is an investigation of the mechanical properties of Rubberwood (hevea brasiliensis) Laminated Veneer Lumber (LVL). LVL is a product recently developed to substitute solid wood in an engineered form. Three common mechanical properties have been studied, i.e. static bending, compression parallel to grain and tension parallel to grain. The test method was based on ASTM (D-198). For each test specimens, basic stress, maximum load, maximum displacement and failure mode were observed. Experimented results show that basic compression stress value is 35.00 N/mm² for rubberwood LVL and 29.91 N/mm² for solid rubberwood. For basic tension stress, rubberwood LVL and solid rubberwood achieved 29.59 N/mm² and 59.61 N/mm². While in three point bending test, basic bending stress for rubberwood LVL is 53.18 N/mm² and 44.62 N/mm² for solid rubberwood. From the results, it is found that rubberwood LVL is stronger than solid rubberwood in compression parallel to grain and bending properties but it is weak in tension parallel to grain condition. The information gained in this research hopefully can make contribution in determining the suitability of rubberwood LVL in structural propose and development of rubberwood LVL product especially in Malaysia.
