Tensile Strength Analysis of bamboo and Layered Laminate Bamboo composites

Tensile properties of bamboo laminae, prepared from bamboo slivers, selected from different regions of bamboo culms (Dendrocalamus strictus), increases from inner to outer region for any cross section and the same is experienced from bottom to top. Application of rule of mixture, on linear regression line drawn from test results, show that fiber strength increases and matrix strength decreases from bottom to top, whereas, fibers modulus decreases and matrix modulus increases from bottom to top of bamboo culms. To increase usability of bamboo like wood, layered laminate bamboo composite (LLBC) is fabricated from laminae using adhesive. The properties of LLBCs obtained were resembled with the properties of the teak wood. Fracture behaviour of laminas and LLBCs under tensile loading conditions were studied using scanning electron microscopy (SEM).
