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 ...
متن کاملViscoelastic properties of bamboo
Dynamic viscoelastic properties of bamboo were determined in torsion and bending. Damping, measured by tan δ, in dry bamboo was relatively small, about 0.01 in bending and 0.02 to 0.03 in torsion, with little dependence on frequency in the audio range. In wet bamboo, damping was somewhat greater: 0.012 to 0.015 in bending and 0.03 to 0.04 in torsion. The anisotropy in damping implies a purely c...
متن کاملIntroduction of sulfonated bamboo (bamboo-SO3H) as a new catalyst for the facile synthesis of bis(indolyl)methanes
Bamboo is one of the important biopolymers which is used in chemistry. In this work, for the first time, a solid acid catalyst from bamboo was prepared from the reaction of sawdust bamboo and chlorosulfonic acid. Relevant properties of catalyst were investigated by FT-IR, XRD, SEM and TGA. The sulfonated bamboo (bamboo-SO3H) with several acid functional groups was utilized as highly ...
متن کاملDissolving Pulp Production from Bamboo
Commercial bamboo chips were evaluated as raw material for dissolving pulp production. The chips were auto-hydrolyzed (AH) and subsequently cooked by the NaOH/AQ process and bleached to full brightness with the O-CCE-D-(EP)-D-P sequence. The term CCE designates a cold caustic extraction stage. The bamboo chip chemistry (22.4% lignin, 19.5% xylans, 49.3% cellulose, 16.8% total extractives, and 1...
متن کاملFlowering in Bamboo: an Enigma!
The switch to flowering is the most important event in the life cycle of a plant, signaling its commitment to set seed ensuring survival of the species. Effective and efficient pollination leading to seed set requires that all individuals in a population flower together. Environmental cues are the most effective in bringing about simultaneous flowering in populations growing over wide extents o...
