Experimental investigation of alkaline treatment processes (NaOH, KOH and ash) on tensile strength of the bamboo fiber bundle

The aim of this experimental research is to investigate the effect different alkali solutions, their concentration, and soaking time on tensile strength bamboo fiber bundles. results will suggest method extract in order develop biodegradable composite materials future. Bamboo strips were mechanically separated from Rough Giant Bamboos, they soaked three solutions based NaOH, KOH, ash with individual concentrations (5%, 10%, 20% w/w) for eleven times. then washed naturally air-dried before separating fibers bundles (cross-section area between 0.06-0.27mm 2) by hand pull off. strengths determined according ASTM D3039 standard whereas paper grips technique was applied prevent damage machine clamps. that optimal 48 hours all solution concentration. Moreover, NaOH more than 5% (10%, 20%) destroyed. On other hand, solution, concentration provides same value as one distilled water. Additionally, have proven be able protect fungus growth contrast
