Tensile strength polymer matrix composite with reinforcement gigantochloa apus

Abstract

Composite is a combination of two or more materials, where one type materials is mixed into another type of materials. Combining several different phases will create a material with performance better than the earlier phase of the constituent. In this study, a composite consisting of a polymer matrix by using a type of epoxy thermosets, reinforced using natural bamboo.The bamboo species used in these tests were GigantoacloaApus, age 3 – 4 years, collected from Bogor Indonesia. The bamboo were cut into lumber strip fiber parts using a cleaver and hand saw. The strip were cut by knife to thikcnesses of 0,5 mm – 1 mm and witdh 1,5 mm – 2 mm. The next process is to soak bamboo with 5% NaOH for 72 hours and dried at room temperature of27o C -29o C for 48 hours. The types of bamboo weave are plain weave, twill weave,basket, and 4 harness Satin, with laminate size 400 mm x 400 mm.x 1 mm. The manufacture process was by hand lay-up end cut with a laser, according to ASTMD 3039-08 standards. The orientation angles are of 0o, 45o, 90o, where each sample taken three specimens,furthermore, the tension test process.The result orientation angle 0o, the highest tensile strength at 4 harness satin woven type: 52.9833 N/mm2. Orientation angle of 45o to the highest value of tensile strength on the type of woven basket: 17.7230 N/mm2 at an angle of 90o orientation of the highest tensile strength values on the type of woven twill: 39, .5813 N/mm2. The orientation angle 0o, the highest strain at basket woven type: 3.2657%. Orientation angle of 45o to the highest value of strain on the type of woven basket: 11.3099% and at an angle of 90o orientation of the highest strain values on the type of woven basket: 3,.4976 %.
