Volume Percentage of Petung Bamboo (Dendrocalamus Asper) Woven Stripas a Reinforcementof Epoxy Resin Composites to the Tensile Strength

Petung bamboo (Dendrocalamus asper) is one material that is easily available, cheap, environmentally friendly, the availability of sufficient natural composite material can be used as a metal replacement. This study aimed to use petung bamboo made in the form of strips as epoxy resin reinforcement in composite materials. By making a petung bamboo woven strip immersion for four weeks in sulfur water obtained from the mountains in the Toraja area with volume strip varying from 20%, 40%, and 60% were then tested the mechanical properties with a tensile strength test. The results showed that with increasing volume percentage petung bamboo woven strips are used, the tensile strength of the composite materials is on the increase and the highest at 60% volume strip petung bamboo woven strips ie 39.139 N/mm2 . It can be concluded that petung bamboo woven strip is an immersion in sulfur water as an epoxy resin booster can increase the strength of the composite material. Where more and more volume strips were added increasing the strength of the composite material. So the petung bamboo woven strip can be used as an alternative composite materials epoxy resin composite material reinforcement.
