Abstract


Suburban communities around Cilegon usually depend on urban mass transportation. The vehicle has very high mobility when peak hours. Infrequently, this consequent collision and friction between them in the crowd of traffic jams. It causes damage or crushing of their bumper. Hence, a material that has suitable qualifications is needed. One of the materials which have the potential strength to be applied as a bumper car is ramie fiber. As a fiber, this material has high tensile strength properties. In this research, we need to ensure that woven ramie-epoxy composite has a tensile strength value above the standard for car bumper material. The composite consists of woven ramie as the matrix and epoxy resin as the filler at a weight ratio of 40:60. Application curing treatment to the composite with 0-30-60-90-minute. The tensile test results are 30.6 MPa, 36,4 MPa, 36,5 MPa, and 40,8 MPa - the highest values at 90-minute CT. All tensile strength value of the composite is above the standard value required. It also found that the composite water absorption was below the limit of the standard. Based on those values, the woven ramie-epoxy composite can be considered a potent material for use as a bumper car.
