Pengaruh fraksi volume serat pandan laut terhadap kekuatan bending dan tarik komposit polyester
Humans have always been trying to create products that consist of a combination of more than one material to produce a stronger material. This is driven by the need for materials that can meet certain desired characteristics. One result is composite material. Composite material with natural fiber reinforcement is one of the composite materials expected in the industrial world. This study aims to determine the effect of the volume fraction of pandanus tectorius fibers on bending and tensile strength composite with polyester resin. This research uses experiment method. The experimental use bending and tensile tests (with variations on four fiber volume fractions of 10%, 15%, 20%, and 25% with three repetitions respectively). While the data analyst used is One ways Anova.In the tensile test the highest value of the tensile strength of pandanus tectorius fiber composites is in the fiber volume fraction of 25% is 25,52 MPa and the lowest value in the fiber volume fraction of 10% is 20,15 MPa. Similarly to tensile testing, in the bending test the highest bending strength value was found in the fiber volume fraction of 25% which was 53.16 MPa and the lowest value was in the fiber volume fraction of 10%, which was 28.86 MPa.
