Flexural properties of bamboo strip composites on lamina configuration. Issue 1 (July 2020) - Djamil, Sofyan
Abstract: Composite of laminate is a type of composite consisting of two or more layers combined into one and each layer has special characteristics. This research is expected to increase the use value of bamboo so that in the future large industries can utilize bamboo as much as possible, given the advantages possessed by these natural materials. The aim of this research is to find out the effect of the angle configuration on the flexural properties of the three-layer laminate bamboo composite. The type of matrix material and reinforcement used in this research are epoxy polymer resin and Apus bamboo woven with plain woven type. The bamboo composite angle configuration consists of 0 0, 45 0, 90 0 with laminate variation 0 0 /0 0 /0 0 ; 0 0 /45 0 /0 0 ; 0 0 /90 0 /0 0 . Flexural testing with specimen size follows ASTM D7264/D7264M.07 standards. From the results of the tests, it can be concluded as follows: Flexural strength for orientation angle 0 0 /0 0 /0 0, value 47.31 ± 1.21 MPa, orientation angle 0 0 /45 0 /0 0, value 38.20 ± 1.33 MPa, orientation angle 0 0 /90 0 /0 0 value 41.03 ± 2.12 MPa.
