Abstract
Bio composite is a combination of a material consisting of more than two ingredients, and combined to form a material that has different properties from the original material. With the abundance of sago fiber in Meranti Regency, this can certainly be utilized especially in the sago peel that is often thrown away and causes waste. So that this skin can be used for making composites, by combining sago tree fiber with polyester resin. To find out the mechanical properties, composite testing of bending strength and impact toughness is needed. With a volume variation of 80% resin + 20% fiber, 70% resin + 30% fiber and 60% resin + 40% fiber. With the hope to get the right composition, and increase the use of sago tree waste, to become a new material. This stage begins with the selection of fibers, and mixing of polyester resins. Specimen preparation and testing procedures refer to ASTM D790 for Bending and ASTM D6110 for Impact. The results of the impact and bending tests show the strength of the largest bending test is 22.39 N / mm2, for a volume fraction of 60% resin + 40% fiber. While the lowest strength for bending test is 8.85 N / mm2, for volume fractions of 80% + 20%. And the greatest impact toughness is 47,173 J for 60% resin + 40% fiber volume fraction, while the lowest impact strength is 37,674 J, for 80% resin + 20% fiber volume fraction. It can be concluded that if the specimen is large in fiber fraction, it will have better strength and toughness of the specimen.
