Analysis of the Mechanical Strength of Composites Based on Cigarette Filters and Glass Powder

Cigarette filters and glass are hazardous wastes that directly impact the environment and living creatures. Cigarette and glass filter waste has increased in volume, potentially causing environmental damage by polluting soil and air quality. The research aims to recycle and determine the mechanical strength of making composites from waste cigarette filters and glass. Composites combine two or more components, where cigarette filters are used as fibers and powdered glass as a filler. Waste cigarette filters are processed into fibers and glass is ground into powder with a size of 120 mesh. The matrix uses polyester resin as a composite material binder. They are making composite specimens using a press molding machine. The DoE (Design Of Experiment) method is used in composite fractional factorial design. Tensile and impact testing was carried out twice, with the first impact testing from the pilot study being used as a parameter reference. The results of the composite composition produced eight test specimens. The optimal impact test results are the second specimen, with a value of 0.021 J/mm2, with composition resin polyester 50% and powder glass 50%. The results of the tensile testing of the second specimen, namely 32.17 Mpa. The results of testing the composite of cigarette filter waste and glass had optimal strength in the second specimen in impact and tensile testing. Glass waste influences increasing mechanical strength in making composites.
