Daftar Isi:
- Styrofoam waste can lead to environmental problems because it cannot be decomposed naturally. Styrofoam is a thermoplastic, therefore it could be reformed by heating in recycle processes. Styrofoam waste can also be reformed into composites by adding natural fibers such as sensevieria fibers. Objectives of the research are to study the effects of variation in sansevieria fibers loading and the addition compatibilizer maleic anhydride to the mechanical properties of styrofoam- sansevieria composite. The composites were prepared by mixing styrofoam waste, sansevieria fiber with various percentages, and maleic anhydride compatibilizer. The fiber loading is varied between 40 % up to 60 %. The fiber was first soaked in 1 % NaOH solution for 2 hours, washed and then dried prior to composite preparation. Two type of composites were perpared, i.e. the ones without the compatibilizer and the ones with the addition 5 % (weight of maleic anhydride compatibilizer/weight of resin and fiber) of maleic anhydride compatibilizer. Composites were made by using hot press machine at a temperature of 130 oC and pressure of 40 MPa for 10 minutes. Composite materials were tested for their mechanical properties (tensile strength, bending strength, and impact strength) in according to ASTM standards. The results showed the addition of maleic anhydride compatibilizer improved mechanical properties of the composites as compared to those without compatibilizer agent. The addition of fiber up to 60 % loading also improved composite mechanical properties both with and without compatibilizer. The highest values in tensile strength and impact strength were found in the composite with 60 % wt of fiber, namely 1.565 MPa and 5.51 kJ/m2 respectively. The highest bending strength were found in the composite with 40% wt of fiber, namely 4.61 MPa. On the conclusion, the addition of both compatibilizer and fiber increased the mechanical properties (tensile strength, bending strength, impact strength) for styrofoam-sansevieria composites.
