This paper presents the study of the tensile properties of Sansevieria trifasciata – fiber (here after called STF) reinforced polyester composites. The composite sample was fabricated with five different fiber lengths of STF (2, 4, 6, 8 and 10 mm). The fabrication was made by hand lay-up technique. Mechanical properties were determined using tensile testing. An interact between fiber and matrix was observed from the SEM (scanning electron microscope) micrographs. The study reveals that the tensile strength increased with fiber length without effecting the elongation at break of the composite.
From an environmental point of view biodegradable polymers offer an interesting alternative to classical plastics. Example of polymers completely made from renewable resources, are polyesters such as polylactide (PLA). Its properties are especially suitable for food packaging. PLA can be used in a wide range of packaging applications for example fruit and vegetable. The novel polymer is forging roles in thermoformed trays and containers as well as shopping bags and labels. It is convenient to processes on conventional extrusion and thermoforming equipment. PLA is compostable under industrial conditionsall of packaging is certified in according to the standard EN13432:2000 by DIN CERTCO and qualify to use IBAW compostability logo. In additioni, increased efficiencies in the manufacturing process and the rising prices of petrol oil have led to the cost of PIA becoming comparable to other conventional plastic materials.
