This research presents on the two different fillers composites filled with aerosil and wollastonite fibers respectively were dispersed on to the Polylactic acid (PLA). Two different systems were prepared such as system-1(i.e. PLA + aerosil) and system-2 (i.e. PLA + wollastonite). In this connection synthesis of polylactic acid solution and development of composites were prepared with aerosil as filler. Tensile strength and modulus were examined with the help of Instron Universal Testing Machine. Using hand layup technique was used to prepare the composite. Glass moulds are used for casting purpose. Tensile strength and tensile modulus and chemical resistance were measured for the above mentioned two different systems. PLA composite film thick was increased from 1-1.5mm for all the composites. Aerosil and wollastonite filler ratios were considered as 0.1, 0.2, 0.25, and 0.3 wt.% respectively for both the systems. Among two systems system-2 got significantly good performance than the system-1. And also weight of the system-1 is lesser than that of the system-2 as aerosil has high specific volume when compared with wollastonite filler.
