Mechanical Studies on Polycaprolactone Based Green Composite

In the last decade, there was growing interest in the use of green composites because of their environment-friendly nature, improvement in mechanical & chemical properties, better processability, and low cost. In this work, short sisal fiber was reinforced in a polycaprolactone (PCL) matrix and four different degradable green composites were developed with different weight fractions. Experimental studies were conducted as per standard to find the mechanical properties of PCL based composites. The data obtained shows that there is a 22% increase in tensile strength, 18% increase in hardness and 100% increase in impact strength for the specimen with 10% sisal fiber compared to neat PCL specimen. The mechanical property reduces when the fiber content is increased to 15%. These PCL based composites shall find applications in the packaging industry and consumer goods that have less service temperature.
