A Study on Biodegradable Composite Prepared from Jute Felt and Polyesteramide (BAK)

Abstract

Jute-polyesteramide(BAK) composite specimens having 45, 50, 55, 60 and 65% of jute by mass were prepared following film stacking method by compression molding technique. It was found that with increase in jute content, the flexural strength and modulus increased from 25.89 and 4709 MPa (45% jute) to 41.75 and 8613 MPa (60% jute) respectively and thereafter decreased with higher loading of fiber. For tensile strength and modulus, the same trend was observed. At 45% jute content, the values were 33.61 and 2599 MPa respectively, whereas at 60% jute content the values were 41.23 and 3346 MPa respectively. The thermogravimetric analysis of jute felt, BAK film and jute-BAK composites (60% jute) were made. The biodegradability of the composite specimens were studied by soil burial test, IR and SEM analyses.
