Mechanical characterization of chemically treated biodegraded flax/PLA composites

Abstract

Because of its composition, bio composites are completely biodegradable in nature. They can be easily decomposed with little CO2 and water molecule emissions during disposal. The effect of a 12-week soil buried test on the characteristics and degradation rate of treated and untreated flax fibre reinforced composites was investigated in this study. For eco-friendly treatment of flax fibre, sodium bicarbonate with a chemical content of 10% was utilised at different treatment times (24, 48, 72, and 96 hours). The influence of agriculture soil on the degradation rate and mechanical characteristics of produced composites was examined in a soil buried test. The results demonstrate that the pH level of the soil did not change significantly during the test. At and after the 8-week biodegradation period, a quicker rate of degradation was found. Mechanical characteristics of soil buried samples were reduced after two weeks. After an 8- week deterioration period, the tensile and flexural characteristics of produced composites are about 50% of their initial value.
