Sustainable waste cotton and pigeon pea stalk fibers composite materials for acoustics and thermal properties

This study focuses on the development and characterization of pigeon pea stalk/cotton fibers mixed with a blend ratio 50/50, 70/30, 30/70, 60/40, 100/0 waste cotton 0/100 stalk composites are equipped compression molding system. The entire composite samples tested for acoustics, thermal physical parameters as per American Society Testing Materials standard (ASTM). sound absorption coefficients (SAC) were measured according to ASTME1050 by an impedance tube method, SAC over six frequencies 125, 250, 500, 1000, 2000, 4000 Hz calculated. result revealed that prepared from cotton/pigeon have confirmed more than 80% provided best insulation, absorption, moisture fiber properties. effect exposed materials arranged cotton/pea established further 75% immersion measure 28% handed fashionable Appropriation, immersion, humidity materials. satisfactory resistance at high situations without disturbing insulation
