The silk fibres obtained were characterized using various parameters, such as FT-IR, DSC, TGA, colorimetry, tensile strength, XRD, Yellowness Index, CHNS and FE-SEM. The FE-SEM images depicted that the surface of the CDSF (Cocoonase degummed silk fibre), PDSF (Papain degummed silk fibre) and TDSF (Trypsin degummed silk fibre) was comparatively smooth to that of the HDSF (H<sub>2</sub>O<sub>2</sub> + Neutral soap degummed silk fibre) and SDSF (Na<sub>2</sub>CO<sub>3</sub> + NaHCO<sub>3</sub> degummed silk fibre). The absorption pattern in FT-IR indicated slight shifting or vibration of the functional group in SDSF silk fibre. Moreover, much variation was not observed in the mechanical properties of silk fibres. Minor variation in 2θ position can be observed from the XRD plot in case of HDSF and SDSF silk fibres. The DSC graph showed remarkable differences in the thermal properties of SDSF silk fibre comparatively to that of the HDSF and other silk fibres. The TGA study infers that PDSF and CDSF silk fibre were more stable to the degradation. Thus, the present study observes that cocoonase was found to be efficient in degumming tasar cocoons.

The novelty of the work lies in understanding the effect of elastomer placed at different interfaces on damage severity and energy absorption capacity of the laminates. The contact force between the impactor and the laminate was obtained as a function of time, from which displacement, velocity and energy absorption were calculated. Visual inspection was conducted to quantify the external nature of the damage, while the combined internal and external profiles of damage were quantified using through-transmission ultrasonic scanning. Results indicate that the presence of the elastomer layer enhances lateral deflection in the vicinity of the impactor, reducing localised transverse deflection.

This research examines the effect of alumina concentration variations, ranging from 0 to 5%, on the mechanical and thermal properties of FMLs comprising AA6061 aluminum layers, banana fibers, and epoxy resin. The tests revealed that the sample containing 3% alumina in ABFA3 (Alumina-Banana Fiber Laminate) demonstrated the most significant tensile strength (148.6 MPa) and the highest flexural strength (253.6 MPa). It ensured enhanced load transfer capabilities alongside stronger fiber–matrix bonding. The outcome of the impact test showed that ABFA5 secured peak performance by absorbing 4.5 J of energy, resulting in improved impact tolerance. The addition of alumina in FMLs resulted in enhanced thermal stability, where ABFA5 reached its peak degradation temperature of 400 °C, the highest among all samples. The water absorption test revealed that alumina addition lowered moisture intake through ABFA5, which exhibited the best water absorption rate at 7.8%. The quasi-static indentation assessment revealed that ABFA5 achieved a maximum indentation force of 3783.65 N, demonstrating the highest energy absorption level and verifying its exceptional structural capability.

Among all composites, the CaCO₃-filled PP exhibited a distinct selective permeability profile: an oxygen transmission rate (OTR) exceeding the measurable detection limit and a water vapor transmission rate (WVTR) comparable to neat PP. This distinct asymmetry is due to the structural heterogeneity caused by the filler at the highest content, which promotes oxygen diffusion while effectively blocking water permeation.
