The crucial role of face masks is highlighted in our day‐to‐day life during the COVID‐19 pandemic. Polypropylene (PP)‐based disposable face masks are widely used to hold back viral transmission. The discarded masks can create a huge burden of contamination on the environment. The purpose of this work is to recycle and reuse discarded masks to reduce environmental pollution. A simple and innovative technique to recycle surgical masks into composites of higher mechanical strength and antimicrobial properties is explored to reuse in packaging materials and cutleries. The surgical masks composed of PP fibers are recycled to use as a matrix material to reinforce with sisal and hemp fibers. The hot compression molding technique is used to sandwich the PP masks with natural fibers. The tensile strength of the composites is remarkably increased by 197% and 305% for sisal fiber composites and hemp fiber composites, respectively. The tensile elongation also increased to 574% for sisal fiber composites. The resulting composites exhibit notable antimicrobial properties against Staphylococcus aureus , a pathogen responsible for common staphylococcal food poisoning. The composites are found to be suitable to use as food contact cutleries and packaging materials.

“…The properties of natural fiber-reinforced composites (NFRCs) depend on the orientation, shape, length, and diameter of the fibers. [22,23] The natural fibers can be used in different forms like particles, and both as short and long-form fibers. [24] The hybridized composite properties depend on various factors like individual fibers properties, the nature of matrix material, and the compatible nature between matrix and fibers.…”

Environment protection is the current theme for many industries by utilizing biodegradable natural fibers for products development. The growing awareness of the environmental harm caused by synthetic materials has resulted in the emergence of eco-friendly materials. This work aims to fabrication of jute, bamboo, and coir fiber reinforced hybrid composites (12 combinations) with the analysis of mechanical, thermal, and morphological properties. The tensile and flexural tests reveal that the composite JC8 (21% jute, 1.5% coir, 7.5% bamboo) exhibited maximum tensile and flexural strengths of 129.3 and 98 MPa respectively due to higher cellulose constituents in jute and bamboo fibers that resulted in higher degree cellulose polymerization with the epoxy matrix, and also the capability of tension and bending resistance. The combined effect of hybrid fibers stiffness and strong interfacial adhesion were also the reason for maximum flexural strength. The thermal stability of all the composites was remains the same, and considerable weight loss was observed between the ranges of 200 and 500 C. Overall, the hybrid composite JC8 has 21% jute, 1.5% coir, and 7.5% bamboo on the basis of volume percentage exhibited a maximum tensile strength, flexural strength, thermal stability and better surface morphology than other hybrid composites.

“…[22][23][24] Nowadays these fibers are being reinforced with polymer matrices to elevate their potentiality for engineering applications. [25][26][27][28] Even with the elevated properties, the natural fiber-reinforced composites (NFRCs) exhibit some significant drawbacks like high moisture absorption, incompatibility with hydrophobic matrices, and poor wettability. [29,30] With the use of the hybridization technique, it is possible to get improved blended properties when reinforced with two or more different reinforcements.…”

In this current research study, nine different combinations of coir, jute, and bamboo reinforced epoxy composites were fabricated using casting technique. These composites were employed to mechanical tests such as flexural and impact tests, and analyzed the thermal stability through Thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC). Moreover, the thermal conductivity and surface morphology was also studied for hybrid composites. The hybridization of more than one fiber with epoxy matrix resulted in better mechanical and thermal properties as compared to individual reinforcements, and this statement is agreed with the present research work as well as the research works reported in the literature. The hybrid composite with the maximum amount of jute fibers reinforcement with bamboo fiber (B2C0J8) exhibited maximum flexural and impact strengths of 92.521 MPa and 82.4 kJ/m 2 respectively, which is due to the higher modulus and energy-absorbing behavior of jute fibers, also it was an advantage of coir fibers absence having lower modulus and strength values. In thermal conductivity analysis, the marginal variations of values were observed with different volume fractions of fibers, and the maximum conductivity (0.317 W/m-K) was obtained for B2C8J Composite having only coir and bamboo fiber reinforcements with epoxy matrix. The Thermogravimetric analysis results reveal that all nine types of hybrid composites possess nearly equal thermal stability, and slight variations in degradation temperatures were observed in the thermographs. The B2C1J7 hybrid composite was recommended for better mechanical and thermal properties, where it has 89.06 MPa of flexural strength, 78.6 kJ/m 2 of impact strength, 0.233 W/m-K of thermal conductivity and exhibited better surface morphology.
