The utility of composites in today’s modern world is not hidden from anyone. From tiny objects like football to aerospace, everything involves the use of composites. Composites nearly form the backbone of our society. Composites are basically made from matrices and reinforcement. Out of the majority of reinforcement being used, Glass fibers usage cannot be neglected. These are made of fine fibers of glass (made of SiO2). They are used to reinforce various materials like arrows, bows and crossbows, translucent roofing panels, tent poles, boat hulls and paper honeycomb. This review paper is a study of various research papers related to mechanical properties of glass fibers when used with different type of matrices namely, tensile strength, impact strength and flexural strength.
In recent times, the use of discarded single-use plastics in the manufacture of value-added products has increased drastically. Their use as recycled materials significantly reduce the environmental impact of waste plastic pollution, encourage sustainability, and provide an alternate solution to their disposal. This research also investigates and discusses the use of recycled low-density polyethylene in the form of milk pouches, collapsible tubes, and medicinal strips along with coir fiber as reinforcement for the fabrication of polymer composites. Composites were manufactured by compression molding technique and the effect of fiber surface treatment on the mechanical, morphological and structural characteristics was studied. Thermal stability was also studied by differential scanning calorimetry. It was observed that treating cellulosic fibers with 5% NaOH improved the wettability and interfacial adhesion between the fibers and matrix. Thermal stability was increased and a better mechanical property was achieved. Based on the finding of this research, it was concluded that using recycled plastic could produce a notable reduction in waste accumulation and the composites made by their incorporation also show better mechanical and morphological properties. They proved to be a sustainable and greener solution to the problem of waste management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
