“…The most commonly used fibers for structural applications are glass fibers, Kevlar, aramid, and carbon fibers [5,6]. Since its introduction in 1953, PET (polyethylene terephthalate) fiber has progressively found new and interesting applications in plastics, rubbers, and textile industries.…”

Plastics used in the packaging industry, especially in the form of carry bags and pouches, manifest a formidable threat to the environment because of their non-biodegradable nature. Addition of both natural and synthetic fibers to these materials improves their performance, replacing the conventional materials like wood, metal, and ceramics in the majority of industrial applications. Short polyethylene terephthalate (PET) fiber-reinforced composites from waste high density polyethylene (WPE) such as carry bags/pouches collected from municipal solid waste and neat high density polyethylene (HDPE) were prepared in a Brabender Plasticorder using melt-mixing technique under optimum processing conditions. Physico-mechanical properties of these short PET fiber-reinforced WPE and neat HDPE composites were determined using standard procedures. It is observed that the mechanical strength is enhanced by increasing the fiber-loading up to 50% by weight. Maleic anhydride (MAH) grafting was done onto the WPE matrix and the resulting composites were evaluated for their mechanical properties. The thermal stability of the WPE-PET fiber composites also improves significantly with fiber-loading as well as upon grafting the WPE with MAH. Flexural strength exhibited an increase of 59% from 25.4 to 40.5 MPa, proving MAH-grafted WPE (MAH-g-WPE) to have good compatibilizing ability.

A commercial grade of polypropylene (PP) is reinforced with nylon-6 fibers of three diameters at levels up to 30wt% PP. The addition of the fibers improve the mechanical properties such as tensile strength and flexural strength. The least diameter fibers give the maximum improvement in mechanical properties. Attempts are made to improve the interfacial adhesion between the fibers and the matrix by grafting the matrix with maleic anhydride in presence of styrene. The mechanical properties show significant improvements as a result of these modifications. The recyclability of these composites are also studied, the PP/ nylon composites/blends obtained by recycling the composites also have better tensile properties.

A commercial grade of high-density polyethylene (HDPE) reinforced with nylon 6 fibres of three diameters at levels up to 30 wt% HDPE. The addition of the fibres resulted in improvements in mechanical properties such as tensile strength and flexural strength. Fibres having the least diameter gave the maximum improvement in mechanical properties. Attempts were made to improve the interfacial adhesion between the fibres and the matrix by grafting the matrix with maleic anhydride and also with styrene maleic anhydride. The mechanical properties showed significant improvements as a result of these modifications. The HDPE/nylon composites/blends obtained by recycling the composites also show good mechanical properties.
