Abstract Glass fabric/polymer composites are widely used in various industrial applications due to their lightweight, exceptional strength, and fatigue resistance. Graphene nanoplatelets, a recently developed type of carbon material, stand out as unique nanofillers due to their 2D quantum confinement and expansive surface area within a polymer matrix. These features make them more effective than traditional carbon nanofillers at enhancing a range of properties. In this study, 3-weight % of graphene nanoplatelets with epoxy resin were used for investigation by varying sonication durations (0, 20, 40, and 60 min) using an ultrasonic bath sonicator. The laminates More >

Abstract The research paper focuses on manufacturing composite materials from waste polyethylene terephthalate (PET) reinforced with soda-lime glass to provide a lightweight, less brittle, and high rust resistance when exposed to hazardous environment. In developing nations such as Nigeria, there is a significant surge in the volume of bottled water and other packaging materials used in households, leading to a rapid accumulation of biodegradable waste, that presents concerns such as the creation of landfills and health issues. PET are thermoplastic polymer that can be melted and shaped into various objects. This study involves the incorporation of… More >

Abstract In this study, the Polyamide-12 (PA-12) powdered material in the Selective Laser Sintering (SLS) process has been incorporated as the filler in the composite material to enhance its properties. The PA-12 powder has been made into a form of filament and is primarily used in the Fused Deposition Modelling (FDM) process. The PA-12 has been used with epoxy resin and glass fiber with different proportions. The characterization of materials, including the validation of the presence of PA-12 filler with epoxy, has been evidenced using Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), and Thermogravimetric More >

Abstract The use of polypropylene composites in various industrial fields has expanded considerably in recent years. A number of researches have been carried out to characterize the performance of polypropylene and its composites. However, the effects of ageing on the long-term behaviour of this thermoplastic are not well understood. The purpose of this study is to analyse the consequences of thermal degradation on the thermal and mechanical properties of three distinct materials: virgin Polypropylene (PP), virgin Polypropylene + talc (PP/talc), and virgin Polypropylene + Carbon Black (PP/CB) micro-composites. Specimens of these materials underwent exposure in an… More >

Abstract The Cavendish banana, Musa acuminata, is a climacteric fruit that ripens quickly after harvest. Due to their high perishability and susceptibility to disease, bananas have substantial postharvest losses. After harvesting, it is important to extend the bananas’ shelf life. Unique coating gel solutions based on glycerol and ascorbic acid were developed to accomplish this. Chitosan mixed with glacial acetic acid, lactic acid, and sodium alginate were among the gel solutions in these combinations. The goal was to improve banana preservation while maintaining freshness and quality by implementing innovative formulations and techniques. The fruits are hand-dried and… More >

Abstract A chitosan and guar protein isolate blend conjugate (Ch/GPI-Glu) based membrane has been designed and studied for its possible interaction with this biopolymer mixture. The designed conjugate chitosan/guar protein isolate blended membrane was investigated for its structural features using Fourier Transform Infrared Spectroscopy (FTIR), Thermal Gravimetric Analysis (TGA), X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) analyses. IR Spectroscopic data suggested that chitosan and guar protein isolate contributed to a specific intermolecular interaction. The designed membrane was water-insoluble and it exhibited strong polymer–protein interaction. Further, the membrane was also found to have a smooth morphology More >

Abstract In this paper, knitted aramid fiber (AF) was used as the support, and graphene oxide (GO) was loaded on the support by the polydopamine (PDA) method. Epoxy resin (EP) was poured to obtain composite materials. The tribological and mechanical properties of the composites were tested, and the wear surface of the composites was characterized by scanning electron microscopy (SEM) and three-dimensional morphology. The results show that knitted AF can markedly improve the mechanical properties of the composites. As a two-dimensional material, GO plays an effective lubrication role, and GO effectively enhances the tribological properties of… More >
