Mechanical and abrasive wear behavior of carbon fabric reinforced epoxy composite with and without fly ash cenospheres

Abstract: Carbon fabric reinforced epoxy and carbon fabric reinforced epoxy containing different weight fraction of silane-treated fly ash cenospheres filled composites were cast, sectioned, and subjected to three-body abrasive wear tests for evaluating the abrasive wear behavior. Mechanical characterization was done and a comparison was made between the different samples. Abrasive wear tests were performed on a rubber wheel abrasion tester under different loads, abrading distances using quartz and silica sand as abrasives. The results showed that both unfilled carbon fabric reinforced epoxy and fly ash cenospheres filled carbon fabric reinforced epoxy composites exhibit differing magnitudes of wear volume loss, it being highest for unfilled carbon fabric reinforced epoxy composite. The data trends point to the fact that the wear volume and specific wear rate decreases with increasing fly ash cenospheres loading in carbon fabric reinforced epoxy composites. It was found that silane-treated fly ash cenospheres could...

Privacy of Big Data: A Review

Abstract: Big data has become Buzzword in recent years. It is due to the fact that voluminous amount of structured, semi structured and unstructured data that is generated in the digital era. But, this huge data can be tracked and used for monetary benefits which thwart individual’s privacy. Hence numerous fruitful researches are made in privacy preservation. This book chapter lays emphases on the state-of-art privacy preserving data mining mechanisms and reviews the application of these mechanisms in big data environment.

Eco-friendly Application of Nano Chitosan in Antimicrobial Coatings in the Textile Industry

Abstract: An attempt was made on, chitosan synthesized into nano particles and characterized through Transmission Electron microscope (TEM ) and Dynamic light scattering (DLS). The indiv idual size varied fro m 5 n m to 180 n m respectively in TEM and DLS. Nano ch itosan particles were applied on 100% cotton, viscose and polyester material to impart anti microbial finish. The Fourier Transform Infrared spectroscopy (FTIR) and Scanning Electron Microscope (SEM ) analysis exposed the embedding of ch itosan nano particles. The treated fab rics were tested for anti microbial act ivity as per AATCC 100-2004 and AATCC 124-2009 and the results show that the demonstrated significant antibacterial activ ity against S. aureus in both qualitative and quantitative tests. The physical properties of treated and untreated fabrics are also analyzed and reported. The environmental testing included an effluent treat ment and recycling and selected heavy metal contents and formaldehyde. A biological method using the sequence Lactobacillus acidophilus was proposed to determine the viability of reusing contaminated water d ischarged. Contents of selected heavy metals and formaldehyde have also been tested in Atomic Absorption Spectroscopy (AAS) and UV-Spectrophotometer and reported. Finally these treated fabrics proved that it is durable and eco-friendly p rocess and discharged effluents were also environ mental free and cost effective process.
