The Investigation of KH560 Coupling Agent with Carbon Fiber One Step Dipping Method Compared with Functionalized Multi Walled Carbon Nanotubes
No full textInterlaminar and interfacial properties of composites are important parameters for any application, extensive research has been out bursting to enhance the above properties using nanotubes (NTs) as an alternate solution to minimize delamination of laminates. This research focused on significance of functionalized engineering materials for better efficiency in industries, especially stealth technology. Silane-coupling agent “3-glycidyletheroxypropyl-tri methoxy silane, KH-560” is one module among five modules designed in this work. Five modules are considered as (M1, M2, M3, M4 & M5) with (0.5wt% of AMINE, CARBOXYL, multi wall carbon nano tubes (MWCNTs), 5% KH-560 treated carbon laminate and finally with base carbon fiber). PAN-based 12k carbon fiber as base fiber with functionalized and non-functionalized nanocomposite are incorporated as fillers in the epoxy laminates fabricated using vacuum bagging technique. Findings indicated 5% KH-560 silane treated carbon fiber (module M5) showed best results such as properties with 39%,55% and 20% in “tensile, flexural and interlaminar shear strength (ILSS)” respectively. FESEM analysis is conducted to understand morphology of the laminates
Effects of Geographical Conditions on the Physiochemical Properties of Natural Fiber Extracted from the Root of Prosopis juliflora
Get PDFBiomass-derived Natural Fiber Composites (BDNFCs) are becoming popular in versatile applications in aerospace, biomedical, energy storage automotive, etc. due to their biodegradability, environmental friendliness, and cost-effectiveness. In the current work, root fibers extracted from Prosopis juliflora were selected as the natural fiber. Characterization results for physical and chemical properties on the effects of soil types and moistures in 2 different states of India, i.e. Telangana, and Tamil Nadu on fiber compositions and properties. The results reveals that hemicellulose content of tamilnadu fiber (81 wt%) is less than that of the Telangana fiber (85.7 wt%). Based on analysis results of Fourier Transform Infrared Spectroscopy (FTIR) andThermo Gravimetric Analysis (TGA), Tamil Nadu fiber has the themal stability at 239 °C and maximum degradation temperature at 359.1 °C. Whereas Telangana fiber has thermal stability at 253 °C, and maximum degradation temprature at 387.5 °C. The crystallinity indexes of Tamil Nadu and Telangana fibers were calculated, based on analysis of X-Ray Diffraction (XRD), to be 69.6% and 67.4%, respectively. The crystal sizes of Tamil Nadu and Telangana fibers were 14.38 and 13.21 nm, respectively
