Utilization of Natural Cellulosic African Teff Straw Fiber for Development of Epoxy Composites: Thermal Characterization with Activation Energy Analysis

Blog Article

This article focuses on the utilization of cellulosic fiber African Teff straw, for the fabrication of epoxy composites.5 and 10% NaOH solution is used for surface treatment of fiber.Compositional and XPS analysis is preformed for untreated and treated fibers and O/C ratio is evaluated.Impact, morphology, crystallinity, thermal characteristics and activation energy of untreated and alkali-treated Epoxy composites reinforced by blu dot wall hook this fiber are studied.Isoconversional FWO and Friedman are applied for understanding the degradation behavior along with apparent madelaine chocolate advent calendars activation energy of composites.

5% alkali-treated composites have improved thermal stability and has apparent activation energy 249 kJ/mol, which is 16% higher compared to untreated composites.Compositional and XPS (X-ray photoelectron spectroscopy) analysis of fiber and characterization of composites along with XRD (X-ray diffraction) analysis also support these findings.Composites reinforced by optimally treated fiber can be utilized for semi structural applications.
