Composite Materials
Fabrication of bio-composites material from water hyacinth (Eichhornia crassipes) and polyester resinNatural fiber-reinforced polymer-based composites are proposed as attractive candidates to replace or reduce the use of synthetic fibers because of their many advantages. Water hyacinth fiber (WHF) is a cellulosic material with high absorption and great potential for composite materials used.
The ammonium adsorption capacity of coffee husk‑derived activated carbon composite with MnFe2O4In this study, a composite material between MnFe2O4 and activated carbon from coffee husks (MFO/AC) was synthesized using co-precipitate and hydrothermal methods to remove ammonium from aqueous solutions. The characteristics of MFO/AC were characterized and evaluated by scanning electron microscopy (SEM) and Fourier transform infrared spectra (FTIR).

Evaluate the influence of enamel-shade composite thickness on the overall color of aesthetic dental restorationsComposite materials are widely used in aesthetic dental restorations due to their advantages, including minimal invasive preparation, high mechanical strength, adhesive durability, biocompatibility, time and cost-effectiveness. This study investigates the effect of enamel-shade composite thickness on the final color values of restorations using a two-layer technique to replace enamel and dentine.

Analysis of mechanical properties of jute fiber strengthened epoxy/polyester compositesIn recent years, efforts have been made to produce advanced composite materials in order to lessen environmental impact and to extent sustainability. Traditional materials are largely substituted by composites due to their greater properties like flexural strength, low thermal expansion and high strength.

Master's thesis of Engineering: Evaluation of damage in structures using vibration-based analysesThe aim of the research was the processing of the vibration signatures from healthy and damaged composite beams acquired with the help of a Scanning Laser Vibrometer (SLV) upon excitation and analysis of the mode shapes acquired for damage detection. The displacement mode shapes acquired were then converted into curvature mode shapes with the help of a Central Difference Approximation method (CDA). A major part of this project was to identify the dynamic responses from composites structures for damage detection, the pattern recognition techniques that could potentially be used to interpret the structural responses, and to determine a means of extracting the size and location of the damage from the responses.

Semi-analytical study of thick polymer composites behavior during curing processComposite materials show different mechanical properties in different directions which leads to complications in the prediction of their behavior. In addition to being inhomogeneous, behavior of composite materials is highly dependent on the curing process and many studies have tried to address these issues.
