“…In natural fiber reinforced polymer composites, several factors influence the manner in which composite materials absorb water. These factors include: fiber volume fraction, temperature, fiber nature, difference in water circulation within the composite, degree of crosslinking and crystallinity, diffusivity and the response between water and the polymer [124,125]. Moisture absorption into composite materials is driven by a major mechanism, known as diffusion.…”

Natural fibers, as replacement of engineered fibers, have been one of the most researched topics over the past years. This is due to their inherent properties, such as biodegradability, renewability and their abundant availability when compared to synthetic fibers. Synthetic fibers derived from finite resources (fossil fuels) and are thus, affected mainly by volatility oil prices and their accumulation in the environment and/or landfill sites as main drawbacks their mechanical properties and thermal properties surpass that of natural fibers. A combination of these fibers/fillers, as reinforcement of various polymeric materials, offers new opportunities to produce multifunctional materials and structures for advanced applications. This article intends to cover recent developments from 2013-up to date on hybrid composites, based on natural fibers with other fillers. Hybrid composites preparation and characterization towards their applicability in advanced applications and the current challenges are also presented.

“…The experimental results indicate that the coefficient of friction and wear rates are minimized with the addition of filler content to composites. E-glass/jute fiber reinforced epoxy composites are produced with an addition of Al2O3 and bone powder using hand layup Main effects plot for weight loss technique and a comparison for wear behavior of these composites is made at similar test conditions [134]. The Taguchi's (L27) design is applied for three control variables including sliding velocity, filler content and normal load.…”

Tribology deals with interacting surfaces in sliding, rolling or any others types of motions, which is much importance in designing for machine components to improve their durabilityâ€™s of mechanical engineering systems. This study overviews the most recent studies on the tribological behavior of polymeric based materials containing different fillers. Some microstructural and mechanical properties of the epoxy composite are introduced. In addition, mechanisms of increasing wear resistance and reducing friction coefficient for polymeric composites are reviewed. An overview is also covered the process optimization for the dry wear results of polymeric composites using Taguchi Method (TM) and Response Surface Method (RSM). Furhermore, future use of the fiber reinforced composites in tribological applications is included in this study.

“…The study reveals that addition of cenosphere filler to the bamboo-epoxy composite reduces its erosion wear rate. Deshpande and Rangaswamy [5] developed E-glass/jute fiber reinforced epoxy composites with an addition of Al2O3 and bone powder by using hand-lay-up technique and to compare tribological properties of these composites under similar test conditions. The wear experiments were designed according to Taguchi's (L27) orthogonal array.…”

In this study, ZrN coatings are applied on glass and carbon fiber reinforced epoxy composite materials by magnetron sputtering method to gain an improved understanding of the solid particle erosion (SPE) wear resistance. The tests were carried out by selecting two different impact velocities (34, 53 m/s), four different impingement angles (30°, 45°, 60°, 90°) and two different abrasive (SiO2) particle sizes (approximate 250, 500 m). The thickness of ZrN coating material was 0.15 m. Protective coatings produced by using Physical Vapor Deposition (PVD) method can increase the life time of the components. All test specimens regardless of their various parameter properties exhibit maximum erosion rates at 45 impingement angle and thus exhibiting similar behavior as that observed for semi ductile materials. Optic microscopic views were performed on the surfaces in order to characterize the erosion mechanism. The erodent particles of the both coating layer and composite matrix were found of main role in governing the wear progression. The measured erosion rates were sensitively correlated with the material removal process in order to explain the changes within the coated interfaces. Moreover, an erosion test facility at room temperature and Taguchi's orthogonal arrays were used for experimentation. The expression derived from the results of Taguchi experimental design is proposed as a predictive equation for estimation of erosion rate of these composites. It is demonstrated that the predicted results from this equation are consistent with the experimental observations. Finally, an optimal parameter combination was determined, which led to minimization of erosion rate (ER).
