In recent decade, polymer matrix composites were extensively used in various engineering applications owing to their advanced properties over conventional materials and enhanced performance. This motivated the researchers to generate an extensive study and research work on polymer composites. In recent studies, the erosion properties of the polymer composite attract increasing attention among researchers. The potential enhancement in the erosion resistance property of filled composites tempted the researchers to find the feasibility of using various filler materials in polymer matrix for specific erosion resistance applications. However, only limited numbers of literature are available concerning the tribological performance of the filled composite. Hence in this study, an objective was set to review the various literature that explain the erosion characteristics of filled composites.
The objective of this research is to examine the low velocity impact (LVI) and effect of compression after impact (CAI) properties on flax fiber and basalt powder reinforced polyester composites. For this study the 10 layers of flax fiber, basalt powder by varying from 5% to 30% the composites were prepared. In the LVI analysis composite (10 layers of basalt/10% of basalt powder) shows better results about 1755 N of force and for CAI also same composite B experienced with less deformation and more residual energy to absorbing the force of about 2250 N. The addition of filler material up to certain limit will support the reinforcing fiber to achieve some enhanced property. The morphological changes and their properties were assessed using Fourier Transform Infrared Spectroscopy (FTIR) and x-ray diffraction Analysis (XRD) studies for particulate basalt powder. The presence of Pyroxene group of rocks in basalt powder responsible for stability in high temperatures seen using XRD analysis. The band width around 3390-3425 cm −1 shows the presence of hydroxyl group (OH) in the basalt powder. This proved that the materials are Polar Hydrophilic in nature examined with FTIR spectroscopy.
Natural fibre composites are the promising replacement for synthetic fibre owing to their improved properties, and more importantly, natural fibres are biodegradable and of low cost. These characteristics have made them viable for contemporary engineering and structural applications. However, large scale production of natural fibre composites is in prone because of the challenges in manufacturing and machining. Fibre composite exhibits poor machinability characteristics owing to their heterogeneous and anisotropic behaviour. To overcome this problem, various steps and new methodologies have been established in the view to produce quality machining in natural fibre composites. In recent years, the possibility of conventional machining in natural fibre composites was also discussed. In the present review study, an effort has been taken in studying the fibre composite’s machining characteristics and their failure mechanism in both conventional and unconventional machining. The influence of process parameters in machining different natural fibre composites is also discussed.
