Composites are widely used in all the fields because of its favorable properties over conventional materials. Medium Density Fiberboard (MDF) is an extensively used wood composite in furniture industries. Drilling is the most commonly used machining process in the assembly. The surface quality of the hole depends upon the cutting conditions. The drilling damages like delamination reduces the structural reliability of the laminates and also affects the assembly of parts, appearance and the performance of the final product. The objective of this study is to analyze the influence of cutting parameters in a systematic approach on delamination in drilling of prelaminated MDF wood panels with High Speed Steel (HSS) twist drills of different diameters. The drilling experiments were planned and performed using Taguchi design. Response Surface Methodology (RSM) based mathematical model is developed to predict the influence of process parameters. The adequacy of the model is checked using Analysis of Variance (ANOVA). The results showed that the most dominant factor which influences the delamination is feed rate followed by the drill diameter.Keywords

The composites are gaining significant position among various materials nowadays due to their unique features and properties. This Technological development in the materials sector has created interest among engineers and scientists to create new materials with different features and required properties. Among the various new developed materials, Carbon Fibre Reinforced Carbon (CFRC) composite material is occupying important place. This composite material is used mostly in the manufacturing of advanced structures like rockets, space shuttles, missiles, aircrafts etc. Generally these composites are very costly in nature and the addition of drilling cost of these materials makes them more costly. Hence the machining parameters are carefully selected, so that no drilling damage is caused during machining. The main objective of this paper is to find the optimal drilling parameters by using Taguchi method and the unique Grey Relational Analysis technique. The drilling experiments were carried out on a RCC composite plate with High speed steel tool on the VMC100 computer numerically controlled drilling machine, at the workshop of Anna university campus, Chennai, India.

Dry sliding metal-metal wear behavior of Al6061 alloy, discontinuously reinforced with fine particles of SiC and Al2O3 are presented and discussed this paper. The discontinuously reinforced aluminum (DRA) alloy composites with 5-25% volume fractions of SiC and Al2O3 particulates were produced by stir casting method and using them test specimens were prepared. The dry sliding behavior of these hybrid composite specimens and that of Al6061 unreinforced alloy at room temperature was investigated by using pin-on-disk wear testing machine over a load range of 29.43N-49.05N (3-5 kgf) for a total sliding distance of 1413m at a constant sliding speed of 1.57m/s. The results show that, the reinforcement of the metal matrix with SiC and Al2O3 particulates upto a volume fraction of 25% reduces the wear rate at room temperature. Higher the volume fraction of the reinforcements lower was the rate of wear. The results also show that the wear of test specimens increase with increasing load and sliding distance. Also micro hardness of the specimens at the room temperature was measured before and after the wear tests by Vickers hardness testing machine. The micro hardness of the hybrid composite test specimens increases with increasing volume fraction of particulates reinforcement. The optical micrographs taken for the micro structure analysis of the hybrid composite specimens show that the SiC and Al2O3 particulates are uniformly distributed in the matrix. It was also found from the optical micrographs that the porosity of the test specimens increases with the increasing volume fraction of particulate reinforcement. The wear surfaces were examined by scanning electron microscopy, which showed that the wear surface of the composite alloy was generally much rougher than that of the unreinforced alloy. Large grooved regions and cavities with ceramic particles were found on the worn surface of the composite alloy. This indicates an abrasive wear mechanism which is essentially a result of hard ceramic particles exposed on the worn surface.Keywords

Objectives: To study the effect of modified (OMMT) nanoclay polyester resin on dynamic properties of Glass Fiber Reinforced (GFR)- Polystyrene Foam (PS) sandwich laminates experimentally. Methods/Analysis: The GFR– PS foam sandwich laminates are fabricated by hand lay-up process. Free vibration test has been conducted to evaluate dynamic properties of glass laminate and sandwich laminates. The morphological picture of the nanoclay dispersion in the polymer fracture samples has been investigated by using Scanning Electron Microscopy (SEM). Findings: The dynamic properties of the nano polyester sandwich have been significantly improved at 4% of nanoclay loading. Application/Improvement: From the results it is observed that, the effect of nano particle in fabricated composite significantly increases the dynamic properties.Keywords
