الوصف: The design requirements in various engineering applications have necessitated the development of novel materials. The Glass Fiber (GF)/vinyl ester composites are one such class of materials finding widespread application owing to their superior mechanical and chemical properties. The addition of fillers has further increased their application spectrum. Although these materials can be produced to a near-net shape, but still drilling of holes is necessary to ascertain the assembly of complex products. With an increase in demand, it becomes imperative to develop high quality cost effective technology for their manufacturing. The present research initiative is an attempt to experimentally investigate the drilling characteristics of GF/vinyl ester composites. The effect of drill geometry, the cutting speed and the feed rate has been found on the drilling forces and the surface roughness of the drilled hole wall. The relative significance of the various parameters has been found using ANOVA. The results of the ...

الوصف: Drilling is one of the most important method for hole making in composite materials. Drilling of polymer matrix composites causes substantial damage around the drilled hole. Damage free holes can be made using modified drill geometry. The present research investigation focuses on the drill geometry as candidate parameter that influence drilling forces and drilling-induced damage. The four different drill geometries (solid and hollow in shape) are used for drilling in composite materials. The cutting mechanism of these drill geometries is substantially different, and therefore influences the drilling-induced damage. The experimental results suggest a strong relationship between the drill point geometry and the drilling-induced damage.

الوصف: The polymer matrix composites (PMCs) are increasingly being used in structural applications owing to their superior mechanical properties. The in-service performance of composite materials requires them to perform under a variety of loading environments. Although a lot of research work has been done towards the mechanical characterization of PMCs, a lot remains to be done in special cases such as characterization of glass fiber reinforced plastics (GFRP) laminates with drilled hole. It is an established fact that drilling in composite laminates causes damage around the drilled hole and the damage influences the mechanical behavior of GFRP laminates under different loading conditions. The present investigation aims at studying the compressive behavior of GFRP laminates with drilled holes. The holes have been drilled at various input parameters (cutting speed, feed rate and drill point geometry) and the effect of these parameters on the compressive behavior of the GFRP laminates has been investigated using statistically designed experiments. It has been found that the drilling parameters significantly affect the compressive behaviour of laminates with drilled holes.

الوصف: The continued expansion of fibre-reinforced plastics (FRPs) into non-specialist markets depends on the creation of high-quality products using cost-effective production techniques. The assembly of complex FRP products requires the drilling of the FRP, however, currently there tends to be substantial damage to the FRP area around the hole. A number of methodologies have been adopted to minimize this drilling-induced damage. There is a strong ambiguity regarding how the operating parameters affect the cutting forces and thus the drilling-induced damage. The present investigation focuses on the geometry of the drill point as a candidate parameter that influences the drilling-induced damage. The experimental results suggest a strong relationship between the geometry of the drill point and the drilling-induced damage.
