Edge Trimming

Carbon fiber reinforced plastics (CFRP) are used as structural materials in automotive and aerospace industries because of its superior properties like high strength to weight ratio and high stiffness to weight ratio. Though most CFRP products are produced to near net shape by different composite manufacturing methods, some post machining processes such as drilling, edge trimming are required. In order to shape and smooth the edges of the composite components the edge trimming plays a major role. This research gave the approach of studying the effect of temperature and tool wear on surface roughness obtained during edge trimming of uni directional CFRP with different fiber orientations and quasi isotropic CFRP with the sequence of [90/-45/0/45/90/-45/0/45]S.The effect of coating of tool on tool wear and surface roughness were also studied.

The Impact

In this paper, the impact of milling process parameters on the roughness of surface of glass and carbon fiber reinforced plastics was analyzed. The influence of feed per tooth, cutting speed and depth of cut on selected surface roughness parameters was determined. It was found that the surface roughness after milling carbon fiber reinforced plastics was greater compared to the surface of glass fiber reinforced plastics.

Rotary Ultrasonic Drilling

Carbon fiber reinforced plastics are used in various industrial applications for their excellent properties. Rotary ultrasonic drilling is the new machining process used to drill holes on fiber-reinforced plastics and has been attracting increased attention in recent years. Dimensional tolerances are very important in machining of carbon fiber reinforced plastics. Additionally, diamond core drills are simultaneously drilling and grinding fiber reinforced plastics. This paper aims to investigate thrust force and dimensional tolerances including roundness and cylindricity in rotary ultrasonic drilling of carbon fiber reinforced plastics using diamond core drill. To this end, a proper ultrasonic system for a core drill in ABAQUS is designed and fabricated. Thrust force in rotary ultrasonic drilling when compared to conventional drilling reduced by up to 30%. Besides, roundness and cylindricity decreased by up to 80% and 72%, respectively. Afterwards, analysis of variance demonstrated that vibration is more influential than other machining parameters in order to improve the hole accuracy. That is, obtained exponential regression models predict roundness and cylindricity through machining parameters with high accuracy. Feed rate of 30 mm/min and spindle speed of 1400 r/min by exerting vibration on the tool is considered to be the optimized condition.

The Difference

The paper is concerned with increasing sensitivity of eddy current nondestructive testing of most dangerous delamination in carbon-fiber reinforced plastics (CFRP). Increased sensitivity is achieved by separate registration and comparison of eddy current signals obtained from a set of stratifications of carbon fibers with the same orientation. The separation of eddy current signals is possible due to pronounced anisotropy of the electrical conductivity of the layers dominant in the direction of the fibers of the corresponding layer. Eddy-current signals are registered by eddy current probes with maximum sensitivity in a given angular direction. Prior to the scan eddy current signals of the probe are leveled on a defect-free area. The influence of the working gap on the difference between the eddy current signals of the probe is suppressed by normalizing it according to one of the signals. The analysis of the registered signals from delamination has been performed using an approximate calculation model. The reliability of the obtained results has been confirmed by comparison with experimental results and calculations using the finite element method.
