Carbon Fiber Reinforced

Carbon fiber reinforced plastics (CFRP) has been widely used in airplanes, spaceships and automobiles. The cutting performance of CFRP with a fiber orientation of 0/45°/90°/135° has been studied at different cutting parameters by using PCD tools. Experiences subjected to orthogonal cutting were performed to investigate the effects of cutting parameters on cutting force, surface finish criteria (delamination) and roughness. Results show that CFRP can be milled by high speed and can get good surface quality with low delamination by using PCD tool. The cutting force decreases under the condition of decreasing the cutting width as well as the feed per tooth and raising the cutting velocity. The cutting force is a key point to control delamination that it should below 200N to get comfortable result. As for roughness, when the cutting force below 250N, the more cutting force, the higher surface roughness, and the trend changes when cutting force over 250N. The relation between cutting force and delamination, cutting force and roughness are obtained respectively through multiple regression analysis.

Carbon Fiber Reinforced

The drilling of carbon fiber reinforced plastics (CFRP) is a significant topic for the aircraft industry. However, CFRP are materials which are difficult to cut due to their unique properties. This paper studies tools with excellent cutting performance in machining CFRP. The microcrystalline diamond (MCD), nanocrystalline diamond (NCD), and dual-layer composite MCD/NCD coatings are deposited on Co-cemented tungsten carbide (WC-Co) drills. The morphology of MCD shows pyramidal grains and the NCD and MCD/NCD coatings present cauliflower-like morphology. The cutting performances of coated tools are checked in CFRP drilling tests by the drilling force and tool wear. According to the results, the dual-layer composite MCD/NCD coated tools present the best cutting performance with the lowest drilling force. Meanwhile, the MCD/NCD coated tools display high resistance to wear and adhesive strength.

Carbon Fiber Reinforced

Basing on the milling experiment of carbon fiber reinforced plastics (CFRP), the machining surface qualities of different edge shape and coated tools are researched contrastively. The results show that: when the CFRP is milled by general right-hand edge milling cutter, due to the small tool rake angle, bad tool sharpness, and carbon fibers of upper and lower surface are both subjected to upswept cutting force, the burrs appear at the upper surface of workpiece. But there is no burr at the lower surface. When the CFRP is milled by interlaced edge or herringbone edge diamond coated milling cutter, which are designed to left-hand and right-hand interlace, the carbon fiber of workpiece’s upper and lower surface are subjected to downward and upswept cutting force respectively. There is no burr at the upper and lower surface of workpiece. Compared with interlaced edge diamond coated milling cutter, herringbone edge diamond coated milling cutter is more suitable for finish machining of CFRP.

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.
