Study About Mechanical Property and Machinability of Carbon-Fiber Reinforced Polyetheretherketone

Short carbon-fiber-reinforced composites, especially short carbon-fiber-reinforced polyetheretherketone composites (CF-PEEK), are used extensively in the engineering field because of their superior properties. However, their surface quality and material removal rate need to be optimized to satisfy design and processing requirements. This work focused on a multi-objective optimization to minimize the surface roughness and maximize the material removal rate during machining by grey relational analysis with an analysis-of-variance (ANOVA) and response surface methodology before a multi-objective mathematical model was established. The statistical significance of the predicted model was examined by using an ANOVA to obtain the optimal machining parameters (spindle speed, feed rate, cut depth). The optimal combination of cutting parameters was a spindle speed of 2600 rpm, a feed rate of 720 mm/min, and a cut depth of 1.8 mm.

“…PCD tool displays an excellent performance when cutting carbon/epoxy or carbon/PEEK materials. 23 PCD tool tends to provide lower roughness than cemented carbide tool when it was used to cut PEEK composites. 5 Photographs of the milling experimental device and the end mill that were used are presented in Figures 3 and 4, respectively.…”

Functional gradient biomaterials have been widely applied in the biomedical field due to their designable structure and performance. In this paper, hydroxyapatite-titanium particles hierarchical filled polyetheretherketone functional gradient biocomposites [(HA-Ti)/PEEK FGBm] were successfully fabricated through combination of a layer-by-layer casting method and hot pressing technology. The microstructure and morphology of the FGBm were investigated by X-ray diffraction (XRD), Fourier transform infrared (FTIR), energy dispersive X-ray analysis spectrometry (EDS) and scanning electron microscopy (SEM). The results of XRD and EDS verified that the components of the FGBm consist of HA, Ti and PEEK. FTIR and SEM studies showed that the existence of TiO2 thin film on the surface of Ti particles was beneficial to improve the wettability of Ti particles to the PEEK matrix, thus increasing the interfacial bonding strength between Ti particles and PEEK matrix. The SEM observation revealed that the size of HA particles in (HA-Ti)/PEEK FGBm was on the nano-scale and that of Ti particles was on the micron-scale. Furthermore, several typical microstructures such as micro-pores, dimple-like, and encapsulated-like morphologies in (HA-Ti)/PEEK FGBm were observed by SEM. With the rise of Ti and HA particle content in PEEK matrix, the distribution of them in PEEK matrix becomes more and more inhomogeneous and they tend to agglomerate.
