PTFE/PEEK机器人关节轴承材料的力学性能研究
Study on Mechanical Properties of PTFE/PEEK Materials for Robotic Joint Bearings
摘要
Abstract
In order to enhance the mechanical properties of polytetrafluoroethylene(PTFE)/polyetheretherketone(PEEK)materials for robotic joint bearings and to match them with rational forming processes,PTFE/PEEK composite porous materials were prepared based on fused deposition mouldin(FDM)and hot-press sintering processes,respectively.The materials were then subjected to heat treatment modification and mechanical property testing.The results show that under the same component parameters,the porosity of the samples formed by the FDM process is higher.Heat treatment modification can significantly improve the mechanical properties of the samples.Compared with the hot-press sintered samples,the improvement in mechanical properties of the FDM-processed samples after heat treatment modification is more pronounced.After heat treatment modification,the tensile strength of the hot-press sintered samples increased by approximately 11.34%,while the tensile strength of the FDM samples increased by an average of about 18.94%.The impact mechanism and effect of heat treatment modification at different stages on the mechanical properties of the materials vary.For both hot-press sintered and FDM samples,the optimal heating rate is 6℃/min and the optimal holding temperature is 220℃.The holding time has a relatively minor impact on the tensile strength of each sample.关键词
