Abstract

X-ray diffraction (XRD) analysis of composite samples based on ultra-high-molecular-weight polyethylene (UHMWPE) and polytetrafluoroethylene (PTFE), with a quasicrystalline filler Al–Cu–Fe, has been carried out. Samples with different filler concentrations were subjected to friction. A change in the degree of crystallinity of the polymer matrix is determined on the basis of the XRD data. Comparison of the diffraction patterns recorded at symmetric scan mode and in the grazing-incidence geometry showed a difference in the structures of the surface layers and sample bulk.

摩擦对基于超高分子量聚乙烯和聚四氟乙烯的准结晶填料Al–Cu–Fe复合材料结晶度的影响

摘要

对基于超高分子量聚乙烯（UHMWPE）和聚四氟乙烯（PTFE）以及准结晶填料Al–Cu–Fe的复合样品进行了X射线衍射（XRD）分析。具有不同填料浓度的样品经受摩擦。基于XRD数据确定聚合物基体的结晶度的变化。比较以对称扫描模式和掠入射几何学记录的衍射图样，表明表面层和样品块的结构有所不同。
