The aim of the work was to examine properties of hybrid composites reinforced with basalt fiber (BF) and polytetrafluoroethylene (PTFE) particles based on a polyoxymethylene matrix modified by silicon oil. In the experimental part the basic physico-mechanical properties were determined. Thermal and tribological properties were also investigated. To refer to the effects of reinforcement and determine the structure characteristics SEM images were taken. The addition of basalt fibers and PTFE particles in the amount of 7.5/7.5 wt% reduces the coefficient of friction (from 0.36 to 0.12) and the wear rate (from 0.61 to even 0.37) in relation to neat POM and increases the strength properties. An increase in the filler content to 12.5/12.5 wt% results in an almost twofold raise in stiffness from 2800 MPa to 5120 MPa for tensile, and from 2500 to 4944 MPa for flexural and causes a further reduction in wear rate without affecting on the friction coefficient. Studies have shown that the addition of filler allows to provide excellent tribological properties while maintaining high strength properties.

这项工作的目的是研究基于硅油改性的聚甲醛基体的玄武岩纤维（BF）和聚四氟乙烯（PTFE）颗粒增强的杂化复合材料的性能。在实验部分，确定了基本的物理力学性能。还研究了热学和摩擦学性质。为了参考增强作用并确定结构特征，拍摄了SEM图像。相对于纯净的POM，玄武岩纤维和PTFE颗粒的添加量为7.5 / 7.5 wt％可以降低摩擦系数（从0.36到0.12）和磨损率（从0.61甚至是0.37），并提高强度特性。填料含量增加到12.5 / 12.5 wt％时，抗拉强度从2800 MPa升高到5120 MPa，几乎增加了两倍。弯曲强度从2500 MPa降至4944 MPa，并导致磨损率进一步降低，而不会影响摩擦系数。研究表明，添加填料可以在保持高强度性能的同时提供出色的摩擦学性能。
