The aim of this study was to assess the effect of adhesion between the non-polar, ultra-high molecular weight polyethylene (UHMWPE) matrix and the glass fiber fillers of various lengths treated with the commercially available "KH-550" agent, on the mechanical and tribological properties of the UHMWPE-based composites. The motivation was to find the optimal compositions of the polymer composite, for the compression sintering manufacturing of lining plates for the protection of marine venders and construction vehicles, as well as transport equipment. It was shown that the initial powder size at equal molecular weight determined the distribution patterns of the glass fibers in the matrix, and, as a consequence, the mechanical and tribological properties of the composites. Based on the obtained experimental data and the results of the calculation by a developed computer algorithm, control parameters were determined to give practical recommendations (polymer powder size and glass fiber length), for the production of the UHMWPE-composites having specified mechanical and tribological characteristics. The "GUR4022 + 10% LGF" composite, loaded with the chopped 3 mm glass fibers treated with the "KH-550", was recommended for severe operating conditions (high loads, including impact and abrasive wear). For mild operating conditions (including cases when the silane coupling agent could not be used), the "GUR2122 + 10% MGF" and "GUR2122 + 10% LGF" composites, based on the fine UHMWPE powder, were recommended. However, the cost and technological efficiency of the filler (flowability, dispersibility) and polymer powder processing should be taken into account, in addition to the specified mechanical and tribological properties.
本研究的目的是评估非极性超高分子量聚乙烯（UHMWPE）基体与经市售“KH-550”试剂处理的不同长度玻璃纤维填料之间的粘附力，对UHMWPE基复合材料的力学和摩擦学性能的影响。其动机是为保护船舶供应商、工程车辆以及运输设备的衬板的压缩烧结制造，找到聚合物复合材料的最佳组成。结果表明，在分子量相等的情况下，初始粉末尺寸决定了玻璃纤维在基体中的分布模式，进而决定了复合材料的力学和摩擦学性能。基于获得的实验数据和通过开发的计算机算法计算的结果，确定了控制参数，以给出关于生产具有特定力学和摩擦学特性的UHMWPE复合材料的实用建议（聚合物粉末尺寸和玻璃纤维长度）。对于恶劣运行条件（高负荷，包括冲击和磨料磨损），推荐使用负载经“KH-550”处理的3毫米短切玻璃纤维的“GUR4022 + 10% LGF”复合材料。对于温和运行条件（包括不能使用硅烷偶联剂的情况），推荐基于细UHMWPE粉末的“GUR2122 + 10% MGF”和“GUR2122 + 10% LGF”复合材料。然而，除了规定的力学和摩擦学性能外，还应考虑填料的成本和工艺效率（流动性、分散性）以及聚合物粉末的加工。
