| Description |
It was investigated the influence of organic fiber Lola on the abrasive wear resistance of the aromatic polyamide of phenylone С-1 in the article. The increase of wear resistance of the materials which work in aggressive conditions is an actual task of the tribology of polymers, because the main reason of the machines out of operation isn’t their breaking but the wear of tools and moving connections. The spending on the elimination of premature wear reaches 2% of the gross national product in the industrially developed countries, and the spending on friction is up to 30% of used energy all over the world. That’s why it leads to the huge expenses on the machines’ repair, decreased productivity and increase in energy consumption. The using of chemical fibers gives an opportunity to solve two problems at once: to reduce the cost price of products (reduction of energy consumption for their manufacture), to increase their reliability and durability, cheapening of operation and repair herewith improving ecological situation during the production. It’s determined that filler has a positive impact on the tribological properties of the raw material such as the increase of abrasive wear resistance up to 34 – 56%. It was found the interconnection between the structure of polymer and its tribotechnical characteristics, since it’s known that physico-chemical and mechanical properties of the products from polymeric materials depend on the way of the mutual spatial arrangement of molecules, the character of their movement and the way of the spatial arrangement of associates which define the whole structure of the products. Thus, the discovering of the structure of polymers by the methods of X-ray diffraction has already become traditional and established among the main methods of the investigation of the structure of polymers. According to the results of X-ray diffraction analysis it’s determined that the introduction of the fiber to phenylone makes the degree of crystallinity increase. This is evidenced by the decrease of interplanar and the shortest interatomic distance by 6 and 7,5% respectively with simultaneous increase of the average size of the crystals by 15 – 24%. The investigation of the tribological properties and the structure of the developed organic plastics showed that the using of polyarylene fiber Lola as filler is perspective for the manufacture of machine parts and vehicle mechanisms, road and agricultural machines which work in the aggressive conditions.
Досліджено вплив вмісту термостійкого волокна лола на триботехнічні характеристики органопластиків на основі ароматичного поліаміду фенілону С-1. Випробування на абразив показало, що зі збільшенням кількості наповнювача в в’яжучому інтенсивність абразивного зношування знижається на 34 – 56 %, сягаючи мінімальних значень в інтервалі від 10 до 15 мас.% волокна. Встановлений взаємозв’язок, між структурою органопластиків та його трибологічними властивостями: введення волокна сприяє утворенню впорядкованої структури. |
