Decreasing the Specific Amount of Metal in the Working Equipment of Road Machines Using of Polymer Composite Materials with a Honeycomb Filler

The problems of manufacturing the working equipment of road machines from polymer composite materials (PCMs) are considered. The design of a bulldozer blade made of carbon-filled plastic with a honeycomb filler is proposed. The use of PCM with a honeycomb filler in its design is shown to decrease the specific amount of metal per product and to provide adaptation of the working bodies to various categories of developed soils, which significantly increases the productivity of machines. A list and range of changing the adaptable blade parameters, which affect the resistance of the soil to digging and dragging, are given.
