Description

technical field [0001] The invention relates to a composite material part and a manufacturing method thereof, more specifically to an annular guide ring and a supporting ring part of modified cloth phenolic material used in a hydraulic transmission system of a construction machine and a manufacturing method thereof. Background technique [0002] Various large and heavy-duty construction machinery, such as loaders, excavators, pile machines, etc., the friction parts such as guides, supports, and seals in the hydraulic transmission system are used in extremely harsh conditions. The load and lateral force are mixed with strong shock and vibration at the same time, and they are in the frictional movement with relatively harsh lubrication conditions. The mechanical and physical properties of these components are directly related to the service life of the hydraulic transmission system and affect the operation of the entire machine. At present, engineering plastics such as modifi...
