Shell was made with naval brass at traditional water lubricate rubber bearing,but copper as strategic resource nowadays is expensive and rising increasingly,so phenolic resin as a new material.is now applied in water-lubricated bearing The fatal problem is that copper will be electrolytic corrosion.It influences bearings service life and use characteristics seriously.However,the new material phenolic resin possesses stable chemical property in water so there is no chemical interaction with other substances.Besides,it has many merits such as excellent shock resistance,low imbibition and so on.Phenolic resin is modified by choosing CNSL,polysulfone,Boron as modifier and adding other addition.Modified phenol resin is bonded to glass fiber by wet winding,for different glass fiber content groups of dates are obtained and then optimal constituent ratio is found.It owns good tensile-strength,compress strength,impact strength and minimum imbibition.It can be used as substitute material of naval brass shell and its Property can well satisfy the requirement of water lubricate bearing.
