Surface accumulation layer 2 is that 60% fiber and 40% resin are formed by weight ratio.
Surface accumulation layer 2 is that 65% fiber and 35% resin are formed by weight ratio.
Surface accumulation layer 2 is that 70% fiber and 30% resin are formed by weight ratio.
Described fiber is the T700 fiber, and described resin is a SE-51 epoxy resin.
Advantage of the present invention is: fiber composite reinforced coupler of the present invention, enhancement layer has wherein adopted fiber, wear resistant resin with many excellent mechanical, physics, chemical property to be made, have good wear resistant friction reducing performance and outstanding impact strength, than the wear-resisting several times of metals such as general carbon steel, more wear-resisting more than 10 times than nylon 66, self lubricity is good, friction factor is extremely low, be difficult for adhering to foreign matter, not embrittlement has good heat stability, highly corrosion resistant, outstanding weatherability, the ageing resistance of height, characteristics such as high tenacity, proportion are little, in light weight.
