Abstract
A marine fender has high bonding strength between a high-slip synthetic resin plate such as an ultrahigh-molecular-weight polyethylene plate and a rubber fender member, and quite long life-time of the high-slip synthetic resin plate. The high-slip synthetic resin plate and a rubber layer are previously welded to each other. The high-slip synthetic resin with the rubber layer and the rubber fender member are welded to each other by vulcanization. In this way, the marine fender is made.
Claims6
A marine fender comprising:
- a rubber fender member;
- and
- a high-slip synthetic resin plate fixed at least at a part of an outer surface of said rubber fender member, said high-slip synthetic resin plate having a rubber layer welded to a rear surface thereof and said rubber layer being bonded directly to the outer surface of the rubber fender member by vulcanization.
A marine fender comprising:
- a rubber fender member;
- and
- a high-slip synthetic resin plate fixed at least at a part of an outer surface of said rubber fender member, said high-slip synthetic resin plate having a rubber layer welded to a rear surface thereof and said rubber layer being bonded to the outer surface of the rubber fender member by vulcanization, said rubber layer having a surface bonded to the rubber fender member, which is roughened by buff or canvas to thereby increase a bonding strength between the rubber layer and the rubber fender member.
