Abstract
This invention relates to an improved termination connection for advanced fiber composite cables of the type comprised of fibers fixed in a matrix binder. In particular, the composite cable is provided with one or more ribs of tension wound binder impregnated fiber cured on the end portion thereof. Potting material is secured over the ribs at the end of the cable preferably having a parabolically curved outwardly tapered contour to distribute the longitudinal and transverse forces over the fibers in the cable.
Claims17
A high tensile strength composite cord of the type comprising a plurality of substantially longitudinal fibers fixed in a resin matrix and having a relatively smooth outer surface wherein said composite cord includes a connection termination near one end thereof for being connected to a supporting structure and transferring tensile forces thereto, said connection termination comprising:
- at least one rib formed of overlapping layers of fiber fixed in a resin matrix and wound around and bonded to the outer surface of a connection portion of said composite rod near said one end thereof;
- and
- plug means secured to said at least one rib and to said connection portion of the composite cord for connecting to the supporting structure and transferring tensile forces thereto.
A cable comprising a plurality of high tensile strength composite rods of the type comprising a plurality of substantially longitudinal fibers fixed in a resin matrix and having a relatively smooth outer surface wherein said cable includes a connection termination near one end of each of said composite rods for being connected to a supporting structure and transferring tensile forces thereto, said connection termination comprising:
- at least one rib on the outer surfaces of some of said composite rods along a connection portion thereof near said one end of each of said composite rods, wherein said ribs are formed of overlapping layers of fiber fixed in a resin matrix and wound around and bonded to the outer surfaces of said connection portion of said composite rods;
- and
- plug means secured to each of said ribs and to said connection portions of said composite rods for connecting to the supporting structure and transferring tensile forces thereto.
A connection arrangement connecting one end of at least one composite rod to a supporting structure wherein said connection arrangement transfers tensile forces between said at least one composite rod and said supporting structure, said connection arrangement comprising;
- at least one composite rod formed of a plurality of substantially longitudinal fibers fixed in a resin matrix and having a relatively smooth outer surface and a connection portion near said one end thereof;
- at least one rib wound around the outer surface of said at least one composite rod along said connection portion wherein said at least one rib is formed of overlapping layers of fiber fixed in a resin matrix and thereby bonded to said at least one composite rod;
- a shoe connected to said supporting structure and overlying said connection portion of said at least one composite rod;
- and
- plug means secured to said at least one rib and to said connection portion of the at least one composite rod for connecting to said shoe.
