摘要:
A method for non-destructively estimating a current physical condition of a cordage product in-service is described. The method involves obtaining sensor data associated with the cordage product while in-service handling a load. The sensor data includes any combination of cordage product elongation data, applied load data, and diametric data. The method further includes determining an axial stiffness value associated with the cordage product based on the sensor data and estimating a health state of the cordage product based on the determined axial stiffness value. The estimated health state is indicative of the current physical condition of the cordage product.
摘要:
A round sling system comprises a bearing structure, a cover, and at least one organizer secured to the cover. The bearing structure is arranged to define a plurality of loop portions and to define at least one bearing structure end portion. The cover defines a cover chamber. The at least one organizer is configured to engage the bearing structure such that the at least one organizer maintains a position of the bearing structure relative to the cover and the at least one organizer maintains a spatial relationship of the loop portions at least within the at least one bearing structure end portion.

A termination assembly for a composite rope structure comprising an end comprises a distal connection member and a proximal connection member. The distal connection member defines a first threaded surface and a working portion, where the working portion is adapted to be connected to a structure. The proximal connection member defines a second threaded surface, an internal surface, and a proximal opening. The first and second threaded surfaces are configured to engage each other to detachably attach the distal connection member and the proximal connection member. The internal surface of the proximal connection member is configured to engage the end of the composite rope structure to secure the composite rope structure relative to the proximal connection member.
摘要:
A rope structure (20) comprising a plurality of rope subcomponents (50), a plurality of bundles (40) combined to form the rope subcomponents (50), a plurality of first yarns (30) and a plurality of second yarns (32) combined to form the bundles (40). In one embodiment, the first yarns (30) have a tenacity of approximately 25-45 gpd and the second yarns (32) have a tenacity of approximately 6-22 gpd. In another embodiment, the first yarns (30) have a breaking elongation of approximately 2%-5% and the second yarns (32) have a breaking elongation of approximately 2%-12%.

摘要:
A rope structure comprising a plurality of formed composite strands. Each of the formed composite strands comprises fiber material and matrix material. The fiber material within the matrix material is twisted. The shapes of the plurality of formed composite strands are predetermined to facilitate combination of the plurality of composite strands into the rope structure.
