摘要:
The rope of this invention comprises a plurality of strands each having a twisted reinforcing fiber bundle, thermosetting resin applied to the fiber bundle, and a thermoplastic resin cover enclosing the fiber bundle. Each strand in the rope is kept to substantially a round sectional shape by the twisted fiber bundle.The method for forming the rope comprises the steps of twisting the reinforcing fibers in such a manner that the tensile strength of the twisted fibers is not reduced to less than 50% of the fibers not twisted, applying an uncured thermosetting resin to the twisted fibers, covering the fibers with a molten thermoplastic resin, cooling the thermoplastic resin to cover the fibers with solidified thermoplastic resin and thereby forming a strand, forming a rope structure from a plurality of the strands, and heating the rope structure to cure the thermosetting resin applied on the fibers.
摘要:
In a strapping band comprising a tape-shaped core having continuous reinforcing fibers combined together with a thermosetting resin and an outer layer of thermoplastic resin covering the tape-shaped core, the thermoplastic and thermosetting resins each has polymeric units derived from the same monomer.
摘要:
A continuously supplied reinforcing material is impregnated with an uncured thermosetting resin and shaped into a predetermined sectional configuration, which is then covered with a forcibly extruded molten thermoplastic resin. The thermoplastic resin is immediately cooled to enclose the shaped fiber material with the solidified thermoplastic resin, and a thus continuously formed material is obtained.
