  • High-strength cable
    Patent number: 8240119
    Abstract: A high-strength cable having a twisted layer of non-metallic reinforcing elements in outer coatings is disclosed. The reinforcing elements include coating elements, fiber elements of copolyparaphenylene-3,4?-oxydiphenyleneterephthalic amide disposed in the coating elements, and filling materials filled between the fiber elements, respectively. The lateral compression stress of the fiber elements of the copolyparaphenylene-3,4?-oxydiphenyleneterephthalic amide is 75 cN/dtex or more.

  • Heat-resistant synthetic fiber sheet
    Patent number: 7026033
    Abstract: A heat-resistant fiber paper-like sheet comprises 40 to 97% by mass of heat-resistant organic synthetic polymers staple fibers, 3 to 60% by mass of heat resistant organic synthetic polymer fibrid and or an organic resin binder, in a portion of the staple fibers, each staple fiber having two flat end faces having an inclining angle of 10 degrees or more from a plane crossing the fiber axis at a right angles, and is useful as a base material for laminate materials for electrical circuit boards.
