  • Patent number: 8525031
    Abstract: A low cost, high performance flexible reinforcement member that can be used for both optical and copper communications cable. The reinforcement members made according to the preferred process are more rigid than known reinforcement members, but are less rigid than glass pultruded rods. Communications cables utilizing these members are lightweight and exhibit an improved combination of strength and flexibility compared to traditional communications cables. Further, these communication cables may then be installed into underground ducts using more economical and faster installation techniques.

  • Patent number: 8486527
    Abstract: Fiber reinforcement rods having a combination of reinforcing fiber members coated with a UV curable vinyl ester resin material and a polybutylene terephthalate/polyether glycol or ethylene acrylic acid topcoat layer. The reinforcing fiber members may be S-type fiber members, E-type glass fiber members, a combination thereof, or E-type glass fiber members and/or S-type glass fiber members with high strength synthetic strands of poly (p-phenylene 2,6 benzoisoxazole fiber members. The topcoat layer provides enhanced properties of specific adhesion, enhanced environmental protection, resistance to surface fiber breakage, and to some degree resistance from delamination.

  • Publication number: 20030091299
    Abstract: A premise cable having a plurality of inorganic fibers for protecting and suspending a plurality of optical fibers within a polymer jacket. The inorganic fibers, preferably fiberglass fibers, do not generate smoke or fire and thus offer an improvement over traditional polyaramid fibers used as reinforcement materials in premise cables. A sizing composition is applied to the inorganic fibers to prevent ribbonization of the inorganic fibers, thereby preventing attenuation of the optical fibers caused by such a ribbonization and also allowing a uniform distribution of fiberglass fibers around the optical fibers to further protect the optical fibers.

  • Publication number: 20030082380
    Abstract: Fiber reinforcement rods having a combination of reinforcing fiber members coated with a UV curable vinyl ester resin material and a polybutylene terephthalate/polyether glycol or ethylene acrylic acid topcoat layer. The reinforcing fiber members may be S-type fiber members, E-type glass fiber members, a combination thereof, or E-type glass fiber members and/or S-type glass fiber members with high strength synthetic strands of poly(p-phenylene 2,6 benzoisoxazole fiber members. The topcoat layer provides enhanced properties of specific adhesion, enhanced environmental protection, resistance to surface fiber breakage, and to some degree resistance from delamination. The fiber reinforcement rod permits higher translation of strain energy due to reduced defects and residual stresses to allow a tougher and more resilient cured composite rod to be used.
