KFRP

Aramid/Kevlar FRP(KFRP) Strength Member Reinforced Composite Materials for Fiber Optic Cables

KFRP reinforcement is a type of aramid reinforced plastic rod, which is different from aramid yarn. It is a rod-shaped material composed of aramid and polymer composites. The full English name is aramid fiber reinforced plastics. In the industry, aramid fibers are commonly referred to as Kevlar, so aramid reinforced materials are abbreviated as KFRP.

KFRP Process：


KFRP reinforcement is basically the same as that of GFRP reinforcement, except that the reinforcement material is changed to aramid yarn and suitable curing resin is selected.

Technical Performance：

In order to standardize the production and use of KFRP, in 2009, China formulated the product standard for KFRP fiber optic cable reinforcement (YD/T1181.3-2011).Table 3.4.3-2 presents the technical requirements for reinforcement components.

Note：①The requirements for the linear density index are applicable to KFRP models with diameters of 0.5 or 0.5/0.6, while the requirements for other models are yet to be confirmed.
② D represents the nominal body diameter of KFRP.

Feature：

·It is coated with adhesive resin on the surface of the body, and after the cable is formed, the KFRP reinforcement and the outer sheath of the optical cable are tightly bonded. Which allowing the tensile strength of the KFRP reinforcement to be fully utilized. It is not only has good flexibility, but also a certain degree of rigidity. It is arranged on both sides of the fiber optic cable. Which can effectively protect the fiber optic cable from being bent. When laying optical cables through pipes, not only traction but also push in methods can be used.

·It is a non-metallic material that can be reinforced with KFRP to form a butterfly shaped fiber optic cable with a full dielectric structure. Due to its non-metallic structure, optical cables have superior lightning protection performance. Which can effectively avoid the possibility of lightning entering the room during use. They are particularly suitable for situations where lightning is directly introduced from outdoors into the indoor environment.

·TOEM‘s KFRP does not contain harmful substances. And optical cables made with KFRP reinforcement can meet the requirements specified in the RoHS directive.
*All products can be customized according to your required parameters
