[0002] Glass Fiber Cable Strengthening Core Aramid Fiber Cable Strengthening Core advantage: 1. Corrosion resistance, antistatic 2. Strong acid and alkali resistance 3. High tensile strength shortcoming: 1. Large bending radius advantage: 1. Higher tensile strength (≥1800MPa) 2. The bending radius is small (only for glass fiber optic cables half of the reinforcing core) 3. The weight is lighter (the density is the same as that of glass fiber optic cable half of the reinforcing core) 2. Slow production rate 3. Poor combination with surface sheath material 4. Anti-fracture (it can still be maintained in the case of breaking 1100MPa tensile strength) 5. Good combination with surface sheath material

Embodiment Construction

[0029] Such as image 3 As shown, pull out the aramid yarn from the creel (A), try to avoid fiber bruising and fiber fluffing, and to prevent the aramid yarn from being twisted together, thread the aramid yarn in a regular and orderly manner. The aramid yarn should be evenly distributed on the splitting roller. Pass each bundle of aramid yarn passing through the splitting roller through the mold (B), and there should be no phenomenon of broken ends not passing through.

[0030] To prepare resin raw materials, it should be fully stirred on the mixer, and the stirring time should not be less than 5 minutes. The stirred resin raw materials must be filtered through an 80-mesh sieve before being poured into the resin tank (C).

[0031] Set the temperatures of the curing area (D) and the shaping area (E) of the mold to 200±10°C and 140±10°C respectively, and heat the mold with electricity.

[0032] The aramid yarn is heated by the resin tank and the heating mold, and then shaped ...

Abstract

A fiber reinforced plastic pole with aramid fiber as reinforcing material and composed by thermosetting technology and thermoplast technology specifies a KFRP pole with continue length used for framework supporting in optical fiber cable. In device structure, use aramid fiber as reinforcing material, thermosetting resin as basal body, and thermoplast PE as sheath material; heat by special mould and form continue length by drawing work. The advantage is: tensile strength higher (larger than 1800MPa), bend radius less (half of strengthen core of glass fiber optic cable), mass lighter (density is half of that strengthen core of glass fiber optic cable), anti-fracture ( with 1100MPa tensile strength even broken) and has sheath material on surface need not extra adding.

Description

technical field [0001] Aramid fiber optic cable strength core is a high-performance non-metallic fiber optic cable strength core, which can be widely used in all-dielectric optical cables and indoor optical cables to play the role of skeleton support.
