General Information of CFCC

Outline of CFCC

Making the most of carbon fiber's excellent material properties, CFCC shows superior performances in terms of High Tensile Strength, Flexibility, Lightweight, High Corrosion Resistance, Non-Magnetism, and Low Linear Expansion in comparison with conventional cables. CFCC can be easily winded into a coil or onto a reel because of its stranded construction, thus can be applied as long span cables.

Notes on handling CFCC:
CFCC is a composite material consisting of carbon fibers and a matrix resin. As CFCC is different from steel members, special care should be taken; i.e. not to cause flaws, deformation or deterioration on handling. Especially, refrain from dropping hard and heavy objects (such as hammers) / sparking of welding/fire on CFCC, or bending CFCC steeply. CFCC damaged by any of these should be discarded.

Terminal Fixers

Terminal fixing methods currently applied for CFCC are roughly distinguished into 3 types shown below:

Resin filling method Type Symbol
Expansive material filling method For single cable (CFCC 1 pc.) ES
For multiple cables (CFCC more than 2 pcs.) EM
Wedge with buffer material method For single cable (CFCC 1 pc.) WS

Notes:
1. Assembly of CFCC and terminal fixers is to be done at Tokyo Rope factory.
2. Terminal fixing methods other than above-mentioned are under development to meet diversified usages.

Formed Parts

CFCC can be formed into various shapes at our factory.
These parts can be used as reinforcing members for concrete structures.
