アラミド繊維シート

Aramid Fiber Sheets are fiber sheets using aramid fibers for use in the repair and reinforcement of concrete structures. The sheets have characteristics including toughness and pliability, and their filaments are resistant to folding. They are affixed to existing concrete materials, and are further strengthened by bonding between the fibers using an impregnating adhesive resin. They exhibit the same effect as increasing the iron reinforcing bar amount using fiber reinforced plastic (FRP) forming.

Because the organic fibers are non-conducting, there will be no effects due to magnetic fields, and electrical disturbance will not be caused. 

Characteristics

  • Due to being non-conducting, the fiber sheets will be ideal for installation in locations where there is concern about electrical accidents, such as railways, subways, and electrical rooms.
  • Because fibers are arranged in two directions, a single application will realize reinforcement in both the lengthwise and breadthwise directions (in the case of the two-direction type).
  • The fiber sheets have outstanding workability, allowing installation in offices, etc. while employees are still present without requiring the use of heavy machinery.
  • The outstanding chemical stability makes the fiber sheets ideal for use in repair and reinforcement as salt damage measures and as acid and alkali resistance measures.

Application Example

One-direction type

  • Seismic reinforcement for railway and road bridge piers and structural columns
  • Reinforcement of bridge beams, structural crossbeams and structural slabs
  • Floor slab durability improvement

Two-direction type

  • Tunnel lining peeling prevention
  • Elevated concrete bridge repairs
  • Concrete structure cracking and peeling measures
