FRP composite strengthening

FRP reinforcement systems apply fiber fabrics to the surfaces of buildings, bridges, and other structural members to improve structural performance. After installation, the fiber reinforced system will provide excellent long-term physical and mechanical properties.

Structrual strengthening fabric

Fiber Reinforced Polymer (FRP) Fabrics

Fabric reinforcement system, also known as carbon fiber reinforced polymer (CFRP) system, consists of woven or stitched unidirectional carbon fibers and impregnated resin. This unique combination makes it a versatile material that can be used in many applications. Including restrictions, shear and seismic upgrades and reinforcement of weak concrete, masonry, natural stone and wood structures.

Horse FRP structural reinforcement system has many advantages

Long-term performance in different applications and environments.
Reinforce irregularly shaped structures and substrates.
Installation is extremely flexible and easy, ensuring minimum downtime.


Typical structural application of carbon fiber reinforcement

Confinement
For structural members under compression
Enhanced carrying capacity or ductility
Multi-layer applications are possible

Enhanced shear
Non-rectangular cross-section is possible
Use anchor

Seismic reinforcement
For passive reinforcement solutions
Used as a substitute for textile reinforced mortar

Weak matrix reinforcement
Used to strengthen masonry, natural stone walls and other structures
Flexural reinforcement of weak concrete members or structures

Advanced FRP composite reinforcement

Advanced frp composite

Because the epidemic of new coronary pneumonia has never ended, Horse Construction has no way to conduct offline exchange seminars. After a series of discussions, it was decided to start an online seminar on carbon fiber reinforced materials.

Our Dr. Tan mainly conducts seminars and answers to clients.

In the webinar, we are very happy to participate in the Q & A session. These are the classic question-and-answer sets of the online conference.

1.
Q: Improve the beam's bending and shear resistance?
A: If using FRP composite to increase the flexural strength, it is recommended to check the shear force of the component. U-shaped packaging can be used to provide beam shear reinforcement

2.
Q: When considering the use of FRP, is it necessary to conduct "pre-inspection" and maintainability inspection (deflection, vibration, etc.)?
A: Once you have designed a preliminary reinforcement solution, you can check it. Contains some maintainability checks on concrete, steel and FRP.

3.
Q: Are these strengthening limits only gravity loads? What about seismic load combinations?
A: Yes, the reinforcement limit applies only to gravity loads. Earthquake loads do not require an existing bearing capacity check, because FRP is highly unlikely to be damaged in a lateral event.

4.
Q: Do any of your seminars cover FRP and seismic applications?
A: Yes, both offline and online seminars will talk about these

Retrofitting by CFRP laminates



CFRP Laminate Strengthening

• Short construction period

• No maintenance required

• Easy installation, low installation cost

• Light weight, no influence to original structure

• Corrosion resistance, long-term effect of 50 years

• Cost effective compared with other retrofitting method

• 1 layers of CFRP plate is equivalent to 4-8 layers of CFRP fabric
