Difference between pre-stress CFRP plate and carbon strip
The carbon fiber strip and prestressed CFRP plate are all carbon fiber strip in the final analysis. The difference between the two is from the different reinforcement methods they belong to.The reinforcement methods of carbon fiber cloth and carbon fiber strip are all passive reinforcement, and the prestressed CFRP plate is the active reinforcement.

Drawing test of epoxy anchoring adhesive
Drawing test is the most effective method to test the effect of rebar planting. The HM-500 injection type rebar adhesive is 100% through the experiment or on the spot.

Reinforcement of Pre-stressed CFRP plate
Prestressed carbon fiber plate strengthening technology is a kind of active reinforcement technology applied to bridge and long-span beam and other flexural members. It is popular because of its advantages of not increasing self weight and unloading.

Carbon fiber fabric
In view of durability and safety considerations, the raw material for structural reinforcement carbon cloth is polyacrylonitrile fiber (PAN).The unidirectional carbon fiber fabric used for structural reinforcement is easily soaked by adhesive and is generally used in 12K small tow knitting and 24K small tow knitting.

Strengthening technique with carbon fiber fabric
Unidirectional carbon fiber fabric is used for beam and slab flexural reinforcement, and beam, column, wall shear reinforcement, confined concrete for seismic strengthening of columns, also for crack repair and dynamic load member reinforcement, reinforcement and repair.

Concrete structure unsuitable for carbon fiber strengthening
Carbon fiber reinforced polymer(CFRP) wrap can be successfully used for concrete structure, seismic shear and flexural strengthening. But it should be pointed out that because many inherent characteristics of CFRP reinforcement structure, many concrete structures are not suitable for strengthening with carbon fiber, so it is necessary to analyze their applicability.

Carbon fiber reinforced polymer(CFRP) plate strengthening
1 layers of carbon fiber reinforced polymer(CFRP) laminate is equivalent to 4-8 layers of carbon fiber reinforced polymer(CFRP) fabric.Low cost,cost effective compared with other retrofitting method.Light weight, no influence to original structure

Pre-stressed CFRP laminate improve the flexural rigidity
1.The prestressed CFRP plate makes the concrete(because of the crack is out of work) in the lower part become the effective section

Prestressed CFRP laminate
The high strength properties of CFRP (carbon fiber reinforced polymer) can be brought into play in advance, and there will be greater strain before the two force, which can effectively reduce or even eliminate the phenomenon of CFRP sheet strain lag, and achieve better reinforcement effect.
