Carbon fiber fabric for concrete structure strengthening

For general structure, carbon fiber fabric or precured carbon fiber plate can be selected according to the actual situation of the project. For long-span structures, heavy structures and other important structures, precured carbon fiber plate should be preferred and reinforcement measures should be taken.

Carbon fiber fabric for concrete structure strengthening

The carbon fiber fabric should be chosen according to the following principles for strengthening the concrete bearing structure.

1. For general structure, carbon fiber fabric or precured carbon fiber plate can be selected according to the actual situation of the project.

2. For long-span structures, heavy structures and other important structures, precured carbon fiber plate should be preferred and reinforcement measures should be taken.

3. Can't use prepreg carbon fiber fabric for reinforcing the load-bearing structure.

Suggestion: the number of layers of carbon fiber fabric with flexural members should not be more than 3 layers for 200g/m2 fabrics; the fabric for 300g/m2 should not be more than 2 layers and should not exceed 4 layers and 3 layers respectively. If it is necessary to increase the number of storeys, the design should be verified by load test.
