Prestressed carbon fiber plate uses continuous carbon fiber filaments as raw material. After high-temperature curing through pultrusion process, prestress is applied through professional tensioning equipment to form a "active stress" reinforcement system. The product has a tensile strength of more than 2800MPa, an elastic modulus of about 165GPa, and a density of only 1.6g/cm³, achieving a reinforcement effect far exceeding that of ordinary carbon fiber plates while being lightweight.

In the field of building and bridge reinforcement, prestressed carbon fiber plates are mainly used for flexural reinforcement of heavy-duty components such as long-span beams, continuous beams and bridge webs. Compared with ordinary carbon fiber reinforcement, prestressed technology can actively offset part of the structural self-weight and load stress, greatly improve the yield bearing capacity of components, effectively control structural deformation and crack width, and is especially suitable for engineering scenarios with extremely high requirements for bearing capacity and rigidity. During construction, the "tension + bonding" process is adopted. After the plate is tensioned to the design stress, it is pasted on the tensile zone of concrete to form a synergistic stress system with the base material. The process is mature and reliable, and the reinforcement effect is significant.
