With the development of technology and the needs of society, the reinforcement technology of prestressed carbon fiber sheets has been increasingly widely used. The reinforcement support is an important component of connecting reinforcement components and prestressed carbon fiber board anchors, and its excellent performance will directly affect the tensioning effect and structural safety of prestressed carbon fiber board. This article uses the finite element analysis software ANSYS to simulate real components, preliminarily analyze the stress situation of the components, and optimize the design of the reinforcement support. It is verified through relevant experiments and has achieved good results in practical engineering applications
