Low-strain-rate compression experiment device in composite material plate

The invention belongs to the field of dynamic mechanical properties of materials, and particularly discloses a low-strain-rate compression experiment device in a composite material plate. The experiment device comprises a base, a first single-component force sensor, a compressible frame structure, a second single-component force sensor and an impacted plate which are connected in sequence; the compressible frame structure comprises a compression bottom plate, a compression top plate, positioning pipes and a chuck. The compression bottom plate is arranged above the first single-component forcesensor; the compression top plate is arranged below the second single-component force sensor; the compression bottom plate and the compression top plate are connected through a plurality of positioning pipes which are arranged in parallel; the chuck comprises a first clamp and a second clamp which are completely the same in structure, wherein the first clamp is arranged on the side, facing the compression top plate, of th
