Dynamic drawing method and combined fixture for bonding force of fiber cement-based composite material

The invention discloses a dynamic drawing method and combined fixture for a bonding force of a fiber cement-based composite material, related to the technical field of fiber stretching fixtures. The dynamic drawing combined fixture for the bonding force of the fiber cement-based composite material comprises an impact bearing steel plate, a force transmission rod, a spring positioning guide rod, aspring, a spring pre-tightening fixture block, a leveling nut, a test piece fixing frame top plate, a test piece fixing frame bottom plate, a fixing frame pulling rod, a force sensor, an outer frame top plate, an outer frame bottom plate, an outer frame bracket rod, a ring type fixture, a laser displacement sensor, a laser reflection sheet, a winding roller shaft and a threaded rod support. The fixture belongs to a fiber dynamic stretching fixture, and can be used for detecting the interface bonding performance of the cement-based material matched with a drop hammer impact testing machine.
