Sample clamping area assembling device suitable for composite material torsion experiment

The utility model discloses a sample clamping area assembling device suitable for a composite material torsion experiment. The sample clamping area assembling device comprises a composite material circular pipe, an external metal component and a metal inner supporting piece, according to the utility model, the composite material circular tube is clamped and fixed by changing the structure, so that the defects that the composite material circular tube still slips and the clamping area is damaged in the torsion loading process due to the fact that the connection between fiber cloth winding layers is not tight and the shape is not easy to fix caused by uneven force of traditional manual fiber cloth winding can be effectively eliminated. Hollow metal inner supporting pieces are connected into clamping areas at the two ends of the composite material circular tube, and the composite material circular tube torsion sample is constructed by externally connecting inner-circle and outer-hexagon metal components.
