The titanium honeycomb structures were prepared by TC4 titanium alloy foil with thickness of 0.1 mm and TA1 industrial pure titanium foil with thickness of 0.05

0.10 and 0.15 mm.The flat pressure tests of titanium honeycomb structures were carried out.The effects of foil thickness and side length of honeycomb hole on the bearing capacity of titanium honeycomb structures were analyzed by combining with the failure forms of honeycomb structures.The experimental results show that with foil thickness of titanium honeycomb increase and honeycomb hole side length decrease

the bearing capacity of titanium honeycomb structure is increased

meanwhile

the bearing capacity of TC4 titanium alloy honeycomb structure is significantly higher than that of TA1 industrial pure titanium honeycomb structure.The collapse areas of all structural parts appear in the unwelded joints in the middle

and the failure form is charaderized by local plastic deformation with cracks.
