Abstract

The invention discloses a method for testing the compression performance of a carbon-fiber reinforced resin-based thin-wall composite pipe. A mechanical compression testing piece of the carbon-fiber reinforced resin-based thin-wall composite pipe is prepared with the cementing connection technology. Firstly, the compression testing piece is installed and clamped on a mechanical testing machine; secondly, the compression testing piece is loaded; finally, a breaking load and the corresponding deformation value are obtained. By means of the method, the problem that an existing mechanical performance testing method of a carbon-fiber reinforced resin-based composite pipe material is not suitable for the thin-wall composite pipe is solved, buckling failure of the pipe in the testing process is avoided with a novel compression test piece preparing method, and a new test method is provided for the carbon-fiber thin-wall composite pipe. The practical compression performance of the carbon-fiber reinforced resin-based thin-wall composite pipe can be reliably reflected with the method.

Description

technical field

[0001] The invention relates to a method for testing the compression properties of carbon fiber reinforced resin-based composite material pipe fittings, which is suitable for measuring carbon fiber reinforced composite pipes with a wall thickness less than 1.5mm (nominal diameter less than 50mm) and a ratio of diameter to wall thickness greater than 50 (nominal diameter is 50mm-100mm). The invention relates to the mechanical properties of thin-walled pipe fittings made of resin-based composite materials, and belongs to the field of structural performance testing of carbon fiber-reinforced resin-based composite materials. Background technique

[0002] Carbon fiber reinforced resin matrix composite material rod and tube structure is a typical unit of composite material components. It is a commonly used structural component in aviation and spacecraft structures. Most large satellite antenna brackets use carbon fiber reinforced resin matrix composite material pipe...
