Problems solved by technology
However, the carbon fiber / glass fiber composite core has a high modulus of elasticity and low elongation, and the outer layer of glass fiber is exposed, so it is prone to surface defects such as scratches or damage that should not be detected. If the size of the disc used is too small, it may cause the core Rod damaged or even broken

The invention discloses a composite material core rod reeling test machine comprising a protective cover, a sample importing apparatus, a reeling apparatus and a programmable controller. The sample importing apparatus and the reeling apparatus are arranged in the protective cover. The programmable controller is arranged on the outer side of the protective cover. The machine provided by the invention is characterized in that: 1, with the sample importing apparatus, a sample can be smoothly delivered along a preset direction, a constant tension is kept on the sample, such that the curvature radius of the reeled sample is constant with the outside diameter of a reeling wheel, and the precision and the reliability of the test can be ensured; 1, the reeling apparatus is advantaged in simple structure, simple operation, and automatic feeding; the rotary speed of a motor and the outside diameter of the reeling wheel can be adjusted according to requirements; therefore, the reeling test machine can be widely applied to samples of different specifications and types; 3, a programmable controller is adopted, configurations and automatic controlling can be carried out upon reeling tests with samples of various specifications and types, and test results can be calculated and presented.
Description
technical field [0001] The invention relates to a test device for materials used in transmission lines, in particular to a winding test device for a mandrel made of carbon fiber / glass fiber reinforced composite material, in particular to a carbon fiber / glass fiber reinforced composite mandrel winding test machine. Background technique [0002] Carbon fiber / glass fiber resin refers to a type of composite material composed of carbon fiber and glass fiber as a reinforcing phase mixed in a resin matrix phase, because of its high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance , Creep resistance, small sag and small thermal expansion coefficient and a series of excellent properties meet the requirements of the electric power industry for new-type transmission line stranded wire core materials, so carbon fiber / resin is used as the center layer and glass fiber / resin is used as the coating Layers of carbon fiber composi...
