Description

technical field

[0001] The invention relates to a hybrid carbon fiber composite material and its preparation method and application, in particular to a hybrid carbon fiber composite material and a device for monitoring the strain and damage of a structure made of the hybrid carbon fiber composite material, and the composite material in the monitoring structure application of stress, strain and damage. Background technique

[0002] Carbon fiber has superior mechanical properties such as high specific strength and specific stiffness, its strength is about 10 times that of iron, and its density is only 1 / 4 to 1 / 5 of steel, and it has good durability and excellent corrosion resistance Therefore, it is widely used as a reinforcing or structural material in many fields. Usually, when used as a reinforcing material, carbon fiber is impregnated with resin (that is, carbon fiber is infiltrated with epoxy resin and then hardened), and made into a sheet, rod or grid shape. Carbon fib...
