Problems solved by technology

[0003] The resistance of the traditional resistive strain gauge will also change after receiving the tensile strain, but the ratio of the change rate of the resistance ratio (resistance change / initial resistance) to the strain is 2, that is, the sensitivity is 2, and the resistance change is quite weak, so it needs A digital bridge with high precision measures its resistance change

Abstract

The invention discloses a strain sensor made of carbon nanotube / epoxy resin composite material. The strain sensor comprises a strain body and conductors arranged at two ends of the strain body, wherein the strain body is made of the carbon nanotube / epoxy resin composite material, and the carbon nanotube / epoxy resin composite material mainly comprises an epoxy resin agent A, carbon nanotubes and a curing agent B. The strain sensor has the advantages that the ratio of the resistance change rate to the strain can reach above 20, the strain can be accurately measured without a digital electric bridge strain gauge extremely high in precision, and the strain sensor is high in sensitivity.

Description

technical field [0001] The invention relates to a carbon nanotube epoxy resin composite material strain sensor and a manufacturing process. Background technique [0002] Strain is a physical quantity that is often used in engineering practice. It is necessary to accurately measure strain in the fields of structural design, material research and development, and aerospace. There are many methods for strain measurement, such as non-contact optical measurement method, which is convenient and easy to operate, and the result display is intuitive, but the strain nephogram is rough and not accurate enough, so it is not suitable for occasions requiring high-precision strain measurement. The traditional method of accurately measuring strain is the electrical measurement method, which can obtain the strain value of a certain point more accurately, and the required components are resistive strain gauges and strain gauges. Strain gauges are generally composed of sensitive grids, base m...
