Method for measuring resistance of composite part

Abstract

The invention belongs to a resistance test value correction method, and relates to a method of rapidly realizing accurate measurement on the resistance of a composite part. The method for measuring the resistance of the composite part is characterized by comprising the following step of: step 1, by taking a measured contact point as a center, cleaning and polishing a paintcoat and floating glue on the surface of the composite part so as to expose an inner copper net; step 2, cementing two pieces of copper foil paper on the copper net with conductive glue; step 3, by taking the two pieces of copper foil paper as contact points, measuring the resistance. The method for measuring the resistance of the composite part is capable of rapidly and accurately measuring certain types of electromechanical resistance; on the premise that an airplane part structure is not changed, a pseudomorphic increase phenomenon of the resistance measurement value is eliminated, the actual measurement data is verified by virtue of twenty continuous airplanes, and the data is stable and normal.

Description

technical field [0001] The invention belongs to a method for correcting a resistance test value, and relates to a method for quickly and accurately measuring the resistance value of a composite material component. Background technique [0002] The composite material parts of a certain type of aircraft, especially the tail boom and flat tail, need to be measured for resistance after the parts are riveted due to the design function requirements. Because the measured contact point and the copper mesh of the effective resistance part inside the composite material are in the forming process Bonding a large number of non-metallic composite materials leads to an increase in the illusion of resistance, and each measurement data and the actual value (the actual value is within the tolerance range required by the theoretical data) drift, resulting in the illusion of data out-of-tolerance. Contents of the invention [0003] The purpose of the present invention is to propose a method ...
