Research On Infrared Thermal Image Detection Technology Of Honeycomb Sandwich Structure With Grid Panel For Spacecraft

Nondestructive testing is to quantitatively in the damaged component under the condition of master material properties of components,which allows the compliance and life evaluation, defect detection, the generated in the production process to be improved,in order to detect defects,improve the quality of products,to ensure the safe and reliable operation of equipment.This paper is mainly to solve the technical problems Aerospace product: The main problem to solve defect detection of carbon fiber honeycomb sandwich structure panels grid panel that exist, uneven loading, the existing problem of inadequate tooling itself. After a review of relevant literature, understand the characteristics of infrared detection technology, applications, theory and the latest research progress and status at home and abroad. At the same time the infrared thermal imaging technology prospects in the future. Through analysis, to understand the structure of honeycomb sandwich panels grid panel defect type and design of the standard sample pieces. Factors affecting infrared detection technology were analyzed, and experimental study verified the detection of tooling for the current problems were tooling design, implementation, automated detection, detection efficiency is improved. Saving testing time and costs.The infrared thermal imaging detection technology in theory in our country is relatively mature,but the application in space field is still in the initial stage.So research spacecraft with infrared therm ography mesh honeycomb panel structures play an important role in improving the quality of products.
