Abstract

The invention relates to a nondestructive detection method of the storage ageing performance of a propellant / liner bonding interface, used for spaceflight fuel nondestructive detection. The method comprises the following steps: sample preparation and parameter detection, data analysis and mathematic modeling, and parameter calculation and data processing, wherein the sample preparation and parameter detection step comprises contrastive sample preparation and contrast parameter establishment which are used for macroscopic detection, and detection sample preparation and infrared spectrum detection which are used for microanalysis; infrared spectrogram analysis and establishment of a mathematical relationship are carried out in the data analysis and mathematic modeling step; and in the parameter calculation and data processing step, peak separation software of an infrared spectrometer is used to acquire data, and the data is substituted to the mathematical relationship, and parameter calculation is carried out to acquire a performance parameter. The method adopts a tiny amount sampling mode, infrared spectrum detection and mathematic modeling to realize spectrogram analysis and data processing in order to obtain the bonding performance index of the propellant / liner bonding interface. The method has the characteristics of convenient detection process, good data repeatability, reliable parameter analysis and optimal data processing.

Description

technical field

[0001] The invention relates to a material non-destructive testing technology in the polymer chemistry field of aerospace fuel, in particular to a non-destructive testing method for the storage aging performance of the propellant / liner bonding interface. Background technique

[0002] Usually, the performance evaluation indexes of nitrate plasticized polyether NEPE propellant / liner bonding interface include bonding performance, bonding deterioration parameters, storage performance and storage life, etc. The evaluation method in the prior art mainly involves two aspects, the test specimen and the evaluation parameter. The test specimen is a standard rectangular specimen, and the evaluation parameter is the tear-off strength, that is, the "standard rectangular specimen tear-off strength evaluation method". This method has limited applicable objects and macroscopic evaluation parameters, and has certain advantages for formula development and product selection of ...
