The use of image analysis for the study of interfacial bonding in solid composite propellant

Abstract

In the framework of this research, the program Image Pro Plus was applied for determining the polymer-oxidizer interactions in HTPB-based composite propellants. In order to improve the interactions, different bonding agents were used, and their efficiency was analyzed. The determination of the quantity, area and radius of non-bonded oxidizer crystals is presented. The position of formed cracks in the specimen and their area have a great influence on the mechanical properties of composite propellant. The preparation of the composite propellant in order to enable the photographing of their structure by means of stereoscopic and metallographic microscopes with the digital camera is also described as well. .

U okviru istraživanja program Image Pro Plus je primenjen za određivanje interakcija između polimera i oksidansa u kompozitnim gorivima na bazi HTPB. U cilju poboljšanja ovih interakcija, korišćeni su različiti vezujući agensi i analizirana je njihova efikasnost. U radu je takođe vršeno određivanje količine, udela, površine i prečnika čestica, koje nisu vezane za polimer. Površina formiranih pukotina i njihova raspodela u uzorku imaju veliki uticaj na mehanička svojstva kompozita. Priprema uzoraka kompozitnih goriva za snimanje njihove morfološke strukture pomoću stereomikroskopa i metalografskog mikroskopa sa digitalnom kamerom je takođe opisana. .
