Abstract

This paper presents the results of a study of the characteristics and microstructure of samples of cold-curing polymer syntactic filler grade VPZ-25. Based on the results of testing the samples, a comparative analysis of the characteristics of VPZ-25 with the characteristics of a foreign analogue of cold-curing polymer filler was performed. Based on the results of preliminary testing of VPZ-25, a technology for filling honeycomb panels with VPZ-25 polymer filler for aircraft components was developed under various conditions.
