Abstract

ATL and AFP methods of automated placement are widely used worldwide to increase the productivity and accuracy of prepregs placement in manufacture of large PCM-based parts. However conventional prepregs are not always suitable for processing by these methods - they are subject to specific requirements in technological tack providing with precise fixation and orientation of layers and easy separation from backing paper. There is no standard method for the tack determination, so this article reviews various widely used in Russian and international industry tack determination methods, conclusions are made on their precision, efficiency and usability for different prepreg laying methods. The work was executed within implementation of the complex scientific direction 13.2. «Constructional PCM» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)
