Manufacturing of composites samples with graphene

Abstract

The article presents the state of knowledge within the scope of graphene production used in polymer matrices composites, as well as methods of obtaining graphene for these composites, including chemical method. The way of obtaining graphene in form of planes with dimensions of 90 x 100 mm and the method of manufacturing multilayer composite with graphene were presented. composites were produced from carbon fiber-epoxy resin prepregs in out of autoclave process. The adhesive film were used as an additional component which allows to transfer of graphene plane on carbon-epoxy resin prepregs and facilitate the consolidation process. In terms of the quality analysis of prepared composite samples results of ultrasonic tests of composites plate without the graphene and with graphene as an A-scan, B-scan, c-scan, S-scan were shown. The use of ultrasonic methods of registration: c-scan type amplitude of the echo and bottom echo signal amplitude,that allows to detect manufacturing defects caused by the mismatch of parallel edges of carbon prepregs, were engaged. The analysis of c-scan images allows to determine the accuracy of the angular orientation of the carbon layers. keywords: composite, graphene, composites with grapheme.
