Purpose: The aim of this study is an investigation and comparison of mechanical properties of ceramic fibres after they were influenced by temperature and plasma treatment. Design/methodology/approach: Single filament after being processed at different temperatures (200oC, 400oC, 700oC and 1000oC) and methane plasma treatment was separated with a magnifier, prepared on a punched mounting tab, and was evaluated in accordance with Japanese Industrial Standard. Findings: Preliminary results of the improvement in tensile strength, Young’s modulus, elongation of ceramic fibres after plasma treatment are studied in this paper. Research limitations/implications: The samples were tested for optimized parameters of plasma modification and optimized parameters of plasma to ceramic fibres curing. There was not enough time to test the adhesion between Geopolymer matrices and ceramic fibres. Practical implications: In the future, our work will be focused on optimization of parameters for plasma modification of fibres made of different materials and applying this method to improve the fibre and Geopolymer matrix adhesion. Originality/value: The value of this work is defined by the influence of plasma treatment parameters on quality, mechanical properties of ceramic fibres and increasing the adhesion between matrices and reinforcements.
