Treść
The aim of the work was to improve the thermal and electrical conductivities of CFRP by enhancement of epoxy matrix thermal and electrical properties. To achieve the goal multi-wall carbon nanotubes (CNTs) were applied as a filler. CNTs were dispersed in epoxy resin using three roll milling. Nanocomposites with weight amount varied from 0.05 to 1% were fabricated and studied. Scanning and transmission electron microscopies were used for CNTs dispersion control. Thermal diffusivity and electrical conductivity were also measured. Rheological parameters, such as viscosity, storage and loss modulus were tested. CNTs significantly increase the viscosity of neat epoxy, what makes difficult the infiltration of carbon fibres. An addition of solvent was applied for decreasing the viscosity of epoxy with CNTs. Influence of the solvent on thermal and electrical conductivity, as well as mechanical properties was investigated. Application of CNTs increases the thermal and electrical conductivity, mechanical properties, however decreases the curing time and viscosity.
