Abstract
Basalt fibre (BF) is a material made from extremely fine fibres of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is almost similar to its mineral fibre counterparts, like carbon fibre and glass fibre, having better physical mechanical properties than glass fibre, but being significantly cheaper than carbon fibre. In this study a series of investigations are conducted, to explore and develop other techniques which could be useful for basalt fibre finishing. The first investigation is piloted by qualitatively analysing the atomic element(s) composition of basalt fibre, with a use of Laser-Induced Breakdown Spectroscopy (LIBS). The inter-facial interaction relationship between basalt fibre, acids and alkalis is also explored as a means to determine the degree of BF resistance against corrosion. An attempt to modify BF surface properties is conducted by means of IR laser (CO2 laser) irradiation. A degree of BF surface damage due to different CO2 laser beam intensity levels is classified accordingly. An attempt to deposit carbon on BF surface, by IR laser method is explored. Lastly, a carbon matrix (C-matrix) is prepared from different concentrates of sucrose solution. This C-matrix is then used as a binding resin for BF reinforced composite material. Porous carbon composites rods (carbon electrode) are produced and tested for electrical conductivity, mechanical properties and thermo stability. To assess and evaluate properties of the specimens prepared, the following instruments are used: Scanning Electron microscopy (SEM), Tera 2300 mechanical tester, X-ray florescence (XRF), and Dynamic mechanical analyser (DMA).
