Basalt fibres as reinforcement for composites

摘要: Introduction Basalt is a natural material that found in volcanic rocks. It mainly used (as crushed rock) construction, industrial and high way engineering. One can also melt basalt (1300-1700°C) spin it into fine fibres. [1-3,5-6,8] When as (continuous) fibres, reinforce new range of (plastic concrete matrix) composites. be combination with other reinforcements (e.g. basalt/carbon). [1,3] Some possible applications fibres basalt-based composites are: thermal sound insulation/protection wool, engine insulation), pipes, bars, fittings, fabrics, structural plastics, automotive parts, reinforcement (constructions), insulating plastics frictional materials. [1-8] This wide results from its good properties. has thermal, electrical replace asbestos almost all (insulation) since the former three times latter’s heat Furthermore, fibre diameter (comparable Eglass [5-6]) controlled order to prevent uptake harmful ultra-fine Because properties (10 better than E-glass, [5]), are incorporated printed circuit boards, resulting superior overall compared conventional components made fibreglass. electro technical such extra resistant insulation for cables underground ducts. already fire protection form fabrics or tapes [1,5-6,8].

Possible techniques involve prepregs, laying out, winding, direct pressure autoclaving, vacuum moulding [1,2,3]. Other, composite (such pipes rods) unidirectional reinforcement.
