• In the areas of reinforced hconcrete : Good alkali resistance,high tensile strength.
Application prospects
• CBF has broad prospects in construction areas due to its high cost performance.It is said that it will bring a revolution to the construction materials.
• Excellent tensile strength:
3800~4800MPa,higher than other high technological fibres:carbon fiber、 steel fibre、 aramid fiber、glass fibre.
CBF’s principal properties compared with other fibres
Research at abroad
• Basal Fibre Association,BAF was founded in Texas,America,and greatly stimulated the research and development of CBF
Ukraine制造连续玄武岩纤维及绝缘材料生产联合体的流水线
Principal Properties
• Extraodinary good heat resistance: working temperture ranging from -269~700 ℃.80% of the initial strength under the temperature of 600 ℃.

Principal Properties
• Prominent Chemical Stability: due to the constituents ，KO,MeO and TiO,which strongly enhance the ability of chemical corrosion and water resistance.
• In 2019, China formally listed the research of continuous basalt fibres in the national 863 plan.
• 0n Dec,19,2019,GBF(横店集团上海俄金玄武 岩纤维有限公司)was founded mainly for the research and development of CBF. Now it has become the leading company in China in the field.
Concept
• Raw materials:natural eruptive rocks. • Manufacture: by heating the crushed rocks
to a temperature of about 1450~1500 ℃, then stretching to continuous filament with the spinneret plate.
