Mafic, a producer of continuous and chopped basalt fiber as well as long fiber thermoplastic (LFT) resins, says that tests have proved the strength and stiffness of basalt fiber in composites.

According to the tests, which took place at the Western University in Canada, Mafic’s basalt fiber composite had a specific strength typically 50% higher and a specific stiffness 25% higher than similar glass composite.

Additionally, the interlaminar shear strength, a measure of the fiber matrix adhesion, was shown to be half way between similar glass and carbon composites in the same resin system.

‘We believe these results further demonstrate the value of basalt fiber,’ said Jeff Thompson, head of marketing at Mafic. ‘Our customers have seen fantastic results using our products; we are seeing expanding adoption of basalt where customers are looking to reduce mass, or improve stiffness and strength of their composite products without the costs of using carbon fiber.’
