Adhesion test of resin-infused basalt fibers for wind energy applications

Rotor wind blades are principally made of E-glass fibers reinforcement into an epoxy resin. This fibers have already reached the limit of their mechanical properties, therefore new materials are needed.

The main activity of Global Basalt Engineering LLC is creation of effective productions on release of continuous basalt fiber (СBF) with technologies of the last generation and composites on the basis of СBF (Basalt Fiber-Reinforced Polymer Composites as BFRP).

On one hand, carbon fibers offer a higher level in both stiffness and strength, but come at a significantly higher price. Basalt fibers, on the other hand, represent a viable alternative to E-glass, with better mechanical properties at a comparable price.

The strength of basalt fibers can be fruitfully used in wind energy applications if the strength of the fibers is transmitted to the matrix. Therefore, the fiber-matrix-adhesion is a crucial parameter that characterize the composite’s quality. The aim of this paper is to present the possibility for different tests methods concerning fiber-matrix-adhesion.
