Mechanical properties and mechanism of wollastonite fibers reinforced ...
Wollastonite is a naturally occurring silicate fiber. The chemical formula of wollastonite is Ca[Si 3 O 9]. Most wollastonite fibers are acicular, fibrous or granular, and wollastonite aggregates are usually bundled, radial or very large [19]. The main components of wollastonite include silica (SiO 2), calcium oxide (CaO) and alumina (Al 2 O 3).
