Abstract (en)
[origin: WO2022229569A1] The invention relates to a method for manufacturing E-glass fibres having a target composition, comprising melting a mixture of raw materials constituting a melt, including at least one calcium source selected from a mixed oxide of calcium with at least one element selected from the group consisting of Si and Al, in particular a calcium silicate and/or an aluminium and calcium silicate, said calcium source or sources being natural mineral materials, i.e. unprocessed mineral materials originating from a natural geological environment.
