A Method of Increasing the Strength of Fiberglass

摘要

The study deals with the effects of the additives BeO, ZrO2, ZnO in various combinations and combined with Li2O, Fe2O3, B2O3 on the properties of glasses of the type MgO-CaO-SrO-Al2O3-SiO2. The increase in the chemical stability of the glasses and the increased strength of the fiber glass which results indirectly indicates structural strengthening and confirms the possibility of producing fiberglass of greater strength. The replacement of CaO and MgO by the additives lowers the temperature of the upper limit of crystallization, and this makes it possible to produce fiberglass of greater strength by ordinary technological methods.
