Present paper deals with a mathematical programming model applied to the optimal design of oxide composition for glass fibres with low biopersistence.
The developed general model is applied on two case studies.
In the first case it is designed a composition for E glass type (boro-silicate glass). The result of modelling indicates a relatively low value of the carcinogenic index, KI, and therefore a high biopersistence.
In the second case study, the optimal model is applied to some glass fibres having chemical compositions in the frame of MgO-CaO-SrO-Al2O3-SiO2 oxide system.
The results of our modelling show that in this oxide system glass fibre with low biopersistence can be obtained and the values of the carcinogenic index around 39, are comparable with literature data.
