Mathematical analysis of burning process of polyester compositions using Numajiri—Furukawa method
Abstract
Fire features of the materials, useful for an assessment of the possibility of these materials applications in various fields, were characterized. Special attention has been paid to heat release rate (HRR) and burning index (BI) related to HRR. The way of description of the experimental HRR curves (HRRexp) using Numajiri-Furukawa method [equations (1)-(5), Fig. 1] was presented. HRRexp curves of polyester resin (PES) samples, unmodified and modified with addition (7,14 and 21 wt. % Of MoO3) acting as fire retardant (Fig. 2a-d), were determined. Using Numajiri-Furukawa method, B1 values (Table 1 and 2) were determined from the HRRexp curves. MoO3 addition to PES causes that BI values of modified PES decrease in comparison with BI of unmodified sample. Addition Of MoO3 in the amount of 21 wt. %, causes 45% decrease in BI.
