Zusammenfassung:	A polyurethane based filament winding resin reaction mixture, a resin bath and a filament winding apparatus are set forth. The reaction mixture comprises an isocyanate component including one or more isocyanates and an isocyanate-reactive component including from 5 wt % to 95 wt % of one of more polyols having a number acerage molecular weight from 50 g/mol to 8,000 g/mol, from 2 wt % to 30 wt % of one or more propane based triols, and from 1 wt % to 15 wt % of one or more trimester-phosphates, based on the total weight of the isocyanate-reactive component. A ratio of a total weight of the one or more propane based triols to a total weight of the one or more trimester-phosphates is between 1.1 and 5.0.
