Study on Flame Retardant Vinyl Ester Resin Matrix Composites

A flame retardant vinyl ester resin and its composites is studied. The vinyl ester resin is prepared with a cross linker which has the flame retardant characteristics instead of styrene. The curing process is given by the determining the gel time, viscosity and reaction activity. The mechanical property and flame retardant property of the vinyl ester resin and its composites is tested. The result shows that the flame retardant property of the resin and its composites increases greatly when the mechanical property is constant. The limit oxygen index of the composites is 30.6 and it has flame retardant property.
