Abstract
Disclosed is a thermosetting resin composition for steel inserts, the composition including a thermosetting resin composite and a glass fiber. The thermosetting resin composite preferably includes 100 PHR of an unsaturated polyester resin, about 30 to 40 PHR of a low shrinkage agent, about 5 to 8 PHR of a release agent, about 130 to 140 PHR of a filler, about 2 to 8 PHR of a thickening agent, and about 1 to 2 PHR of a curing agent, based on 100 PHR of the unsaturated polyester resin. The thermosetting resin composition provides reduced costs and weight as compared to a steel material composed of only steel, and also exhibits physical properties comparable to the steel material.
