Motor vehicle body parts

Automotive body parts (doors, hoods, roofs, trunks), in addition to mechanical strength, must have low weight, corrosion resistance, and excellent paintability. FRP (fiberglass) composites with isophthalic polyester resin or epoxy resin are suitable alternatives to steel sheets. The production process is carried out by hand lay-up for low volumes and SMC or RTM for high volumes. The produced panels have a perfectly smooth, void-free surface that reduces the need for puttying before painting.

In terms of performance, a composite body has higher resistance to stone chips and surface scratches and never rusts. Additionally, the vibration-damping ability reduces cabin noise. In racing cars and electric vehicles, body weight reduction helps increase acceleration and battery range. Alborz Organic Materials Company supplies low-smoke, self-extinguishing resins (to meet fire safety standards) as well as epoxy adhesives for bonding body panels.
