Today, every car manufacturer prioritizes occupant safety. New standards are being established for occupant safety in various crash scenarios such as frontal head-on collisions, angle impacts, side impacts, rear impacts, and rollover. In today's world, fuel consumption is also a serious issue that must be addressed. With these constraints in mind, a lighter and stronger composite material than steel is used in car front rail. Using this material would aid in increasing fuel efficiency without jeopardizing vehicle safety. The traditional material used for car front subframe rails, steel, is replaced in this project with composite materials Carbon steel and Alloy steel hardox. CATIA V5 is used to create a 3D model of the subframe rail. For all materials, an impact analysis is performed in ANSYS14.0 to compare displacements and stresses at different speeds of 80 km/hr, 100 km/hr, and 120 km/hr.

Angle impacts, side impacts, rear impacts and rollovers, composite material, conventional material, Carbon steel and Alloy steel hardox.
