carbon fiber

ok thank you. i am 18 and get overwhelmed with all the science so i tend to not understand it all right off the bat. sorry. but i will look into all that and see. the car will mostly be for the street. so there is not an easy way to get carbon or carbon/ kevlar bumpers. is there any way to have steel inside the carbon fiber. say for braces inside a hood? i thought i had seen manufactures doing this but with what i know now it seems like it would not work at least not for very long
