FRP: What it really is..
FRP Definition,
as taken from “Fiberglass and Composite materials: An Enthusiast's Guide to High Performance Non-Metallic Materials for Automotive Racing and Marine use”
Until recently, this sub-category of composites was called fiber reinforced plastic- FRP for short- with various sub-sub-categories according to the particular kind of fiber employed, such as carbon fiber reinforced plastic (CFRP), aramid fiber reinforced plastic AFRP), and glass fiber reinforced plastic (GFRP). In common usage, GFRP is also known as “Fiberglass” which can be a bit confusing, because fibers by themselves, whether glass fibers or any other kind, are only half the story: the resin is the other half. Don’t make the mistake of thinking that fiberglass (GFRP) is the one thing and composites are another—fiberglass is a composite material. There are a couple of likely reasons for the term composite tending to replaced the term FRP. First fiberglass has been around several years before fibers were developed that were stronger and stiffer than glass fibers, and so could be worked – together with plastic resin – into composites that were also stronger and stiffer than those made with glass. To distinguish them from GFRP’s and to suggest their superiority, composites make using these new fibers were called advanced FRP composites, which soon got shortened to just composites.
The other reason may have to do with the idea implied by the second half of the expression “Reinforced Plastic” suggest that it is the plastic that is doing the job, and that the fibers just help a bit by reinforcing it. If there is only a small amount of fiber reinforcement, then the properties of the end product—the combination of plastic and fiber—will be closer to those of the plastic than to those of the fiber. On the other hand, if there is a lot of fiber and only a little plastic, the resulting combination will vastly outstrip the strength and stiffness of the plastic resin by itself. Though there is no hard dividing line, at some point the concept shifts from a piece of plastic whose strength and stiffness are improved somewhat by the inclusion of some strong fibers, to a material in which the mechanical properties begin to approach those of the fibers, and where the plastic exists simply to hold the fibers in place – the reinforcement provides the strength; the plastic provides the shape.
hope that helps clear things up on when a company says their body kit is FRP versus when a company says its made up of Fiberglass...same thing!

but how does it compare to carbon fiber, and other kits.

DAMN. talk about bringing up the dead.
its all about the atomic structure of Carbon and the way it is woven / laid (bi directional, cross hatched, layers, etc) versus the weaves of FRP (bi or uni-directional).
if u want more info.. buy the book.

by "atomic structure" you mean the electrostatic force of the covalent and van der waal forces due to the electron shielding of the 2p2 electron by the 2s2 level electrons which gives carbon is graphitic properties....
lol. I bought the book when I took organic Chemistry ;0)
