Carbon fiber resin newbie question
(OP)
Why are metallic resins never used as resin for carbon fibers? If I remember right carbon fiber has such a high melting point(boiling point really since it won't melt) that I would think almost any metal could be used as a resin.

Unlike polymers another benefit of reinforcing metals is that the density is usually reduced.
Predicting composite properties and designing with composites is much more complicated than with homogenous materials, but it is not impossible and the benefits make it well worth the effort.
Composites application growth could explode if we had a better set of rules for using anisotropic materials. Part of this is that the actual load vectors for many products are unknown, e.i. too much analysis stops with von Mises stresses.

As for why carbon fiber is not use in MMC, from the cost point of view, carbon fibers are much more expensive than glass fiber. Carbon fibers cost about $12/lb where glass fiber cost around $1/lb.
From the weight point of view, i would rather use a polymer matrix composite to achieve a more significant weight reduction than a Metal matrix composites.

Why are metallic resins never used as resin for carbon fibers? I would answer the question with question : How melting metal (several hundred or thousand grad) can be casted to the carbon fibers?
Remember : carbon is high degree temperature act as solid fuel, right? May be some technique can be developed for that, but it must be expensive.
cheers

The parts were not made with a liquid resin. The material was cold formed.
