does anyone know how to calculate the longitudinal strength of carbon-fiber epoxy matrix?

Try looking up similar materials in Matweb. They usually quote standard test values.

Make sure you know the orientation and % of carbon fibre as this will impact greatly on material properties. ie, pay attention to the grain of the material, if applicable. If the material has a grain, then two strengths will be quoted:

Parallel to grain yield and perpendicular to grain yield (like wood).

Hope this helps. Paul.

You being a little vague, you want to know the modulus of elasticity or what?

Normally strength coefficients, like yield are determined by experiment.
