Abstract: The characteristic analysis of erosion of NB31 carbon-fiber composite enables the proposal of a novel carbon-fiber composite structure having a distinctly reduced erosion rate. Improvement only relates to the arrangement of the sewing and web fibers and to maintaining the structure of the pitch/carbon fibers, which consist of the main NB31 heat conducting components. The sewing and web fibers of the improved structure reinforce the rigidness/reinforce the thermal shield, compared to the NB31. The improved structure improves the erosion rate so it is 4-5 times lower compared to that of NB31.

Abstract: A plate-shaped carbon fiber composite with an impact surface that is exposed to a particle flux. The plate-shaped carbon fiber composite includes a base fabric in a carbon matrix. The base fabric has pitch fibers that are substantially perpendicular to the impact surface and second fibers disposed at an angle with respect to the impact surface that is between 0° and 90°.
