Piece of metal matrix composite high rigidity and high stability in a longitudinal direction material.

摘要

An elongated piece, COMPOSITE WITH METAL MATRIX, respectively comprises between 35% and 45% by volume of alloy matrix with aluminum or magnesium, and between 65% and 55% fiber volume ONGOING CARBON PARALLEL TO layered length. At least about 90% of the carbon fibers are fibers with a module ULTRA HIGH. IN BETWEEN 25% AND 60% OF LAYERS, these fibers are oriented at 0 ° +/- 5 ° to the longitudinal direction of the piece when the matrix is ​​aluminum base. IN OTHER COATS, THEN ARE ORIENTED FIBERS BETWEEN +/- 20 ° to +/- 40 ° to this direction. WHEN THE WOMB IS BASED MAGNESIUM FIBER MODULE WITH ULTRA HIGH 0 ° are aimed at +/- 5 ° by at least 90% of the layers. This results in a high rigidity and high stability at the above address, favoring the applications in the space industry.
