ABSTRACT:
Elongated structural components having a cross-section such as of a letter of H, U, or T and made of carbon fibre-reinforced carbon are manufactured without employing specific dies correspondent to the aforementioned cross-section. A plurality of square tubes prepared simply by winding carbon fibres over a square mandrel and impregnating with adhesives, are bundled to a single block, wound with aramid fibres, and subjected to heating for the carbonization of the adhesives and consequently of said block of tubes. The carbonized block is cut along its longitudinal axes into a number of elongated pieces having the desired cross-section.
