ABSTRACT:
A method for the manufacture for the tubes or shafts of a composite material and having a low weight, whereby a blank of a material that can be pressformed and which has a substantially even thickness of material is subjected to isostatic pressing on or in a formation tool thereby providing a shell or a liner (15) of an intended shape and profile and having a mainly by substantially thickness of material, and on or in said shell or liner (15) another material is applied and is bound, for instance a highstrength material like glassfiber, carbon fiber or aramide fiber, so that the liner (15) and said other material (17) provide a solid integral composite tube or composite shaft. A tube made according to the method can be a barrel, whereby the liner (15) preferably has a conically shaped charged space and is formed with riffels in the race, which rifels have a progressively increased pitch in the direction towards the outer end of the barrel, and whereby the lower rifel portions on the outside of the liner (15) portions are filled with another material, and the liner is completely covered with preferably highstrength material having a low density, whereby the liner (15) and the other material or materials provide solid integral unit. Correspondingly a shaft can be formed with outer shaft shell of a material that can be pressformed and an inner filler material of a preferably highstrength material having a low density.
