| 摘要 |
The invention relates to a process for the manufacture of a tubular composite part whose longitudinal axis exhibits a curve and/or whose wall exhibits a variable cross section relative to the longitudinal axis in which process, a tubular semi-finished product, comprising an uncured or a partially cured resin and fibre reinforcement and further comprising an inflatable former, is introduced into a mould, a medium is brought into the inflatable former under pressure, the resin being cured and the composite part thus obtained being removed, characterized in that the fibre reinforcement comprises at least a knitted or braided sleeve. Composite parts according to the invention can be used in numerous applications where complex structural parts are required that combine high pressure-resistance, flexural, torsional and tensile strength. Such an application is sometimes referred to as a space frame. Examples are the supporting parts in a car body or in a boat or aircraft, in construction, rucksack frames, bicycle frames, lampposts and sports equipment, such as bobsleighs, etc. |
