Abstract

When tubular bodies are to be used in telescopic hydraulic systems, strict requirements as to surface smoothness and accurate dimensions are made. Such a tubular body of fiber reinforced plastic material may be made from a tubular blank (10) having an outer diameter which is slightly smaller than the desired outer diameter of the finished tubular body. The blank, which is made by winding a plurality of layers of fiber reinforced, unhardened plastic material around a mandrel, is arranged in a mould (24) having an inner peripheral mould surface (23) with a diameter and smoothness corresponding to the desired diameter and smoothness of the outer surface of the tubular body to be made. The outer peripheral surface (25) of the blank (10) is subsequently pressed into contact with the inner mould surface (23) by providing a substantial pressure difference between the inner space of the blank and the space defined between the outer peripheral surface (25) of the sample (10) and the mould surface (23), and the plastic material of the blank (10) may at the same time be heated, if desired, for example in an autoclave. The plastic material is hardened or set while the outer peripheral surface of the blank is maintained in contact with the mould surface. If the plastic material is of the thermo-setting type, such setting or hardening may be caused by heating the plastic material in the autoclave.
