Abstract
There is described a method for manufacturing a filament-wound hollow body. The method comprises providing a mandrel (2) rotatable about an axle (4); during rotation of the mandrel (2), winding filaments around an outer side of the mandrel (2) in combination with a hardening resin for providing a solid laminate (1) of the filaments after hardening of the resin. At least one hole is provided in the laminate by filament-winding a laminate (1A) onto the mandrel (2); then, before hardening of the first laminate (1A), providing a hole in the laminate by pushing filaments aside from a point location in first laminate (1A) to form the hole without breaking the filaments The laminate can be dimensioned for use as part of a vehicle or an aircraft.

A method for manufacturing a filament-wound hollow body, the method comprising:
- providing a mandrel rotatable about an axle;
- during rotation of the mandrel, winding filaments around an outer side of the mandrel in combination with a hardening resin for providing a solid laminate of the filaments after hardening of the resin;
- providing at least one hole in the laminate of the hollow body;
- filament winding a first laminate onto the mandrel;
- then, after the filament winding of the first laminate but before hardening of the first laminate, providing a hole in the laminate by pushing filaments aside from a point location in first laminate to form the hole without breaking the filaments.
