Device and method for processing a fibre compound structure

摘要

The present invention provides a connecting device for connecting an unhardened fiber layer which is arranged on a surface section of a fiber compound structure to the fiber compound structure. The connecting device comprises pressure cushion comprising a pressure cap for being arranged above the surface section and a pressure tight cap mat which is pressure tightly connected to a circumferential border of the pressure cap, thereby forming a pressure area which is limited by the pressure cap and by the cap mat. The connecting device further comprises a pressure inducing means for inducing an overpressure which presses the cap mat against the fiber layer into the pressure area. According to a further aspect the invention provides a processing method for processing a fiber compound structure. In a first step at least one unhardened fiber layer is arranged on a surface section of the fiber compound structure.

主权项

1. A connecting device for connecting an unhardened fibre layer arranged on a surface section of a fibre compound structure to the fibre compound structure, the connecting device comprising:
a pressure cushion of said fibre compound structure, the pressure cushion comprising:
a pressure cap;a semi-rigid pressure-tight cap mat configured to form a low pressure area with the surface section of said fiber compound structure; a pressure area limited by the pressure cap and by said pressure-tight cap mat; a low pressure area limited by said pressure-tight cap mat and the surface section of said fibre compound structure; wherein the pressure cushion is capable of providing an effective hardening pressure of at least 1 bar against the unhardened fiber layer; a pressure inducing means capable of inducing an overpressure into the pressure area, an evacuation means configured to evacuate air from said low pressure area; and a press-on assembly comprising a support counter bearing on a side of said fibre compound structure opposed to the surface section, capable of forming a hermetically sealed area between the pressure cushion and the surface section of said fibre compound structure; wherein said semi-rigid pressure-tight cap mat is provided such to fill out contours and/or step like sections of the fibre compound structure by preparing an accordant inversely contoured pressure-tight cap mat.
