Abstract: A method for producing an article of composite material comprising the steps of: providing a moulding tool of male type; placing one or several prepregs on the moulding tool, forming a fibre stack; placing a dry layer, e.g. fabric, externally on the fibre stack, forming a fibre stack having a dry surface; providing a moulding tool of female type; overturning or tilting the stack having a dry surface from the male tool to the female tool. The method may further comprise the step of arranging said dry fibre layer so that this comprises the edge of the fibre stack. The dry layer may be made of a metal net or other suitable metal structures, or be made of glass fibre fabric or another similar glass fibre structure, or a combination of glass fibre and metal. The fact that metal is an electrically conducting material and that glass fibre is an electrical isolator may be exploited, particularly when producing aircraft components.

Abstract: This invention concerns a method for fabricating a curved beam from fiber composite material. A flat fiber composite laminate (2) comprising a plurality of layers and at least two different fiber directions is formed. The fiber composite laminate (2) is disposed in contact with a male tool (1) comprised of a first flange (1a), a second flange (1c) and an intermediate web (1b), which male tool (1) is curved in its longitudinal direction with a radius of curvature R in such a way that the first flange (1a) has a shorter longitudinal extent than the second flange (1c). The fiber composite laminate (2) is brought into contact with and secured to the first flange (1a) of the male tool (1). The male tool (1) and the fiber composite laminate (2) are then rotated relative to one another so that the fiber composite laminate (2) is brought into contact with the intermediate web (1b) of the male tool (1) in a first rotational movement, and brought into contact with the second flange (1c) of the male tool (1) in a second rotational movement. The fiber composite laminate (2) hardens on the male tool (1), and the finished beam is separated from the tool (1). The invention also relates to a beam of fiber composite material fabricated according to the method.

Abstract: In a method for filling pores between two adjacent layers of a laminate for a component with high demands upon strength and comprising several layers of fibre composite having within each layer substantially parallel fibres embedded in a matrix, a connection path is created, through which a medium may move inside the laminate, between the exterior of the laminate and the pore by exerting the laminate at least in the region of the pore for forces making slots to propagate substantially in the matrix through each laminate layer along the fibre direction of the layer. A flowing, curable material is after that applied at an outer surface of the laminate and this is brought to fill the pore through the connection path. Finally, the material filling the pore is brought to cure.

Abstract: The present invention relates to methods for forming composite structures and composite structures formed by these methods. The methods include arranging a stack of prepreg sheets on a mold. The composite material is substantially sealed within a vacuum bag. One or more vacuum ports extend through the vacuum bag. Vacuum is applied through the vacuum ports for drawing air from the stack of prepreg sheets. Air in the space between adjacent prepreg sheets in the stack is evacuated through at least one less-impregnated layer within a least one of the two adjacent prepreg sheets. The less impregnated layer communicates with the vaccum port. The process may be repeated until the stack comprises a predetermined number of prepreg sheets. The composite material is cured and the structure is released from the mold and the vacuum bag, thus providing a composite structure formed from evacuated, cured stack of prepreg sheets.
