Abstract

The present invention relates to a method of forming a curved prepreg strip or sheet, especially for use in fabricating a composite component. The method comprises: providing a strip or sheet of prepreg material having reinforcing fibres; and drawing or conveying the strip or sheet of prepreg material in a travel direction, wherein the strip or sheet is drawn or conveyed in the travel direction at a speed which differs across a width of the strip or sheet transverse to the travel direction. Similarly, the invention relates to an apparatus (1) for forming a curved prepreg strip or sheet (S), having: a mechanism (2) for drawing or conveying a strip or sheet (S) of prepreg material in a travel direction (T), wherein the mechanism (2) is configured to draw or convey the strip or sheet (S) of prepreg material in the travel direction (T) at a speed which differs across a width (w) of the strip or sheet (S) transverse to the travel direction (T)
