Abstract:
1. Method for fixating a fiber preform comprising the steps of: molding a dry semi-finished fiber material containing carbon fibers or consisting thereof into a fiber preform of a predetermined shape; one of subsequently applying a binder to the fiber preform and bonding the binder substance with the fiber preform or applying a binder to the semi-finished fiber material and bonding the binder substance with the semi-finished fiber material prior to molding the fiber preform, wherein at least one of a mass of the binder substance amounts to more than 2 and up to 5 percent of a mass of the semi-finished fiber material or of the fiber preform; activating the binder substance by increasing a temperature of the fiber preform and the binder substance wherein an electrical current is conducted through at least one part of the carbon fibers to increase the temperature of the fiber preform; and subsequently saturating the fiber preform with a matrix, wherein the quantity of the matrix amounts to 25 to 85 percent by volume of the finished fiber preform.
