ABSTRACT:
According to this invention, there is provided a reinforcement blanket having a plurality of layers of fiber-reinforcement materials sewn together. The sewing together of the various layers of the fiber-reinforcement materials provides a plurality of channels extending through the reinforcement blanket. The reinforcement blanket can be shaped into a preform or can be used directly as a reinforcement in a molding process. The channels in the reinforcement blanket aid in distributing a matrix resin during an impregnation process.
