Abstract
The invention relates to a rib foot having a blade formed by first and second blade parts that are connected by a bite. The rib foot has a first base part that is connected to the first blade part by a first corner and a second base part that is connected to the second blade part by a second corner. The rib foot also has a first flange that is connected to and extends away from the first base part and a second flange that is connected to and extends away from the second base part. The blade and base parts are formed from a composite material that includes reinforcement fibers embedded in a matrix. At least some of the reinforcement fibers run continuously from the first base part into the second base part via the first corner, the blade and the second corner.
