摘要： A material specimen is provided. The material specimen for tensile or HCF tests includes two welds arranged opposite one another on the specimen which do not touch. The welds are arranged symmetrically in relation to a plane or mirror symmetrically in relation to a longitudinal axis of the specimen which extends parallel to the line of effective force.

摘要： A blade for a turbine or a compressor, at least partially made of fiber-reinforced plastic, in particular carbon fiber reinforced plastic, being particularly durable under operating conditions is provided. The blade includes a blade body and a blade root. The blade body is substantially made of a folded fabric web made of fiber reinforced plastic, wherein a retaining loop is formed in the area of the fold, and wherein a blade surface is formed in the area of the fold, and wherein a blade surface is formed from the overlapping web ends. The blade root includes a longitudinal beam and at least two holders for anchoring the blade in a corresponding groove of a rotor, the holders being preferably each fixedly connected to the beam at both ends. The blade body is suspended on the beam by means of the retaining loop.
