Described are a hybrid yarn consisting of two groups of filaments, one group consisting of one or more varieties of reinforeing filaments (filaments (A)) and the other group consisting of one or more varieties of matrix filaments (filaments (B)), wherein - the filaments (A) of the first group have an initial modulus of Above 600 cN/tex, preferably of 800 to 25,000 cN/tex, in particular of 2,000 to 20,000 cN/tex, a tenacity of above 60 cN/tex, preferably of 80 to 220 cN/tex, in particular of 100 to 200 cN/tex, and a breaking extension of 0.01 to 20%, preferably of 0.1 to 7.0%, in particular of 1.0 to 5.0%, - the filaments (B) of the second group are thermo- plastic filaments which have a melting point which is at least 10°C, preferably 20 to 100°C, in par- ticular 30 to 70°C, below the melting point of the filaments (A), - the filaments (A) have a crimp of 5 to 60%, prefer- ably of 12 to 50%, in particular of 18 to 36%, a three-dimensionally deformable sheet material pro- duced from this hybrid yarn, and a fiber reinforced shaped article produced from the deformable sheet material. Also described are processes for producing the articles mentioned.
