Mechanical properties, micro structure and crack propagation behaviour of different fabric reinforced mono and hybrid composites for materials of wind turbines have been investigated. Mechanical properties of different fabrics (glass, basalt and carbon) reinforced mono and hybrid composites with epoxy resin matrix have been compared. For characterization of materials tensile, three-point bending and single-edge notched tensile (SEN-T) tests with acoustic emission study were used and scanning electron microscope (SEM) pictures have been taken of the fracture surfaces of composite specimens. Similar behaviour of glass and basalt fibre reinforced composites was revealed by tensile and three-point bending tests. The satisfactory adhesion between fibre and matrix was shown by scanning electron microscope. The fibre-break was proven by the taken pictures to be the main failure mechanism. Results of mechanical tests were also confirmed by acoustic emission study. The crack propagation method of glass and basalt fabric reinforced composites is similar.

This paper focuses on the analysis of the deformation behaviour with respect to the acoustic emission response and mechanical properties of differently extruded magnesium Mg-Mn alloys. Six types of Mg-Mn alloys (with Al, Ca, Ce, Y, Nd additions) were processed by indirect extrusion with two different speeds. Alloys with addition of Ca, Al and Nd were selected and presented in this manuscript due to their prospective mechanical properties. Additions of Ca and Al had significant influence on the microstructure refinement and texture of the Mg-Mn alloy, whereas addition of Nd led to the absence of the tension-compression asymmetry. Measurements of the acoustic emission were done during the uniaxial tension and compression tests. The results are discussed with respect to the influence of alloying elements on the deformation behaviour in terms of the activation of dislocation glide and twinning.
