چکیده انگلیسی
Short laser pulses have been used to generate elastic waves in continuous fiber reinforced aluminum or magnesium. With an optical interferometer the run-time of these waves in various directions of the samples can be measured contactless (point-source-point-receiver technique). From these data, the five independent components of the complete elasticity tensor for the unidirectional fiber reinforced composites can be determined. These results agree with measurements by a resonant beam technique, acoustic resonance and 4-point bending tests. The laser pulse technique has several advantages: it is contactless, non-destructive and it can be used for online quality control in production processes.
