Experimental study of mechanically stressed composite materials
Original language description
The phenomenon of stochastic electromagnetic emission (EME) from solids is based on the generation of an electromagnetic field accompanying the mechanical excitation of the solids in question. This phenomenon is generally termed fractoemission. Our experiments were carried out on a composite dielectric material, consisting of fibrous glass reinforcement which was bound with resin-based binding agents. Our model assumes that the crack walls get charged with electric charges +q(t) and q(t) in consequenceof the bonding electron statistical distribution during the crack forming process. The crack walls are moving with a velocity v(t). Both mentioned quantities can therefore be regarded as random processes. The time development of a voltage u(t) across a load resistor being connected in series with a sensing capacitor was measured. The time behaviour of the product of the electric charge and its velocity q(t).v(t) can be determined from the voltages u(t). The crack generation process may b
