The invention relates to a method for recovering the glass fibres from composite materials in connection with recycling. This is of particular importance in connection with recycling of glass fibre blades from wind turbines and other fibre reinforced composite materials of the type where glass fibre is embedded in a matrix of polyester, epoxy or a similar polymeric substance or a thermoplastic material. The method of the invention consists in a thermal process in which the material is pyrolysed at a relatively low temperature in a closed furnace chamber with an inactive atmosphere, for example in the form of nitrogen. The temperature and combustion conditions are chosen such that the matrix is glasified while the glass fibres remain intact, thus making recycling possible. The by-product of the pyrolysis is combustible gas, which is carried off from the furnace. The energy in the gas may be utilised for a number of objects, such as: propellant for gas engines in combined heat and power plants or storage for later use. Alternatively, the gas may be burned with a minimum of environmentally damaging wastes, if combustion takes place in the temperature range of 1000-1200° C.

This invention is a new dynamo electric machine of the alternating current type which provides for the entire stator winding to operate as an alternating current induction machine for relatively shorter periods of very high torque output operation, then provides for a portion of the stator winding to operate as a direct current exciter field winding while the balance of the stator operates as the armature windings of a high efficiency salient pole alternating current synchronous machine. The said machine or any electrical machine is further made more compact for a specific rate of output by providing stator winding insulation of an insulating material which provides for very high temperature operation and/or relatively high volume circulation of coolant throughout the porous winding insulation and potentially operates successfully at much higher temperatures than typical insulation systems. Also provided is a novel means of rotatably supporting a rotor of a dynamo electrical machine.
