Patent DE-4034915-A1 (DE)
IPC: B29C67/20
Filed: 1990-11-04
Abstract: The subject of the invention is a method for manufacture of sandwich-type moulded articles and panels, mainly of textile fibre structures, which contain fibres having different thermal properties, by pressure, heat and moist hot air, using moulds, which have a greatest-possible, uniform porosity, to press panels and moulded articles with a sandwich structure and cool them in the same cycle, the moist hot air and a special design of the mould causing a positive pressure to be achieved in the mould and consequently in the fibre structure, which pressure makes the outer sides in particular of the fibre mats set largely evenly on the mould surfaces, the inner structure of the moulded articles or panels then having a lower density. By using this method, the weights of moulded articles and panels to be described can be reduced, which is of decisive significance in terms of price and acceptance on the market for energy reasons alone. Furthermore, by using fibre systems comprising the same polymer, reuse is largely possible, since then it is possible to dispense with binder systems of a different type.
