发明名称 Metallising thermosetting plastics contg. reinforcing fibres - after preliminary etching with chromosulphuric acid
摘要 <p>Process for metallising thermosetting plastics is by preliminary etching in oxidising acids; activating; sensitising in a Pd chloride soln.; dipping in an accelerator soln.; electroless Ni-plating in a quick-plating Ni bath; Cu electroplating and metallising. In the addition, fibre-reinforced thermosetting plastics are pre-etched for 0.5-20 min., at 50-80 degrees C, in a chromosulphuric acid soln. Uses include satellite components, eg.g. resonators for aerial-combining filters. Adhesion of metal layers on fibre-reinforced materials is a superior to adhesion achieved on thermosetting plastics contg. no fibre strengtheners. Metal layer cannot be peeled off substrate by cutting or filing. In example, pre-etched materials are C fibre-reinforced epoxy resin parts and glass fibre-reinforced unsatd. polyester parts.</p>
