Abstract

Rigid bodies are formed by thinly coating individual particles of finely powdered material with a thermosetting resin, compacting the material to form a porous body, partially curing the resin at room temperature and then completing the curing in stages at progressively elevated temperatures. The pores of the body thus formed may be partially or completely filled with a metal e.g. nickel by chemical nickel plating or by an atmosphere of nickel carbonyl. In one example a porous body of finely divided steel, prepared as above, was sensitized by a three minute dip in a bath containing 400 cc of hydroquinone, 100 cc of Pyrocatechol and 1000 cc of acetone and then activated by a two minute bath of 10 gms of stannous chloride 40 cc hydrochloric acid, and 1000 cc distilled water. The thus treated body was then placed in a chemical nickel plating bath composed of nickel sulphate (0.08 moles/litre), sodium hypophosphite (0.23 moles/litre), lactic acid (0.3 moles/litre) and propionic acid (0.003 moles/litre) for 16 hours after which the pores were completely filled. In a second example a porous body of glass was treated as above and then chemically plated with nickel for 20 minutes at 190 DEG F in a bath of 7 ozs of nickel chloride, 1 1/2 ozs sodium hypophosphite, 1 1/2 ozs sodium litrate and 1 gallon of water. This was insufficient to completely fill the pores and this process resulted in a porous body.ALSO:Rigid structures are formed by applying a very thin film of a thermosetting resin to the surface of finely-divided individual glass particles, compacting the particles to form a porous preform, partially using the resin at room temperature and finally completely curing the resin in stages at progressively elevated temperatures. The pores of the body thus formed may be filled with a second thermosetting resin, or may be completely or partially filled with metal (nickel) by a chemical plating process or by an atmosphere of e.g. nickel carbonyl. In one embodiment a porous mould is made by coating the particles with a thermosetting resin dissolved in a solvent, evaporating the solvent, and manually applying the coated particles to a shaping pattern or mould. The whole is then enclosed in a flexible impervious bag and further consolidated after which the bag is removed and the resin pre-cured and then cured in stages as stated above. The mould is preferably composed of strata of powdered material having different sizes the finest being at the operative surface of the mould whilst the coarser particles comprise the body of the mould (see Fig. 5, not shown).ALSO:Individual particles of finely divided powdered material are coated with a thermosetting resin by placing the particles in a cloth bag or the like, immersing the bag in a vessel of resin, which contains a solvent, and ultrasonically vibrating the vessel. The resin solution is then allowed to drain off the coated particles after which the solvent in the coating is evaporated.
