Abstract

920,042. Moulding cellular resin articles. DUROPLAST SCHAUMVERBUNDBAU G.m.b.H. April 6, 1961 [April 6, 1960], No. 12444/61. Class 87(2). In a process for producing lightweight articles such as constructional parts for prefabricated buildings, low density cores 5, 6, which may be of foamed synthetic resin, or pressed straw or hemp sealed against taking up resin, are placed in a mould (not shown) and sheathed with glass fibre fabric which fills the spaces in the mould. The mould is closed and hardenable casting resin, such as unsaturated polyester resin, is forced under pressure into the mould and hardened to form an outer wall 1, an inner partition 2, ribs 3 and bridge pieces 4 reinforced with glass fibre. For some purposes only one core may be used.
