Abstract

1,147,775. Stressed skin members. J. L. HILLS. 2 Aug., 1966 [16 Aug., 1965], No. 34655/66. Heading B5A. [Also in Division E1] A structural or load-bearing member, e.g. a window-frame, is produced by moulding a dimensionally stable core (e.g. comprised of a mineral filler with a polyester resin binder), and applying to said core a skin of fibre-reinforced plastics (e.g. glass fibre-reinforced polyester resin) which has a degree of shrinkage of at least 3% by volume on setting (preferably about 7%), thereby becoming stressed. The fibre may be in the form of a fabric having directional fibre orientation. The binder used for the core may also have a degree of shrinkage of at least 3% on setting (e.g. about 7%) and the filler may be of a type which promotes such shrinkage.
