Abstract

1531481 Curing fibre-reinforced resin laminates HAWKER SIDDELEY AVIATION Ltd 2 Jan 1976 [2 Jan 1975] 117/75 Addition to 1441919 Heading B5N In carrying out the process of claim 2 of the Parent Specification, two preliminary stages are carried out at a temperature at which slow, but not rapid, gelation will occur, the total time occupied by these stages and the time occupied by the post stage being respectively more and less than that for slow gelation to occur, substantially equal negative pressures being maintained inside and outside the envelope or membrane during the first stage, and the pressures being brought to those of the cure cycle during the second stage.
