Abstract
An improved resin for use in making honeycomb sandwich panels. The improvement involves modifying a phenolic resin so that the amount of smoke and heat generated during combustion is reduced. The reduction in smoke and heat generation is achieved by reducing the amount of phenol used to form the phenolic resin. The phenol is replaced by low-smoke producing sulfone compounds such as 4,4'-bisphenol-S, 3,3'-bisphenol-S, biphenol and bisphenol ethers which reduce the number of smoke producing methylene or methylene ether linkages present in the cured phenolic resin. The low-smoke producing resin may be used as a dip resin for coating the honeycomb or as the matrix resin for the core and face sheets of the sandwich panel.
