Abstract

The stiffening mat or cellular structure is wrapped around the core, and this assembly introduced into the mould, so that the cellular surround completely fills the space to the mould walls, then the thermosetting resin is introduced and polymerised. Pref., the mould and its contents are maintained at the appropriate polymsn. temp. Before the core and the surrounding cellular or stiffening mat is introduced, a surface non-woven fabric may be placed inside the mould.
