Abstract

Composite material, microporous skin, partic. for making sandwich construction parcels, is produced by: (a) laying a skin (16) of fine mesh fabric coated with resin over a mould release agent covered metal tooling (15); (b) putting in place necessary surrounding consumable prods.; (c) putting the skin, tooling and consumables into a flexible bag (18) connected to a vacuum source; (d) applying vacuum to flatten the skin against the tooling; and (e) placing the bag and its contents into an oven, curing the resin then demoulding the microporous skin.
