Abstract
A method of manufacturing a composite sandwich structure, the method comprising a preform assembly method. The method comprises providing a preform () comprising at least two sheets () connected by a plurality of extensible threads (), and affixing to the outer face of each sheet (), a face sheet (). The adhesion is by a film adhesive () placed over the respective sheets (), and the preform () is subjected to pressure or heat to set the film adhesive (). The method further comprises a method of molding a composite sandwich structure, the method comprising placing a preform () in a mold (), creating pressure differentials between respective chambers () within the mold (), feeding a resinous compound into the mold (), and allowing the resinous compound to set and cure. The invention also provides composite sandwich structures made in accordance with the methods.
