Abstract: A sandwich-structural composite is assembled from a front sheet and a back sheet that sandwich between them first and second open cell core panels that are spliced together along intermeshing edges of the panels with projections from the panels engaging into slots into the panels. There is no adhesive substance employed between the intermeshing edges of the two core panels. The joining and splicing of the intermeshing core panel edges retains the structural and acoustic capability of the composite without the need for adhesives (film, foaming, paste, potting compound, etc.) between the intermeshing edges of the core panels.

Abstract: The present application is directed to methods of preparing a wet composite patch for use in various applications, such as, for example, reworking a composite part of an aircraft. The method comprises heating the composite patch to a temperature that causes resin containing gaseous components to flow from the patch through a flow path. The gaseous components are vented from the resin while restricting the flow of resin from the composite patch by restricting the flow of resin through the flow path. Systems for performing the methods of the present application are also disclosed.
