SANDWICH-STRUCTURAL COMPOSITE APPARATUS WITH CORE JOINING AND SPLICING METHOD FOR RETENTION OF STRUCTURAL AND ACOUSTIC CAPABILITY

摘要

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.
