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 backsheet that sandwich between them first and second open cell core panels thatarespliced together along intermeshing edges of the panels with projections fromthepanels engaging into slots into the panels. There is no adhesive substanceemployedbetween the intermeshing edges of the two core panels. The joining andsplicing of theintermeshing core panel edges retains the structural and acoustic capabilityof thecomposite without the need for adhesives (film, foaming, paste, pottingcompound, etc.)between the intermeshing edges of the core panels.
