Abstract

UNDER PHASE I ABARIS CONDUCTED A CONCEPTUAL AND PRELIMINARY DESIGN STUDY OF THE APPLICATION OF ADVANCED COMPOSITES TO THE ASROC LAUNCHER MK 112 FOR WEIGHT REDUCTION AND CORROSION RESISTANCE. THE MAJOR COMPONENT ANALYZED WAS THE GUIDE, SPECIFICALLY THE ALUMINUM HONEYCOMB PANELS. THREE ALTERNATIVE CONCEPTS WERE DEVELOPED AND ANALYZED, WHICH ESTABLISHED THE FEASIBILITY OF REPLACING THE ALUMINUM HONEYCOMB PANELS WITH ONES FABRICATE OF CORROSION RESISTANT ADVANCED COMPOSITES. THE ANALYSIS INDICATES THAT THE DESIGNS PROVIDE ADEQUATE STRENGTH, STIFFNESS, REDUCED WEIGHT, AND IMPROVED CORROSION RESISTANCE. A STRUCTURAL CONCEPT OF A CUSTOM CORE USING HYBRID MATERIALS (PREPREG FIBERGLASS AND GRAPHITE) WAS SELECTED AS THE MOST COST EFFECTIVE. UNDER PHASE II, ABARIS PROPOSES TO CONDUCT DETAIL DESIGN AND ANALYSIS FOLLOWED BY FABRICATION OF ADVANCED COMPOSITE PANELS. SELECTED CRITICAL COMPONENTS AND A REPRESENTATIVE PANEL WOULD BE STRUCTURALLY TESTED. A COMPLETE SET OF PANELS WOULD THEN BE FABRICATED, AND ASSEMBLED AT NOD LOUISVILLE, KY TO ASSURE THAT THE DESIGN WAS COMPATIBLE WITH EXISTING OVER HAUL PROCEDURES. A DETAILED TEST PLAN FOR FOLLOWON STRUCTURAL AND OPERATIONAL TESTS WOULD BE PREPARED IN CONJUNCTION WITH NUSC, NEWPORT, RI.
