RESEARCH IN FABRICATION TECHNIQUES FOR FIBER GLASS REINFORCED PRIMARY AIRCRAFT STRUCTURES

Abstract

The report covers the design, fabrication, and testing of glass reinforced plastic (GRP) 1/2 scale models of a main torsion box assembly incorporating an NACA 642-215 airfoil. The structure was designed as a sandwich wall box beam, with nonwoven oriented (NWO) GRP faces and a GRP honeycomb core. Fabrication techniques for filament winding a double tapered box beam were investigated and a technique was developed which made it possible to filament wind the 45 degrees fibers as well as the hoop and axial oriented fibers. Unidirectional tape, 12 inches wide, made from E-HTS glass filaments and 20 end roving with both E-HTS and S-HTS glass filaments, preimpregnated with an epoxy resin system were utilized in the fabrication of the facings. Both the hand layup and filament winding techniques of fabricating primary aircraft structures were found to be practical and within the current state of the art.
