ABSTRACT:
A method of constructing fibrous composite material, and a resulting structure, having a modular construction in which the modules are formed on mandrel assemblies having a metal core and an elastomeric, deformable and removable sheath. Fibrous composite material is wrapped around each sheath, which in a complex shape such as a thrust reversing cascade for a jet engine, has sets of similar modules arranged in rows across layered composite ribs and in columns in which the modules are mutually engaged. When bonded by heat and pressure, the epoxy matrix of the composite material joins the ribs and the modules into a structure of high strength. In a cascade configuration a slotted medal plate is bonded to the ribs and the modules, being positioned in slots in the plate, with modules positioned fore and aft of the plate to increase the bonding area.
