发明名称 Fan blade reinforcement using bonded hollow spheres
摘要 This invention is a process by which fan blades or any shape needing a lightweight reinforcement are strengthened using hollow spheres, bonded together with an adhesive material used as a matrix. This combination of hollow spheres and adhesive matrix forms a lightweight construction that exhibits extremely high compressive strength. Thermoplastic or thermosetting resins may be used for a matrix material. A plurality of hollow spheres, all being the same size, are inserted into the area to be reinforced. The spheres being round in shape and light in weight, flow easily with fluidic properties, although slight agitation will ensure complete distribution, settling, and contact of each hollow sphere to the next in an organized, virtually symmetrical fashion. The matrix material is then inserted into the interstices surrounding the hollow spheres, forming a bond between each hollow sphere, and mechanically joining them; thus forming a bonded, lightweight reinforced fan blade.
