" WINGS OF GLASS " USE OF GLASS & FIBERGLASS IN BOEING 747 JET AIRPLANE DESIGN & CONSTRUCTION 75182

This educational film by Boeing Aircraft, "Wings of Glass", shows how the company uses innovative techniques to use glass, fiberglass and other glass and plastic composite materials to produce lighter, stronger aircraft components. The Boeing 727 and 747 aircraft are shown, as well as the assembly lines in which highly skilled workers painstakingly create many of the aircraft components by hand and using precision machinery. The film outlines the advanced use of glass and fiberglass materials in modern manufacturing, particularly in the aviation industry. It highlights how ancient glassworking skills have evolved into the production of modern materials like fiberglass and plastics, which are crucial in making lighter, stronger, and more efficient aircraft. The production process for creating fiberglass components, such as those used in the 747 superjet, involves several detailed steps, including the preparation of honeycomb cores, layering fiberglass fabric, and curing the parts under heat and pressure. Throughout the process, skilled craftsmanship plays a critical role in ensuring quality, with the end result being parts that are lighter, more durable, and up to 70% lighter than aluminum. These innovations have revolutionized aircraft design, allowing for greater efficiency and safety. 00:00 The narrator introduces the idea that glassworking skills, both ancient and modern, have been central to human craftsmanship, influencing various fields like art, science, functional design, and mass production. 1:01-2:43 The focus shifts to the aviation industry, specifically the production of aircraft. New materials, including fiberglass and plastics, have been combined to create lighter and stronger aircraft structures. The 747, a new superjet, uses fiberglass reinforced plastics for key control surfaces like rudders, elevators, and flaps. 2:53-5:01 The process of producing fiberglass parts for aircraft begins with shaping materials like honeycomb cores. These cores are carefully sawed, spliced, and trimmed to the required size. The cores are then potted with metallized plastic for added strength. 5:08-6:00 Further steps in core preparation include masking, curing, and beveling edges. Caution is required to avoid stretching the honeycomb, which could damage the structure. After beveling, the core is stored until it’s needed for assembly. 6:08-7:03 Fiberglass fabric (pre-preg) is carefully trimmed and handled, as it has a limited lifespan and must be stored under refrigeration. This fabric is used in layers for the assembly of the aircraft parts. 7:10-8:22 The fiberglass layers are laid out on molds with precise attention to detail, ensuring that the layers are properly aligned for stress resistance. Wrinkles and overlaps are carefully worked out by hand, and special care is taken to make sure parts fit together correctly. 8:31-10:09 The fabrication process continues with the application of the pre-preg fabric and the precise placement of honeycomb cores, followed by vacuum sealing and curing. The parts undergo curing in an autoclave under heat and pressure, transforming into lightweight, durable structures. 10:22-11:53 After curing, the parts are trimmed, drilled, and finished. If necessary, the parts are painted. The whole process relies on detailed instructions and the skill of workers to ensure high-quality results. 12:01-13:02 Fiberglass parts are cheaper, lighter, and more durable than aluminum. They are also flexible, allowing features like the 747’s adjustable leading edge flap. The manufacturing process highlights the importance of skilled craftsmanship in creating advanced aviation technologies. 13:04-13:36 The film concludes by emphasizing the role of hand workmanship and pride in producing high-quality, durable, and efficient aircraft parts.
