Today, bio-composites—made of raw materials of biological origin—are giving engineers new insight on how to improve the environmental performance of future aircraft. It may be hard to believe, but five decades ago, up to 70% of an aircraft was made of a single material: aluminium.
21 lut 2022 · In order to develop a lightweight composite aircraft structure, the Boeing engineers determined the optimum composite material for particular applications around the airframe by conducting the design process without preconceived ideas.
Composite materials have emerged as the materials of choice for increasing the performance and reducing the weight and cost of military aircraft, general aviation aircraft, transport aircraft and space launch vehicles, Figure 1 (Application of Composites on Flight Vehicles).
In the late 1980s and 1990s, composites were used for the primary structures of large civil aircraft. Two reasons for this were improvements to carbon fibers and improved toughness of epoxies. The Boeing 777, introduced in 1995, utilizes composite materials for primary structures (empennage and floor beams).
21 lut 2022 · In the aircraft structure, composites such as polymer matrix composite (PMC), metal matrix composite (MMC), and ceramic matrix composite (CMC) were used. Composite materials were used to construct nearly half of the aircraft’s construction.
21 lut 2022 · Composite advanced materials, which are typically continuous for aerospace use, carbon fibers with a rubber matrix, will provide superior material characteristics than metals, therefore, in order to attain lighter structural structures.
8 cze 2016 · Composite materials are particularly attractive to aviation and aerospace applications because of their exceptional strength- and stiffness-to-density ratios and superior physical properties.
