Why might an aircraft's structure limit fabric choice?

An aircraft's structure limits fabric choice primarily because the fabric must be compatible with the structural requirements related to weight, strength, and the way stress is distributed over the surfaces of the aircraft. Each aircraft structure has specific design parameters that must be adhered to in order to ensure safety, performance, and durability.

The choice of fabric directly affects how the aircraft will handle aerodynamic loads and stresses during flight. For example, if the fabric is too heavy, it could negatively impact the aircraft's performance; conversely, if it is not strong enough, it could lead to structural failure. Additionally, the stress distribution is a crucial factor because different areas of the aircraft may experience varying degrees of stress during operation. Thus, selecting a fabric that meets the necessary specifications in terms of tensile strength and weight will ensure that the aircraft remains safe and effective under normal flight conditions.

Other options may suggest aesthetic or pricing considerations, but these are secondary to the fundamental mechanical requirements that an aircraft's structure imposes on the fabric choice.
