APPLICATION OF NATURAL FIBERS IN AIRCRAFT INTERIORS AIMING FOR GREATER SUSTAINABILITY IN THE AERONAUTICAL SECTOR

Abstract

Sustainability has become a strategic guideline for the contemporary aeronautical industry due to the need to reduce environmental impacts associated with the manufacturing, operation, and disposal of aircraft components. In this context, the use of renewable and low-impact materials emerges as a promising alternative for aircraft interior development. This study analyzes the application potential of natural fibers especially pineapple, banana, and cactus fibers as substitutes for conventional leather used in executive aircraft seats and interior coverings. The research was developed through a qualitative and exploratory literature review, including a comparative analysis of mechanical, thermal, environmental, and regulatory properties. Results indicate that natural fibers present relevant advantages such as lower density, biodegradability, use of renewable resources, and lower energy demand during processing. However, limitations related to moisture absorption, structural variability, and compliance with flammability requirements established by FAR 25.853 and RBAC 25.853 were identified. It is concluded that these materials present potential for application in non-structural aircraft interior components, provided that flame-retardant treatments and hybrid composite developments are adopted to ensure technical compliance and operational safety.
