FAA AC 20-107B Composite Material Structural Testing
The Federal Aviation Administration (FAA) Advisory Circular AC 20-107B provides comprehensive guidelines for the testing of composite materials in aerospace structures. This standard is crucial for ensuring that aircraft components meet stringent safety and performance requirements, particularly where composite materials are used. Composites have become increasingly favored due to their lightweight properties, which contribute significantly to fuel efficiency and reduced emissions—a critical aspect as the aviation industry aims to adhere to environmental regulations.
The testing outlined in AC 20-107B involves several stages that ensure structural integrity and compliance with standards set by the FAA. The first step is the preparation of specimens, which must be representative of actual components used in aircraft structures. This includes selecting appropriate test coupons or parts based on design specifications. Specimen preparation requires meticulous attention to detail; any deviation could compromise the accuracy of the results.
After preparing the specimens, the next phase involves subjecting them to various mechanical tests designed to simulate real-world conditions under which they will operate in-service. These tests can include but are not limited to tensile strength, compressive strength, shear modulus, flexural properties, and impact resistance assessments. The equipment used for these evaluations includes universal testing machines (UTMs), digital load cells, extensometers, and ultrasonic thickness gauges among others.
Once the tests have been conducted, it is essential to interpret the data accurately against specified acceptance criteria outlined in AC 20-107B. Compliance with these standards ensures that manufacturers can demonstrate adherence to quality control measures during production processes. It also helps regulators verify whether new designs meet safety thresholds before being approved for use on commercial aircraft.
Aerospace composites present unique challenges compared to traditional metallic materials because their anisotropic nature means properties vary depending on orientation and direction of load application. Therefore, careful consideration must be given when selecting test methods that accurately reflect expected operational stresses experienced by parts during flight operations.
Incorporating advanced technologies such as finite element analysis (FEA) into the testing procedure allows engineers to predict potential weaknesses within composite structures more effectively than relying solely on empirical data obtained from physical tests alone. By integrating FEA results with experimental findings, manufacturers gain valuable insights into how best to design safer and more reliable aircraft systems.
The importance of this type of testing cannot be overstated given the critical role played by composite materials in modern aviation technology. Ensuring strict adherence to AC 20-107B helps maintain public confidence in air travel safety while driving innovation towards greener, more efficient flying practices.
Applied Standards
The FAA's Advisory Circular AC 20-107B is based on international standards like ISO 5289, ASTM D3415, and EN 12663. These guidelines provide a robust framework for evaluating composite materials used in aircraft structures. Specifically, ISO 5289 details methods for tensile testing of plastics, which are often components within composite assemblies. ASTM D3415 focuses on the determination of flexural properties of plastics, another key characteristic evaluated during this kind of structural evaluation.
EN 12663 covers impact resistance tests for plastic materials and their composites, addressing one of the most challenging aspects when dealing with composite components subjected to sudden impacts. By adhering strictly to these standards, laboratories can ensure that their testing protocols are consistent with global best practices recognized by industry professionals.
The application of these internationally accepted norms guarantees accurate measurement techniques and reliable data interpretation processes. This consistency across borders facilitates better collaboration among manufacturers worldwide, promoting innovation while maintaining high safety standards throughout the supply chain.

Environmental and Sustainability Contributions
The use of composites in aerospace structures has numerous benefits beyond mere weight reduction; it also plays a significant role in fostering environmental sustainability. Lightweight materials like carbon fiber-reinforced polymers (CFRP) contribute to lower fuel consumption, reducing greenhouse gas emissions per passenger mile traveled significantly compared to heavier alternatives.
Moreover, recycling composite waste streams presents another opportunity for sustainable practices within the industry. Advances in material science have led to improved methods of recovering valuable resources from scrapped parts, thereby minimizing landfill contributions and promoting circular economy principles.
The aerospace sector faces growing pressure to reduce its carbon footprint as part of broader efforts towards climate change mitigation strategies.
