Environmental Degradation of Composite Materials
ARP6287
In accordance with § 4.11 of AS36100, materials used in the construction of pallets, nets, and containers shall take into account the effects of environmental conditions, such as temperature, humidity, and UV degradation, expected in service.
In accordance with (E)TSO-C90, the applicant shall consider environmental degradation due to aging, ultra-violet (UV) exposure, weathering, etc., for any materials used in the construction of pallets, nets, and containers.
The purpose of this Aerospace Recommended Practice (ARP) is to provide guidelines for the basic requirements to be considered regarding environmental degradation effects when qualifying composite materials in the design to fulfill the (E)TSO-C90 Minimum Performance Standard.
Material qualification is the verifying of a materials attributes and characterizations, which are typically determined through testing.
Material variances related to raw materials and manufacturing processes are not part of this Aerospace Recommended Practice (ARP), nor is damage tolerance. However, these variances cannot be neglected, as all variances shall be considered when deciding the test factors for environmental effects.
Rationale:
This Aerospace Recommended Practice (ARP) specifies the basic requirements and principles to be used during the material qualification process of composite materials used in ULDs, considering the effects of environmental degradation.
