The guidelines and recommendations are meant to be a documentation of current knowledge and application of sound engineering principles to the development and implementation of composite material procurement and process specifications. This document can also be used to develop common industry specifications. This report is limited to recommendations and guidance on the development of material and process specifications. The guidelines and recommendations contained in this document should not be viewed as Federal Aviation Administration policy or as the only acceptable method for composite material specifications and qualification procedures. They are meant to be a documentation of current knowledge and application of sound engineering principles to the development and implementation of composite material procurement specifications specific to the liquid resins and continuous fiber reinforcements used in liquid molding processes. The goal of any material procurement document is to provide the necessary controls to ensure the material used to establish the qualification data and certification data has not changed beyond its normal variability. The goal of any process specification is to ensure that the process remains in control and produces material consistent with specified requirements
