Generic Basis Values and Acceptance Criteria for Composite Materials

摘要

The approaches used to compute engineering design values (A-basis and B-basis) and acceptance sampling criteria were developed independently in the twentieth century. This was a practical approach for that time period but it isn’t working well for new materials with process dependent strength and modulus characteristics, such as carbon fiber composite materials. This paper lays out an approach designed to meet industry needs for identification of engineering design values applicable to the majority of manufacturing facilities using approved processing procedures for carbon-fiber composite materials along with corresponding acceptance criteria set to specific values for both the consumer’s and the producer’s risks.
