OVERVIEW

Safe composite structure is an important part of the development of modern flight vehicles. It involves many disciplines, like Material science, Structural engineering, Manufacturing technology, Maintenance engineering, Inspection technology and Operation on the ground and in the air. Structural safety is a necessary requirement in the achievement of successful innovation and efficient design development.

The event "Safe composite structure," S, is a joint event made up of at least these four sub events:

where

• D is the event "Safe structural design";

• I is the event "Safe maintenance," which includes proper inspection and repair methods;

• M is the event "Safe manufacturing," which includes performing according to specifications, drawings and instructions;

• O is the event "Safe operation," which includes abiding by operating procedures and flight manuals; e.g. not exceeding limit external loads.

The probability of safe structure can be expressed as:

according to the multiplication rule in the probability theory.

The first factor, P( D I M O) is the probability of a safe design, given safe maintenance, safe manufacturing and safe operation;

The second factor, P( I M O) is the probability of safe maintenance, given safe manufacturing and safe operation;

The third factor, P( M O) is the probability of safe manufacturing, given safe operation; and

The fourth factor, P( O) is the probability of safe operation.

This book will primarily focus on the first factor, referring to "safe composite structural design." Structural integrity...
