The Composite Materials Handbook
CMH-17 |
 |
Statistics Tutorial
|
The Composite Materials Handbook provides
world-class engineering information,
including databases, standards and guidelines for structural applications of
composite materials. Its
primary purpose is the standardization of engineering information for current
and emerging composite materials.
The Handbook therefore constitutes an overview of the field of composites
engineering and technology in an area which is advancing and changing rapidly.
In support of this objective, the handbook includes
methodology for performing a number of engineering processes associated with the
design, manufacture and continued operational safety of composite materials. These processes use rigorous
statistical data requirements to confirm acceptability. These statistical procedures are
sometimes intricate and confusing to individuals that are not familiar with
them.
In order to provide clarity to these procedures, a six (6) hour tutorial
session will be presented as part of the next CMH-17 meeting.
This tutorial is a comprehensive treatment of the CMH-17 methods for
statistical analysis and their importance to proper development of design
information. Students will
participate in an interactive session on the CMH-17 statistical methods,
including practical example problems.
Students need to bring a laptop computer with EXCEL
to participate in the interactive sessions as they will be focused on using the
specialized software available: Stat17, ASAP and HYTEQ.

Certification Tutorial
The Composite Materials Handbook provides world-class
engineering information, including databases, standards and guidelines for
structural applications of composite materials. Its primary purpose is the
standardization of engineering information for current and emerging composite
materials. The Handbook, therefore, constitutes an overview of the field of
composites engineering and technology in an area which is advancing and changing
rapidly.
A six-hour tutorial session will be presented as part of the
next CMH-17 meeting emphasizing Volume 3, Chapter 3. This chapter is being
developed to provide general information on the regulatory and technical issues
that need to be addressed when showing compliance with certification
requirements relating to composite aircraft structure. To achieve aviation
safety, certifying agencies require certification of design, production,
maintenance and operation at different stages in the aircraft program
development. Certifications of design and production are to ensure the initial
airworthiness of the aircraft. The compliance with maintenance requirements is
necessary to ensure the continued airworthiness of the aircraft.
The tutorial provides an overview of the subjects of
certification, regulations, design substantiation, and essentials of production
and maintenance delivered by subject experts, with an emphasis on structural
substantiation. The linkage among design, production, and maintenance functions
in the context of unique material properties of composite materials has long
been recognized as a critical part of safe and efficient certification.
Developing an awareness of regulations and their role is another essential
understanding for practitioners engaged in certifying aircraft.
The tutorial begins with general certification topics related
to product development, continued airworthiness, product modification, and the
need for a qualified workforce working in a team environment. This discussion is
followed by a summary of regulations associated with attaining production
approval, structural design and maintenance and repair. Two other segments of
the tutorial include production and maintenance, addressing important topics
such as production substantiation and implementation, quality control, and
defect disposition requirements. The importance of various aspects of
maintenance in order to maintain the same performance requirements as the base
aircraft structure is presented.
The subject of design substantiation will comprise a major
segment of the tutorial. Design substantiation covers many discussion points,
including, for example, survivability, the importance of achieving repeatable
results, and lightening protection requirements. A major focus area will be
structural substantiation. |
