Welcome

• Thanks you for taking time from your summer
  activities to support this effort
• We appreciate the time each of you has spent on
  looking at the documents and preparing for the
  workshop.

Balancing Needs

• Interested Parties
• Customers, Current Potential - material
  quality
• Testing Labs - standardization of test methods
• Regulators - compliance with regulations
• Manufacturers - financial returns

Standardization
Testing Labs
Customers
Manufacturers
Regulatory Agencies
4
Specifications/Standards

• Past
• Little or no improvement in material performance.
  Meeting requirements was simply a badge of the
  wall.
• Development did not involve all interested
  parties.
• Insufficient return on investment or no business
  advantage.

• Future
• Material exceeds interested parties expectations.
  Meeting requirements means continual
  improvement.
• All interested parties share common values,
  culture of trust empowerment.
• Customer loyalty, retention of market share gain.

5
Specifications/Standards

• Past
• Quality Assurance was a post activity event,
  focused on inspection test after product was
  made.
• Quality Assurance acted as a regulator to control
  the supply of material. Sorted good products
  from bad authorized release of only good
  product.
• Collection of data.

• Future
• Quality Control focus on preventing failures
  during the process.
• Quality Control reviews key processes e.i. Last
  3 months of data to establish if the
  process/material properties are stable.
• Collection of data for a purpose.

6
Vision of Composites Control

• Current state of the art
• What we can do now
• Best Practice
• Short term improvements
• Two to five years to accomplish
• Current investigated new techniques
• Long term improvements
• Ten years
• Focused research to develop identified and yet to
  be discovered characteristics and techniques

Workshop Objectives

• The objectives of this workshop are to
• Review the results and recommendations of this
  FAA sponsored research on material procurement
  and material processing specifications.
• Assess current industry practice and recommended
  FAA directions for shared specifications and
  databases.
• Recommend further research activities where
  current quality assurance methods and techniques
  do not achieve a desired degree of composite
  materials reliability.

8
Review the results and recommendations of this
FAA sponsored research on material procurement
and material processing specifications.

• This Afternoon we will review and critique the
  documents.
• Each author will discuss the philosophy and
  technical details of their document
• A team of reviewers will give the workshop a view
  of the documents from their perspective.
• We have selected a diverse group of reviewers to
  get a broad view of these documents including
  suppliers, OEMs and regulators.

9
Assess current industry practice and recommended
FAA directions for shared specifications and
databases.

• On Wednesday
• We will divide into two groups to allow
  discussion on each document
• Material Procurement Criteria
• Material Processing Criteria
• These discussions will be summarized at the end
  of the morning.
• We will then as a group review key discussion
  areas developed in the morning breakout sessions.
• Thursday
• Develop the comments and criteria into useable
  actions. We will also discuss extension of these
  criteria to other processing techniques.
• Application of the control principles to new
  processing techniques.

10
Recommend further research activities where
current quality assurance methods and techniques
do not achieve a desired degree of composite
materials reliability.

• On Thursday we will explore the areas of
  composite control which are not well defined.
• Identify current QC techniques that need
  improvement.
• Determination of key characteristics that define
  an acceptable product.
• New techniques and procedures that will give the
  level of control and repeatability of a metallic
  material

11
Operating Procedures for the Workshop

• Please refrain from interrupting the
  presentations today. We have provided ample time
  for discussion. (A full day)
• Please wait to be recognized before asking
  questions or making comments.
• We will take a short five to ten minute break
  each hour.
• Each morning and afternoon there will be a
  refreshment break.
• A sponsored lunch is being held tomorrow in this
  room.
