MMS15 Interactive Knowledge Base (IKB) on NDE of
Composites 19 October 2005 Martin Wall National
NDT Centre, Paul Knights NetComposites, Anne

Objectives

• Development of an Interactive Knowledge Base
  (IKB) on NDE of composites
• Transfer of NDE expertise across industry
• A single focal point for industry on NDE of
  compositesthe IKB .on your desk
• An NDE forum for exchange of practical and new
  information (Technology transfer)
• A live IKB that will evolve and grow with time
• Inclusive of all industry sectors and NDE
  methods.
• A step change in the use of NDE by UK industry. A
  gain in the quality of composite components.

What questions will the IKB answer

• Is the equipment portable and usable in the
  field?
• What size of defect will it find?
• Is it applicable to my application?
• Are there procedures and standards I can use?
• What does the data look like and show me?
• Will it work in my composite fabrication?
• Can it size and characterise the defect?
• What is the status of the method?
• What are the limitations?
• How do I use the data in defect assessment or
  design?
• Who else in my sector is using the method?
• ...

...An authoritative answer..all in one place.

Technique Selection Tool

Technique Selection QAs

• Purpose What is the purpose of the inspection?
• Timing When and where is the inspection to be
  carried out?
• Material What is the composite material to be
  inspected?
• Sandwich What is the core Material? Dependent
  on answer in 3
• Geometry What is the geometry of the area to be
  inspected?
• Defect What type(s) of defect are to be
  detected/sized?
• Position What is the distance through the
  component to the defect (usually defect depth)?
  Dependent only if monolithic
• Position What is the through wall position of
  the defect in the component? Dependent question
  sandwich only
• Thickness What is the skin thickness of the
  component? Dependent on sandwich and defect not
  in top skin
• Thickness What is the thickness of the
  component Dependent question for Sandwich, only
  if defect in core or below.
• Coating Is the component coated?
• Surface What is the surface condition?
• Access Is access to the defect by NDE technique
  restricted
• Procedures Must procedures and standards be
  available?
• Performance Which is more important Cost of
  Inspection, Speed of Inspection?
• Inspectors How skilled can you afford the
  operator to be?

Technique Selection Results
COMMON Specialised,
Developmental
Specialised techniques simply given in
alphabetical order, no ranking, but can view
scores
23
Scoring Process Common

• For each answer on the spreadsheet give integer
  score from 0 (rules out) to 10 (no effect). Also
  put a simple comment to indicate the basis for
  the score e.g Radiography poor for cracking ,
  difficult in this thickness etc.
• Gut feel on how a factor could affect the
  technique.
• ? Against score if uncertain and amplify in
  comment and amplify in the comment.
• simple overall comment about experience with the
  method.

Score 10 No effect 7-9 Slightly limits
5 Limits (effectiveness reduced by 50
) 2-3 Significantly Limits 0 Rules out
technique ? Uncertain

• Same scoring process
• Users see separate list alphabetical order our
  experts suggest the following specialised or
  developmental techniques could be worth
  considering

Audit process

• Audit focused on COMMON techniques. Important
  these robust and correct
• Separate and simpler process used for SPECIALISED
  DEVELOPMENTAL techniques
• Common Techniques
• Invited IKB content to be reviewed by experts,
  project team, suppliers, IAG, users
• Gaps, additional data, comments
• Invited specific experts to Score common
  techniques for Technique Selection Tool
• Scores were independently audited by Steve Burch
  AEAT, Robert Smith QinetiQ
• Test runs by project team, IAG and others. Are
  suggestions sensible
• Specialised and Developmental
• Specialised and developmental ranked by project
  team and audited with comment invited from
  specific experts
