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.

6
Progress since July 2004

• Audit Strategy defined (September Meeting)
• Simplified and easier IKB structure
• Distinction Common v Specialised techniques
  -Different treatment
• Improved User Interface and Menus. New Main
  version of IKB on NC site
• Initial scoring complete for technique selection
  tool.
• Technique Selection Tool now implemented
• NDE Forum implemented
• Lot of new information. Detection of porosity
  etc.
• Sequential audit, processing and input of
  information to IKB
• Case studies Laser optical, composite repairs
• Website and members area updated
• Visits and interactions with IAG members, NDE
  Cos and users

7
Software Improvements

• New structure implemented
• New menus Net Composites Site
• NDE Forum implemented
• Score editor to edit and compare scores for TS
  tool
• Search and Feedback implemented NC site
• Technique Selection implemented Development site

8
Review Meeting September 2004

• AEAT, Qinetiq, Net Composites Full Project team
• Refined list of QAs agreed
• Strategy for audit of Content agreed
• Scoring and Audit of Technique Selection tool
  agreed
• Lists of techniques finalised Common,
  Specialised, Developmental
• IKB structure simplified
• 50 techniques in IKB Only 10 commonly used
  Focus audit and accurate scoring for
  theseInformation needs to be robust and correct.
  
• For specialised techniques important thing is to
  flag up. Less known on these but may need these
  for difficult inspection problems

9
Audit process

• Audit to focus on COMMON techniques. Important
  these robust and correct
• Separate and simpler process for SPECIALISED
  DEVELOPMENTAL techniques
• Common Techniques
• Invite IKB content to be reviewed by experts,
  project team, suppliers, IAG, users
• Gaps, additional data, comments
• Invite specific experts to Score common
  techniques for Technique Selection Tool
• Scores to be 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 but comment invited from specific experts

15
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?

16
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
17
Scoring Process Specialised, Developmental

• Simpler process
• Score answer
• 0 if showstopper
• S if significant effect,
• ? If uncertain
• 1 Otherwise
• Users see separate list alphabetical order our
  experts suggest the following specialised or
  developmental techniques could be worth
  considering
