B- Tap Hammer

The B- Aluminium tap hammer, is used to detect delamination (separation of plies) and disbonds from te core in advanced composite structures.

This tap Hammer is a must have, for Composite Repair Technicians, Composites certifying staff Composite engineers and Quality inspectors to perform a correct damage assessment in thin laminates and metal bonded parts! 
It is fabricated to OEM standard drawings and sizes and anodized for a better protection of the material. Material used is   Alum type EN_AW_ 6082-T6

Tap test inspection Method;

  1. Scan increment should be no greater than one third the allowable damage limit size
  2. Differerence in thickness can cause the tap sound to change
  3. On large parts draw lines on the surface to make sure the inspection area is fully examined
  4. Taps hammer testing is not reliable on face sheets with more than 3 plies but tap testing is allowed to determine the extent of lightning strike damage on any thickness composite structure
  5. The tapping action must be controlled so that the surface of the component is struck using a light but firm action
  6. In areas where there is no delamination or de-(dis)bonding, tapping the surface of the component will produce a clear sound
  7. In areas containing delamination or de-(dis)bonding, tapping of the component will produce a dull sound
DO NOT STRIKE SURFACE OF COMPONENT WITH TOO MUCH FORCE. DAMAGE MAY OCCURE!

Using tap-test tool
  1. Tap the entire suarface of the inspection area in a square grip pattern of aproxemetly of 10 mm. (⅜"Inches)
  2. In areas where there is no de-or dis-bonding, tapping the surface of the component face sheets will produce a clear sound.
  3. In areas containing delamination/de or dis-bonding, the tapping surface of the compnent face sheets will produce a dull sound.
  4. Scan increments should be no greater than one third alloweble damage limit size.
  5. Differances in laminate thickness can cause the tap sound to change.
  6. On large parts, draw lines (with APROVED pencills) on the surface to make sure the inspection area are  fuly examinated.
  7. Tap testing is not reliable on facesheets with more than 3 plies but tap testing is allowed to determine the extent of lightning strike damage on any thickness composite structure.
  8. NDI inspectors and (certifing)Techicians performing tap testing are advised to do a hearing test.
