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;
- Scan increment should be no greater than one third the allowable damage limit size
- Differerence in thickness can cause the tap sound to change
- On large parts draw lines on the surface to make sure the inspection area is fully examined
- 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
- The tapping action must be controlled so that the surface of the component is struck using a light but firm action
- In areas where there is no delamination or de-(dis)bonding, tapping the surface of the component will produce a clear sound
- 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
- Tap the entire suarface of the inspection area in a square grip pattern of aproxemetly of 10 mm. (⅜"Inches)
- In areas where there is no de-or dis-bonding, tapping the surface of the component face sheets will produce a clear sound.
- In areas containing delamination/de or dis-bonding, the tapping surface of the compnent face sheets will produce a dull sound.
- Scan increments should be no greater than one third alloweble damage limit size.
- Differances in laminate thickness can cause the tap sound to change.
- On large parts, draw lines (with APROVED pencills) on the surface to make sure the inspection area are fuly examinated.
- 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.
- NDI inspectors and (certifing)Techicians performing tap testing are advised to do a hearing test.
