Sonic Testing of Aircraft Components for Composite flaws.

 

The Aerospace Flaw Detector    (PATENT PENDING)

Model# ACFD-2105

This custom built unit can help identify Composite Flaws, Delamination and Core Separation in most fiberglass structures, both cored and un-cored. Using sound, vibration, acoustic resonance and decibel measurement, this can help us to see flaws is composite structures.

The Aerospace Pinpoint Flaw Detector       (PATENT PENDING)

Model# ACFD-1310

The next step in our process is to Pinpoint more areas of potential flaws. This next level custom built unit can help identify Composite Flaws, Delamination and Core Separation in most fiberglass structures, both cored and un-cored. Using sound, vibration, acoustic resonance and decibel measurement, this can help us to see flaws is composite structures like never before.

 Identify Delamination in Aircraft Composite Structures

Many aircraft components are susceptible to fatigue, stress cracking, corrosion, and erosion after in-service life, and even one small defect undetected over time can cause failure. However, not every part of an airplane or helicopter is accessible to be visually examined by an inspector. This makes Sonic Testing an essential tool.

Our testing devices have a special design that enables inspectors to remotely examine difficult-to-access areas to check for composite flaws. The quality and design of the machine is essential. If an inspector does find a defect, the Sonic Testing Tool enables them to pinpoint it for documentation or to monitor it over time.

However, some flaws can’t be seen with the naked eye. Defects such as cracks and corrosion can accrue at load and stress attachment points, like frames and tabbing and even between fiberglass layers.

 Identify Bond Defects in Aircraft Composites Structures

Composites are increasingly common in the construction of aircraft, and some are made of more than 50 percent composites. Though they’re ideal for manufacturing aircraft because they’re lightweight and strong, it’s important to check composites for flaws. Depending on the nature of the composite part, impact strikes and other impacts can cause different types of damage. Among the most common are disbonds and delaminations, which both involve the separation of materials. Both of these flaws decrease component integrity.

​

Disbonds occur when the bond-line breaks between the adhesive skin to the core and the composite components. These disbonds weaken the composite and the overall integrity of the structure. It’s possible to visually detect some disbonds due to the damage that occurs as a result, but others are visually undetectable. Similarly, delaminations occur when the laminated Sonic  testing and bond testing can be used in place of less reliable inspections.

Sound waves, Acoustic Resonance, Decibel Analysis are used to test for bond issues. If and issues is detected (such as a disbond or delamination) exists, the composite component is either taken out of service or repaired and returned to service.
