Composite Damage Detection

The performance and behavior of composite structures can be significantly affected by degradation caused by exposure to environmental conditions or damage caused by handling conditions, such as impact, loading, abuse, or neglect. Such damages are not always visible on the surface and could potentially lead to catastrophic structural failures. To ensure a structure’s performance and integrity, timely and accurate recognition of damages is crucial. Acellent’s Composite Health Monitoring System addresses this specific challenge.

This system is ideal for monitoring large composite structures such as aircraft wings, fuselage, wind blades, and pressure vessels. The system identifies damages such as delaminations and disbonds. It identifies the onset of damage in the structure and also quantifies the damage size.

EXAMPLES

Monitoring of Composite Pressure Vessel/Rocket Motor Case

An integrated SHM system has been designed by Acellent to detect damage in composites due to impact and other sources. Acellent’s SMART Layers were embedded inside filament-wound sub-scale rocket motor during the manufacturing process. When damage occurs, either visible or hidden, the system can graphically display the location of the damage with its relative severity.

Large Scale Composite Damage Detection

Structures made of composite materials are lightweight and strong, but can suffer disbonds . Acellent’s SHM system has the ability to monitor large Composite Structures. Our goal is to provide early notification of performance degradation, potential problems or failures allowing structural users to schedule maintenance, avoid unanticipated downtime and ensure maximum uptime.

Benefits

Detection and quantification of hidden damage

Precise identification of damage location

Significant time savings for inspection of large composite structures

Cost-effective inspection of inaccessible structures, without any required structural teardown

Easy to use
