AEROSPACE COMPOSITE REPAIRS

Acsion and Acetek continue to pursue E-beam repair certifications, as well as performing conventional repairs.  Acetek maintains its Authorized Maintenance Organization (AMO) status and our experienced work force capable of meeting all your maintenance needs.

E-beam repair is a revolutionary process.  As the world's aircraft manufacturers increase the number and complexity of composite parts in their aircraft, the need to repair damaged products in an even more timely and cost-effective manner becomes imperative.

The E-beam process is fundamentally different from thermal methods.  It is fast, in many cases easier to apply, requires no heat input, and saves both material and production costs, while improving part performance.  As well as composite-to-composite repairs, it can prove effective on several other material combinations:  composite-to-metal and metal-to-metal.

As a first step in certifyiing this process for aerospace applications, an EB repair on Airbus aircraft wing-to-body fairings has been approved by Transport Canada through release of a Repair Design Certificate (RDC No. C-RA03-059).  THIS IS THE FIRST APPROVED EB REPAIR APPLICATION IN AVIATION HISTORY.  In parallel with this approval, flight trials have been conducted on fairing and engine cowl components with repairs accumulating thousands of flight hours.

E-beam  Advantages

Faster turnaround times:

  • Shorter cure cycles
  • All repairs cured at one time
  • Co-cure of potting and patch

Reduced risk of in-process damage:

  • Eliminates damage caused by moisture expansion in core due to low heat during cure
  • Prevents under cure of repairs due to heat sinks in panels

Moisture ingress eliminated as E-beam repairs are not porous

Simpler tooling for larger, more complex repairs:

  • Low temperature cure, vacuum only
  • Custom heat blankets not required

Lower material costs:

  • Room temp. storage, extended shelf life leading to less scrap and lower inventory costs
