Composite Curing Heater Blankets

Tempco’s composite bonding and curing heater blankets are designed with:

extra strong strain relief
even heat distribution to produce the best possible cure or bond

Temperature uniformity is optimized for even heating through computer designed resistance elements. Circuit spacing is maintained at 1/4" for larger heater blankets or less on smaller heaters. This technique guarantees a ±10°F (±5.5°C) temperature uniformity across the heater blanket.

The lead wires exit the heater through an unheated 2" × 2" lead exit tab. This allows the overall heater surface to be heated while maintaining a separate unheated section for the transition from resistance element to the leads and a solid strain relief.

Thermal Mapping

In the composite repair industry quality of the overall repair often relates directly to the quality of the cure. The cure is directly affected by the temperature uniformity of the heat blanket. Thermal/heat mapping certification of the heater blanket is rapidly becoming the standard operating procedure for many repair facilities to optimize the cure process.

As an added value service, Tempco can certify that the heat blanket you order follows the guidelines established by the Commercial Aircraft Composite Repair Committee (CACRC), SAE document ARP 5144 Section 7, which states specific recommendations for the “…handling, maintenance and thermal testing of heat blankets…”

The heater blanket certification also meets the requirements of Boeing document D6-56 273 “Qualification of Heat Blankets for Hot Bonding Composites.”
