We’re in the midst of a New Space Age. Space data use and emerging in-space infrastructures are increasing the demand for more powerful payloads and capacity of satellite constellations. But that doesn’t mean we’re launching bigger, heavier objects into space. Every mm² and every mg is accounted for, so that we can send more payloads into orbit.

Best-in-class thermal conductivity and lowest thermal resistance lets Carbice move heat away from high-powered components. Carbice® Space Pad enabled satellites can get smaller while increasing performance.
Carbice Space Pad excels at heat removal for spacecraft interfaces - large and small. This means you can have fewer heat pipes. And radiators can shrink in size.
Carbice Space Pad weighs <50% of SilPad or Mapsil. Direct replacement alone saves 2kg for a 32 satellite launch—a ~$20K savings! Size reduction and structural design optimizations delivers additional weight savings.
Meets performance requirements for satellites with 10-15+ year design-life, TRL9 qualified. Outgassing, corrosion, radiation, shock & vibration, FOD, thermal cycling are all compliant to MIL and meet ASTM standards with guaranteed end-of-life stability.
Built to last using recycled Al and waste gas. Minimizes waste at every step: Carbice SIM allows design in shorter iterations, precise sizing delivers material cut to spec, use the same Carbice Pad for both ground test and flight.
Design with confidence: Carbice SIM simulation matches TVAC result ±10%. Apply with ease: Simple peel-and-stick, both for initial application and rework. Re-order effortlessly: the entire process is digitized.

Large Bolted Interface

Space Pad™ cools Large Bolted Interfaces better, with confidence

Spacecraft face the harshest environments for thermal management, with intense radiation, large temperature variation, and limited ways for heat to move.

Machining errors and bowing issues make large bolted interfaces non-uniform.

In reality, large bolted interfaces have thermal gradients even with liquid TIMs.

Digital transformation of satellite design with Carbice
Carbice SIM predicts Space Pad performance with >90% accuracy.

For conventional TIMs, simulated performances could mismatch TVAC results by >50%. On the contrary, performance of Space Pad can be accurately simulated by our modeling tool - Carbice SIM.

  • Space Pad outperforms liquid TIMs and exceeds customer thermal requirement for large bolted interfaces.
  • TVAC result of Space Pad matches Carbice SIM result within ±10%.

Game changing customization
Structured Space Pad™

We can map and model your entire interface to create Structured Space Pad customized for your large bolted interface. For instance, when you have a hotspot, you can force better contact with Structured Space Pad.

Experience digital transformation of satellite design with Carbice

Step 1:
Share your assembly design with our team.
We will interface and work within your model securely. 

Step 2:
Using our Carbice SIM software, we capture and predict performance accurately.

We help you lower the cost of generating drawings, and help you reach optimal thermal performance and power density with unprecedented design speed. 

Small changes with big results: As an example, by adding center bolts on a particular prototype:

  • Increases conductance to 1.7X
  • Reduces peak delta T by 75%
  • Reduces weight by 40% if kept at the same conductance

 These kinds of optimizations allows engineers to design the next satellite with only half the surface area needed for cooling.

Step 3:
We prepare a small batch of samples.

We produce small batch samples with cutouts and boltholes matching your design to achieve the optimal thermal performance shown in our simulations. These samples are ready for testing.

Step 4:
When you receive the samples, follow the simple instructions to add Space Pad to your assembly. 

Carbice Space Pad is as easy as peel and stick. No more painting, drying or scraping as with liquid TIMs.

Step 5:
Test your assembly. You’ll note the TVAC results agree with the Carbice SIM results within 10%.

The same Carbice Space Pad can be used in ground test and in flight with no loss in performance, no more re-painting, re-drying or re-scraping.

Step 6:
Easily integrate Space Pad into your manufacturing operations and supply chain.

Carbice Space Pad is easily added to any existing or innovative assembly process, and allows you to revolutionize your ability to lower inventory cost and lead time, while enabling you to:

  • Save time,
  • Streamline labor,
  • Reduce weight,
  • Shrink size,
  • Lower the costs of annual spacecraft build

Carbice Space Pad is guaranteed to provide consistent performance and outlive your mission.

With Carbice, the added mass is low and precut sizes ease assembly. This is very important for us.
