Space and satellite


Widely used in spacecraft and satellites, TenCate's advanced composites deliver unsurpassed reliability and performance.  With an extensive spaceflight heritage, almost every space program in the Western world utilizes TenCate materials. The harsh rigors of space combined with the absolute need for reliability demand composites that can withstand repeated exposure to temperature extremes and radiation. TenCate materials pass strict NASA and European standards for outgassing and moisture resistance while resisting microcracking. With decades of successful missions, TenCate materials can help your program reach new heights.

With an industry-leading selection of ultra-high modulus fibers and specialty weaves, these spaceflight approved advanced composites create the strongest and lightest weight structures possible. Used on:

  • bus structure,A2100_Sattelite_Snagit_02
  • solar panels,
  • reflectors, heat shields, and 
  • a variety of booms, tubes, and trusses.

TenCate has a full suite of compatible:

  • cyanate ester and epoxy prepregs, 
  • resins, 
  • syntactics and
  • film adhesives. 

TenCate’s line of cyanate ester prepregs provides the highest performance, while our epoxy products meet the rigors of space flight while providing a more cost-effective alternative to cyanate ester materials.

TenCate provides composite materials for the space and satellite market from our Morgan Hill and Fairfield CA  facilities. We serve the European space and satellite market from our Langley Mill, UK manufacturing center of excellence.

Featured product

TenCate RS-36 is an advanced modified epoxy system for structural composite applications such as satellites and related satellite structure. RS-36 offers an excellent balance of mechanical properties, low moisture absorption, high glass transition temperatures and a range of processing options. A slightly higher Tg version is available, called RS-36-1, with similar mechanical properties.
