CFRP Sandwich Panels
Background Heritage: ESA Technology Development programmes (TRP, GSTP)
Description
Since 2012, Adamant Composites has been establishing capabilities and developing industrial know-how to produce CFRP sandwich panels for satellites structures and instruments. An autoclave production line is established capable of Built to Print producing sandwich panels up to 2 x 1 m. The processing of epoxy and cyanate ester prepregs has been demonstrated through ESA activities. Thanks to in house established engineering capabilities also Build to Spec option is offered.
Key Points
Structural Panels, Instruments, Thermal Panels, Small satellites
CFRP Struts
Background Heritage: ESA Technology Development programmes (CTP)
Description
Lightweight space structures often employ one dimensional elements that provide high stiffness and strength in preferred directions. Adamant Composites has developed and qualified its own struts for demanding high end applications such as deployable structures. The struts consist of CFRP tubes with engineered layup to meet the loading and operation specifications and customized metallic end fittings. Adhesive bonding for the assembly of the struts has been qualified for use in vacuum for a broad temperature range.
Key Points
Balanced axial and bending stiffness and strength, dimensionally stable, Tailored-made design
Lightweight Stable Large Deployable Truss
Background Heritage: ESA Technology Development programmes (CTP)
Description
Adamant Composites is developing a modular, scalable, ultra stable deployable/stowable truss system, configurable to deployment lengths of up to 20m. Possible applications include spaceborne telescopes, SAR earth observation spacecraft as well as deployable masts for antenna reflectors.
Currently, an Engineering Qualification model for a deployable truss of 12m in length, 3.9m in diameter is being developed and expected to undergo full scale testing within 2020.
A 1:1 scale breadboard of 3m in deployed length has already been successfully tested, demonstrating the functionality of the truss and its actuation module, and verified the stiffness, repeatability and stability of the design. The truss structure, actuation system and associated MGSE are designed in-house. Component and subsystem level testing to EQM level have been completed.
The 12m long model is stowable to a height less than 1m, including its motorization system. The truss stability and repeatability allow it to deploy consistently with a positioning error below 1mm. The system is designed to be capable to operate in orbit with a Stability Ratio of 10e-4 while its stiffness for a 1000kg payload is > 3Hz.
Key Points
Large Stable Deployable Truss, Modular High Stiffness Deployable Structure
Deployable Antenna for Small Satellites
Background Heritage: ESA Technology Development programmes (TRP, GSTP)
Description
Adamant Composites is currently developing a deployable X-band reflector antenna for small spacecraft with the target of TRL7 in 2022. The size of the S/C targeted is 1m cube while the diameter of the reflector is 1.5 to 2m, with a gain more than 40 dBi. The structural design employs lightweight CFRP elements while the RF design utilizes standard and novel reflective mesh technologies.
Key Points
Small spacecraft, science missions, communication antennas, SAR antennas
