In the field of space propellant tanks, emphasis has focused on the demisablity of the tanks – that is to say that, designers are looking for tanks which are capable of complete disintegration during re-entry and jettison. Current designs based on metallic constructions, can fail to fulfil this criteria. Thus, more and more tank producers are looking towards 100% plastic tanks to reach this objective. Holscot is proud to say it can offer a developmental solution for this demand.
Using experience gained from over 50+ years providing fluoropolymer lined tanks and vessels to chemical and pharmaceutical companies worldwide, Holscot utilise FEP laminate for their solution. FEP laminate material has a woven fabric embedded into it. Constructing the tanks with the fabric on the outside of the fabrication, composite materials can then be laid up on the surface to eventually form a fully homogeneous structure.
The carbon fibre lends itself to being further reinforced making a strong, lightweight, quick to construct and more easily demisable construction.
The techniques that Holscot bring to these constructions – such as welding and thermoforming – have been the cornerstones of Holscot’s expertise and enable constructions of a huge variety of sizes and shapes to be possible.
Using FEP as an internal liner also facilitates the use of a FEP diaphragm for encouraging complete expulsion of the propellant which can be attached to the liner itself.
More details on projects already completed can be seen in our Case Histories.
