Samenvatting

Grote reflector antennes moeten opgevouwen getransporteerd worden in de neuskegel van een raket. Er is geen andere oplossing. Daarom wordt gebreid reflector materiaal gebruikt met geringe massa per meter^2. In deze publikatie wordt het brei-proces besproken, op basis van Wolfraam draad (inderdaad zoals in de gloeilamp ook wordt gebruikt). Andere mogelijkheden zijn er (Molybdenum bijv.) maar Wolfraam is wat sterker.
