Abstract (en)
[origin: WO2018007460A1] A composite sheet comprising at least a textile structure and a polyetherimide (PEI), the latter impregnating and densifying the textile structure, the sheet having a porosity of between approximately 3% and approximately 8% by mass of acetone sorption, and preferably between approximately 4% and approximately 5%, as measured by the acetone uptake method. The manufacturing method comprises continuous or semi-continuous moulding. This sheet can be used as a skin of a foamed structure made from PEI.
