| 摘要 |
The invention relates to a composite panel with a thermosetting cellular matrix, to a method for manufacturing said panel, and to a structure for covering a wall that is formed from an assembly of such panels. Said structure provides the wall with heat insulation against cryogenic fluids and/or protection against fire or flames and/or sealing against said fluids. A panel according to the invention, having a thermosetting cellular matrix (9), comprises at least one substrate (1) that includes short, non-woven basalt fibers (2a, 3a, 4a, 5a) and is impregnated by said matrix. The panel is such that the at least one substrate includes a plurality of non-woven layers (2, 3, 4, 5) stacked to a stacking thickness (e). The non-woven layers each comprise the short basalt fibers and are needled through said thickness without using thermoplastic fibers. |
