Title:
FIBROUS MATERIAL IMPREGNATED WITH THERMOPLASTIC POLYMER HAVING THICKNESS OF 100 μM OR LESS, AND ITS PRODUCTION METHOD
Document Type and Number:
Japanese Patent JP2023027050
Kind Code:
A
Abstract:
To provide an impregnated fibrous material with homogeneous impregnation of fibers, having controlled dimensions with a reduced, controlled and reproducible porosity and a homogeneous distribution of the fibers.SOLUTION: An impregnated fibrous material includes a fibrous material consisting of continuous fibers and at least one non-reactive thermoplastic polymer matrix. The at least one non-reactive thermoplastic polymer is an amorphous polymer with a glass transition temperature such that Tg≥80°C, notably Tg≥100°C, in particular Tg≥120°C, notably Tg≥140°C, or a semicrystalline polymer with a melting temperature Tf≥150°C. A fiber content in the pre-impregnated fibrous material ranges from 45 to 65 vol.%, preferably from 50 to 60 vol.%, notably from 54 to 60 vol.%. An average thickness of the impregnated fibrous material is 100 μm or less, irrespective of the number of fibers present in the fibrous material before impregnation.SELECTED DRAWING: None
