A process for forming a moldable, uncured nonwoven composite containing forming a outermost nonwoven layer, forming a structural nonwoven layer, needling the structural nonwoven layer and the outermost nonwoven layer together from both the outer surface of the outermost nonwoven layer and the second surface of the structural nonwoven layer, applying an uncured, water-based thermosetting resin having a cure temperature of at least about 160 C to the second surface of the structural nonwoven layer, and at least partially drying the uncured, wet nonwoven composite. Heat and pressure may be applied to form the moldable, uncured composite. A moldable, uncured nonwoven composite and a molded, cured nonwoven composite are also disclosed.

Formkörper (1), der einen Schaumstoff (5) und mindestens eine Faser (4a1, 4b1, 4c, 4b2, 4a2) umfasst. Die Faser weist einen ersten Teil (4a1, 4b1), einen zweiten Teil (4a2, 4b2) und einen dritten Teil (4c) auf. Der dritte Teil (4c) der Faser verbindet den ersten Teil (4a1, 4b1) und den zweiten Teil (4a2, 4b2) der Faser und ist auf einer zweiten Seite (3) des Schaumstoffs (5) angeordnet. Ein erster Bereich (4b1) des ersten Teils (4a1, 4b1) der Faser und ein erster Bereich (4b2) des zweiten Teils (4a2, 4b2) der Faser befinden sich innerhalb des Formkörpers (1) und berühren sich nicht. Ein zweiter Bereich (4a1) des ersten Teils der Faser und ein zweiter Bereich (4a2) des zweiten Teils der Faser ragen aus einer ersten Seite (2) des Schaumstoffs (5) heraus. Verfahren zur Herstellung des Formkörpers (1) sowie ein Paneel, das den Formkörper (1) und mindestens eine Deckschicht zur Erzeugung eines Sandwichlaminats enthält, sowie ein Verfahren zur Herstellung des Paneels. Verwendung des Formkörpers beziehungsweise des Paneels beispielsweise als Rotorblatt in Windenergieanlagen.
摘要:
The present invention relates to multi-layered composite structures and to methods for the preparation thereof. The present multi-layered composite structures are light weight and capable of high load bearing making the present multi-layered composite structures especially suitable to be used as load bearing structures in, for example, automotive. Specifically, the present invention relates to methods comprising the steps of a) providing a mould for said multi-layered composite structure; b) layering said mould with two or more layers forming the outer surface of said multi-layered composite; c) filling said layered mould with a mixture comprised of non- expanded heat-expandable microspheres and closing said mould; and d) subjecting said closed mould to a temperature of 80°C to 140°C during 1 to 230 minutes thereby providing a relative pressure in said closed mould of 0.1 to 20 bar through expansion of said heat-expandable microspheres thereby forming a multi-layered composite structure in said mould with a foam enforced inner core and a multi-layered outer surface; and e) separating the multi-layered composite structure from said mould.

摘要:
A flexible, self-supporting hybrid veil that is permeable to liquid and gas. The hybrid veil includes: (a) intermingled, randomly arranged fibres in the form of a nonwoven structure; (b) particles dispersed throughout the nonwoven structure, wherein a majority of the particles are penetrating through the thickness of the nonwoven structure; and (c) a polymeric or resinous binder present throughout the veil. Such hybrid veil can be incorporated into composite laminates, prepregs, fabrics and fibrous preforms.
