Abstract
The invention relates to a long fiber-foam composite material, in which the long fibers are bonded to form a loose but dimensionally stable structure with good recovery properties. The long fibers are only partially bonded by foam particles in the shape of nodal points. The foamed or unfoamed foam particles are applied to the structure when the latter is being formed. The unfoamed foam particles applied to the structure are foamed by reacting or reactivating the blowing agent previously applied to the bonding agent to be foamed. The expansion can freely take place without limiting the volume so that a minimal possible thickness can be obtained by complete expansion or in a predetermined volume having a predetermined thickness, for instance, by expansion in a double wall press or a mold.
Claims (15)
1. Long-fiber foam composite in which the long fibers are only partially connected to a structure of low density with bonding small foam bodiesparticles, wherein the bonding small foam bodies are put into the padding in either expanded or non-expanded form during the formation of said padding and the small foam bodies put in in non-expanded form are thereby expandable through reaction or through activation of foaming agent previously put into the binding agent to be expanded.
Claims
Claims
2. Long-fiber foam composite according to Claim 1, characterized in that the nodally arranged bonding small foam bodies are put into the padding in either expanded or non-expanded form during the formation of said padding.
3. Long-fiber foam composite according to Claim 1 or 2 characterized in that the small foam bodies put in in non-expanded form are expandable through reaction or through activation of foaming agents previously put into the binding agent to be expanded.
4. Long-fiber foam composite according to one of the Claims 1 to 3, characterized in that foam-free zones stretched across by fibers alone are formed between the small foam bodies.
5. Long-fiber foam composite according to one of the Claims 1 to 4, characterized in that the fibers used are natural fibers, chemical fibers, synthetic fibers, inorganic fibers, both as primary fibers and also as recycled fibers or mixtures thereof.
6. Long-fiber foam, composite according to one of the Claims 1 to 5, characterized in that the expansion proceeds freely without, volume restriction so that it is possible to achieve a minimally possible density through complete expansion.
7. Long-fiber foam composite according to one of the Claims 1 to 5, characterized in that the expansion can be carried out through a double-belt press, mold or similar predetermined volume with thereby predetermined density.
9. Long-fiber foam composite according to one of the Claims 1 to 5, characterized in that expanded polymer fibers are put into the fiber mixture and are fused together with one another at the crossing points through thermobonding.
9. Long-fiber foam composite according to one of the Claims 2 to 5, characterized in that polymer fibers containing foaming agent are put into the fiber mixture.
10. Long-fiber foam composite according to Claim 9, characterized in that the foaming agent is activatable through reaction or through input of energy during or after the formation of the padding and that the expansion can thereby be effected.
11. Long-fiber foam composite according to Claim 9 or 10, characterized in that the polymer fibers are fused with one another at the crossing points.
12. Long-fiber foam composite according to one of the Claims 1 to 11, characterized through compression to form molded parts through the input of energy and/or pressure in molds.
23. Long-fiber foam composite according to Claim 12, characterized in that that the molded parts have zones compressed to different extents.
14. Long-fiber foam composite according to one of the Claims 1 to 13, characterized in that a coating of adhesive or a foam coating capable of adhering is applied to one or both sides of the molded parts.
15. Long-fiber foam composite according to Claim 14, characterized in that surface coating materials of a decorative kind or with a technical function are glued on or foamed on.
