Abstract
Inventia se refera la un material fonoizolant format din doua paturi netesute, incluzând fibre discontinue, si la un procedeu de realizare a acestuia. Consolidarea fibrelor în paturi si a paturilor între ele se realizeaza prin intertesere si lipire, iar ambele paturi sunt impregnate cu un ignifugant. Patura superioara include fibre la prima folosire, de prefeirnta poliamidice sau poliesterice, iar patura inferioara include fibre poliacrilonitrilice, poliesterice si celulozice, care pot fi refolosite. Se revendica si un procedeu de ignifugare. Materialul se foloseste în special pentru izolarea capotelor motoarelor de automobil.
