Textiler Formkörper mit Hitzeschild für automobile wie Stirnwandisolation o.dgl.Textile molded body with heat shield for automobiles such as bulkhead insulation or similar.
Zur Ausstattung von Automobilen werden Formkörper aus mit Bindemitteln verfestigten Fasern an mehreren Stellen eingesetzt. Sie basieren auf Reißgut z.B. Baumwolle, als Bindemittel fungiert Phenolharz.Molded bodies made of fibers bonded with binding agents are used in several places to equip automobiles. They are based on shredded material, e.g. cotton, and phenolic resin acts as a binding agent.
Sinn und Zweck des Einsatzes solcher Formkörper ist die Schallabsorbtion. Demzufolge finden sie Verwendung sowohl im Fahrgastraum wie auch im Motorraum.The purpose of using such molded bodies is sound absorption. As a result, they are used both in the passenger compartment and in the engine compartment.
Durch die moderne Bauweise der Automobile nun treten im Motorraum örtlich so hohe Temperaturen auf, daß die Komponente Baumwolle der Formteile hinsichtlich ihrer Beständigkeit unzureichend ist. In solchen Fällen bringen Hitzeschilder Abhilfe.Due to the modern design of automobiles, temperatures in the engine compartment are so high that the cotton component of the molded parts is insufficient in terms of its durability. In such cases, heat shields provide a solution.
Es gibt Hitzeschilder verschiedenartiger Konstruktionen. Angeführt seien vor allem Jene aus Aluminiumfolie an der Oberfläche, die mit anorganischem Fasergut d.h. mit Stein- oder Glaswolle hinterlegt sind.There are heat shields of various designs. The most common are those made of aluminum foil on the surface, which are backed with inorganic fibers, i.e. rock or glass wool.
Im Großen und Ganzen bewähren sich die herkömmlichen Hitzeschilder. Sie haben Jedoch den Nachteil, daß sie - eben wegen der Geschlossenheit ihrer Oberfläche - die Schallabsorbtionsfähigkeit eines Teiles wesentlich minder und ferner daß sie bei komplizierten Konturen nur unter großem Aufwand appliziert werden können.On the whole, conventional heat shields have proven themselves. However, they have the disadvantage that - precisely because of the closed nature of their surface - they significantly reduce the sound absorption capacity of a part and, furthermore, that they can only be applied with great effort to complicated contours.
Bei dem erfindungemäßigern Formkörper mit Hitzeschild bleibt die Schallabsorbtionefähigkeit wesentlich erhalten, extreme Formfähigksfit ist gegeben.With the inventive molded body with heat shield, the sound absorption capacity is essentially retained, and extreme moldability is provided.
Das erfindungsmäßige Formteil ist ein textiler Formkörper, bei dem örtlich eine poröse Metuli»ohicht aufgetragen ist. Dieses kann beispielsweise im Fl«MM»prltzv«rfahren erfolgen.The molded part according to the invention is a textile molded body, to which a porous metal layer is applied locally. This can be done, for example, using the FLAME PROCESSING process.

Beispiel Ii Ein textiler Formkörper aus Reißbaumwolle mit (Bild 1) a abgedeckt mit Polyesterfaservlies b ist örtlich - im Bereich extremer Hitzebeanspruchung mit einer Aluminiurnschicht c beaufschlagt.Example II A textile molded body made of shredded cotton with (Figure 1) a covered with polyester fiber fleece b is locally - in the area of extreme heat stress exposed to an aluminum layer c.
Beispiel £i Ein textiler Formkörper, der unter Beispiel 1 (Bild S) beschriebenen Art, ist örtlich mit einem Faservlies aus Glasfasern d belegt. Das Glasfasei— vlies ist zusätzlich mit einer porösen Aluminiumschicht c beaufschlagt.Example £i A textile molded body of the type described in Example 1 (Figure 5) is locally covered with a fiber fleece made of glass fibers d. The glass fiber fleece is additionally coated with a porous aluminum layer c.
Beispiel 3: Ein textiler Formkörper wie im Beispiel 1 be- <Bild 3) schrieben ist örtlich mit einem Mineral faservlies d und nach außen hin mit einem Glasgewebe e abgedeckt. Das Glasgewebe ist zusätzlich mit einer porösen Aluminiumschicht c beaufschlagt. Example 3: A textile molded body as described in Example 1 (<Figure 3) is covered locally with a mineral fiber fleece d and externally with a glass fabric e. The glass fabric is additionally coated with a porous aluminum layer c.
