Embodiment Construction

[0061] figure 1The composite material 10 shown in is made of a central hard felt layer 12, on opposite sides of said central hard felt layer 12 a respective soft felt layer 14, 14' is arranged, wherein the individual layers 12, 14, 14' They are each connected to one another over a large area by means of adhesives (not shown). Here, the adhesive can be configured as an intermediate layer between two adjacent felt layers 12 , 14 or 12 , 14 ′. Alternatively to this, the adhesive can originate from the contact surfaces of adjacent mat layers 12, 14, 14'.

[0062] exist figure 2 In the composite material 10 shown, the individual layers are associated with figure 1 The layers of the composite material shown are of complementary construction, that is to say the composite material is produced from a central soft felt layer 14 , on opposite sides of which a hard felt layer 12 , 12 is arranged in each case. ′, wherein the individual layers 14 , 12 or 14 , 12 ′ are connected to each...

Abstract

The invention relates to a composite material comprising at least one layer of soft carbon fiber felt and at least one layer of hard carbon fiber felt, wherein the at least one layer of soft carbon fiber felt is connected to the at least one layer of hard carbon fiber felt via a binder.

Description

technical field [0001] The invention relates to a composite material, and in particular to a high temperature resistant composite material. Background technique [0002] Due to their high thermal stability and their chemical inertness towards substances present inside the furnace, carbon based materials are often used as thermal insulation in high temperature applications, for example as thermal insulation in high temperature furnaces. In order to avoid heat losses by heat radiation and heat losses by heat conduction and convection, it has been proposed to use composite materials, for example comprising carbon fiber reinforced carbon layers and thin graphite layers, as thermal insulation in high temperature applications. In this case, the carbon fiber-reinforced carbon layer in particular avoids heat loss by heat conduction, whereas the graphite thin layer acts reflectively and thus prevents heat loss by heat radiation. [0003] However, thermal insulation based on carbon f...
