(6) filament of making by at least a aromatic polyamides.
Described forcing press pad can be the individual layer braiding or multi-layer braided.
The present invention also provides a kind of forcing press pad, it is characterized in that, it is interwoven by filament made from at least a aromatic polyamides and at least a following fine rule, and described one group of fine rule comprises:
(1) the heat-resisting silk of making by at least a rubber;
(2) the heat-resisting silk of making by at least a polysiloxanes;
(3) the heat-resisting silk of making by at least a flexiplast;
(4) comprise an outer and metal-cored filament, described skin is made above-mentioned (1) by using, (2), (3) planting the filament that at least a material in the material of filament makes constitutes, and the described metal-cored silk that is made of at least one fiber made from at least a metal material constitutes, and described metal material comprises metal and metal alloy;
(5) by employing at least a manufacturing above-mentioned (1), (2), the fibrous filament that is wound that the material of (3) or (4) kind filament is made is the wire of being made by at least a metal material in order to what twine it, described metal comprises metal and metal alloy.
Described forcing press pad can be the individual layer braiding or multi-layer braided.
But, not claimed for the combination of the line of the 1st group of material and 2.6 groups, because it is open in based on the prior art of United States Patent (USP) 5298322.
People can select the diameter of the material of 2.1-2.6 group according to desired liner effect.If necessary, the thickness of forcing press pad thereby the liner effect just followed also can reach by the single or multiple lift braiding.
Sometimes, for example in long pressure process, the thermal conductivity of forcing press pad is less important. in this case, following combination of materials also can obtain useful result:
I) a kind of combination in the material of 2.6 groups material and 2.1-2.5 group
II) some kinds of combinations in the material of 2.6 groups material and 2.1-2.5 group
2.4 the metal-cored of material of group can be made up of monofilament or multifibres.
To illustrate in greater detail the utility model according to embodiment below, from these embodiment, also can obtain other key character.Among the figure:
Fig. 1 shows the cutaway view according to forcing press pad of the present invention,
Fig. 2 shows the view of line used herein,
Fig. 3 shows 2.4 groups metal-cored material of multifibres,
Fig. 4 shows 2.4 groups metal-cored material of monofilament.
Accompanying drawing only shows some material according to a forcing press pad embodiment of the present invention; Complete composition can be by further obtaining in above-mentioned data and the claim.
Forcing press pad 10 shown in Figure 1 has the line of being made by for example aromatic polyamide filament 20 that interweaves and the heat-resisting silk of for example being made by rubber, polysiloxanes or the mixture of the two 30 made.

Fig. 4 shows a kind of modification embodiment illustrated in fig. 3, and this silk thread 70 comprises one metal-cored 71 and one skin 72, and wherein metal-cored 71 is to make with the single wire of for example copper or brass.
Example according to application or its combination of different silk thread materials of the present utility model is provided below.1. total situation
The forcing press pad wishes to have two key properties:
1. good liner effect (=tolerance compensating)
2. good thermal conductivity
In order to obtain good liner effect, people need a thick as far as possible forcing press pad.But when the thickness of forcing press pad increased, heat-transfer capability can degenerate in general.
In order to obtain good thermal conductivity, people need the material with good thermal conductivity as much as possible.But, if make the forcing press pad,, do not have the liner effect though this mat has optimal thermal conductivity with simple metal, this be because of, the mat of making of simple metal does not have recovery capability, this also just means does not have the liner ability.
Because the user has various plant equipment (forcing press), and produces various products, so the forcing press pad must satisfy the requirement that much has nothing in common with each other.With regard to certain customers, used new product usually requires to have corresponding adjustment and new development in the field of forcing press pad.Therefore, concerning various application scenarios, need between above-mentioned two kinds of extreme cases having found, try to achieve technology and the coordination of cost rationally.2. for example: I for example:
The mat that extraordinary liner effect is arranged: thermal conductivity is less important (very low).
The composition of mat: a kind of or some kinds of combinations of the material of 2.6 groups material and 2.1-2.3 group.Example II: the mat that has good thermal conductivity and good liner effect simultaneously.
The composition of mat: the combination of materials of 1.2 groups material and 2.5 groups.Example III: the mat of liner effect and thermal conductivity equilibrium.
The composition of mat: the combination of materials of 1.1 groups material and 2.4 groups.
