Problems solved by technology

[0011] However, the insulating member disclosed in each of Patent Document 1 and Patent Document 2 is made of polymer resin only
Therefore, the insulating member has low heat resistance, and when the insulating member is hardened, the flexibility of the insulating member decreases
Therefore, the insulating member is not easy to store, and the workability of the insulating member is lowered

Embodiment approach 1

[0080] figure 2 is a flowchart showing the method of manufacturing the insulating member according to the first embodiment of the present invention. The method of manufacturing an insulating member according to the first embodiment of the present invention includes the steps of: crossing a plurality of glass fiber bundles in a lattice form to prepare a substrate configured as a plate-shaped mesh structure having holes formed therein; spraying adhesive on the substrate a step of coating an outer surface of each glass fiber bundle with a mixture; a step of drying the substrate on which the adhesive has been sprayed; and a step of cutting the substrate into a predetermined shape to obtain an insulating member.

[0081] Here, silicone rubber is used as the adhesive. like Figure 4 As shown, the finally fabricated insulating member 100 is constructed such that the outer surface of each of the plurality of glass fiber bundles 110 is coated with silicone rubber as the adhesive 120...

Embodiment approach 2

[0085] image 3 is a flowchart showing a method of manufacturing an insulating member according to a second embodiment of the present invention. A method of manufacturing an insulating member according to a second embodiment of the present invention includes: the steps of intersecting a plurality of glass fiber bundles in a lattice form to prepare a substrate configured as a plate-shaped mesh structure having holes formed therein; spray coating on the substrate as a a urethane resin of the binder to coat the outer surface of each glass fiber bundle; a step of drying the substrate on which the urethane resin has been sprayed; and a step of cutting the substrate into a predetermined shape to obtain an insulating member.

[0086] Embodiment 2 is the same as Embodiment 1, except for the following difference: In Embodiment 1, silicone rubber is used as the adhesive, while in Embodiment 2, urethane resin is used as the adhesive. like Figure 4 As shown, the final fabricated insula...

[0088] Figure 5 is a flowchart showing a method of manufacturing an insulating member according to a third embodiment of the present invention. A method of manufacturing an insulating member according to a third embodiment of the present invention includes: a step of crossing a plurality of glass fiber bundles in a lattice form to prepare a substrate configured as a plate-shaped mesh structure having holes formed therein; serving as a binder The second step of filling the holes formed in the substrate with the silicone rubber; the third step of drying and hardening the substrate filled with the silicone rubber; and the fourth step of cutting the substrate into a predetermined shape to obtain an insulating member. Figure 7 An insulating member manufactured using this manufacturing method is schematically shown in .

[0089] like Figure 7 As shown, the holes 130 formed between the glass fiber bundles 110 are filled with silicone rubber as the adhesive 120 to ensure the flex...
