Embodiment

[0101] Hereinafter, although an Example and a comparative example demonstrate this invention more concretely, this invention is not limited to a following example.

[0102]

[0103] (base weigh)

[0104] The obtained inorganic fiber sheet was measured based on JIS P8124.

[0105] (thickness)

[0106] The obtained inorganic fiber sheet was measured based on JIS P8118.

[0107] (Tensile Strength)

[0108] The obtained inorganic fiber sheet was measured by a method according to JIS P 8113 using a Tensilon type tensile tester (manufactured by ORIENTEC).

[0109] (bending resistance)

[0110] The obtained inorganic fiber sheet was measured by the method based on ISO2493 using the bending strength tester (BENDING RESISTANCE TESTER) (made by L&W company).

[0111] (folding times)

[0112] For the obtained inorganic fiber sheet, according to the JIS P 8115 flexural strength test method, the MIT (Massachusetts Institute of Technology, MIT) testing machine was used to calculate ...

Embodiment 2

[0134] The organic fibers were changed to polyethylene terephthalate fibers (diameter: 5 μm, length: 5 mm, aspect ratio: 1000), and the basis weight, thick inorganic fiber sheet.

[0135] Thereafter, measurement and evaluation were performed in the same manner as in Example 1. The results are shown in Table 1.

Embodiment 3

[0137] The organic fibers were changed to polyethylene terephthalate fibers (diameter: 8 μm, length: 5 mm, aspect ratio: 625), and the basis weight, thick inorganic fiber sheet.

[0138] Thereafter, measurement and evaluation were performed in the same manner as in Example 1. The results are shown in Table 1.

Abstract

The inorganic fiber sheet contains glass fibers as a main component, while containing 3-20% by mass of organic fibers relative to the total mass of the inorganic fiber sheet, the organic fibers havingaspect ratios of 300 to 2000.

Description

technical field [0001] The invention relates to an inorganic fiber sheet, a honeycomb shaped body and a honeycomb filter. [0002] This application claims priority based on Japanese Patent Application No. 2016-207709 for which it applied in Japan on October 24, 2016, and uses the content here. Background technique [0003] Since ceramic fibers have characteristics such as high heat resistance, high heat insulation, and non-combustibility, inorganic fiber sheets using ceramic fibers are widely used. For example, the inorganic fiber sheet is used as a support for functional materials such as heat insulating materials, heat-resistant cushioning materials, heat-resistant shielding materials, separators, and catalysts. Furthermore, the formed honeycomb body obtained by corrugating the inorganic fiber sheet is used as a honeycomb filter for heat exchange or a honeycomb filter for gas adsorption carrying a functional material such as an adsorbent. [0004] For example, Patent Doc...
