Title:
ミリ波を遮蔽する熱可塑性樹脂炭素繊維複合材および遮蔽部材
Document Type and Number:
Japanese Patent JP7379649
Kind Code:
B2
Abstract:
To provide a millimeter wave radar device which suppresses reception of millimeter waves reflected from other than a target obstacle, can control shielding performance of a shielding member mounted on a millimeter receiver, and improves detection accuracy.SOLUTION: A thermoplastic resin carbon composite material is composed of a thermoplastic resin carbon fiber composite material containing a thermoplastic resin and a carbon fiber, contains 5-50 wt.% of a carbon fiber, and shields millimeter waves having a ratio of carbon fibers with a fiber length of 0.01-0.5 mm of 60 wt.% or more in the total carbon fiber.SELECTED DRAWING: Figure 1
