Problems solved by technology

However, with this reduction in weight, the rigidity of the fiber base material itself gradually decreases, and it becomes difficult to secure sufficient rigidity (ie, handling rigidity) to withstand handling during handling.
Recently, the limit of the handling rigidity has become an obstacle to the further reduction of the weight of the fiber base material

no. 1 Embodiment approach ）

[0038] The fibrous base material 1 of the first embodiment will be described with reference to the drawings.

[0039] The fibrous base material 1 is a plate-shaped fibrous base material in which fibers are bonded with a thermoplastic resin. Furthermore, the fibrous base material 1 is characterized by having a plurality of regions having different basis weights.

[0040] Such as figure 1 As shown, the fibrous base material 1 of the present embodiment has a first region 3 having a larger basis weight and a second region 5 having a smaller basis weight than the first region 3 . in addition, figure 1 Different shades of shading in represent different weights per unit area. The darker the shade, the greater the weight per unit area ( Figure 3 ~ Figure 5 also the same). also, figure 1 Arrow FR in the arrow indicates the front side when the fibrous base material 1 is used for an automobile interior material.

[0041] The fibrous base material 1 of the present embodiment is...

no. 2 Embodiment approach ）

[0066] refer to figure 2 and image 3 The fibrous base material 1 of the second embodiment will be described. figure 2 of car interiors can have image 3 Fiber substrate 1. In addition, the same reference numerals are assigned to the same parts as those of the first embodiment described above, and descriptions of structures, functions, and effects are omitted. And, with figure 1 Similarly, the difference in shade shades indicates the difference in weight per unit area. Darker shades indicate greater weight per unit area. also, figure 2 and image 3 The arrow FR shows the front side of the car, and the arrow UP shows the upper ( Figure 4 also the same).

[0067] The fibrous base material 1 has a notch 7, and the basis weight of the peripheral region 9 of the notch 7 is larger than the basis weight of the outer region 11 outside the peripheral region. A notch 7 is formed in the fiber base material 1, and when the fiber base material 1 is installed as a roof materi...

no. 3 Embodiment approach ）

[0070] refer to Figure 4 The fibrous base material 1 of the third embodiment will be described. figure 2 of car interiors can have Figure 4 Fiber substrate 1. In addition, the same code|symbol is attached|subjected to the same part as said 2nd Embodiment, and description of a structure, operation|movement, and an effect is abbreviate|omitted.

[0071] and figure 1 The fiber base material 1 shown is the same, and the fiber base material 1 that can be used as the roof material of an automobile is configured with belt-shaped, larger areas per unit area at both edge portions, thereby making the rigidity of the fiber base material 1 both sides Becomes high. In addition, each notch 7 corresponding to a portion where each strut 15 is disposed is formed in the region where the basis weight is large. That is, each notch 7 corresponding to each strut 15 is arranged such that the notch 7 is included in a region with a large basis weight. Furthermore, the weight per unit area of...

Abstract

The present plate-like fiber base material has fibers and a thermoplastic resin. The fibers are bound by the thermoplastic resin, and the fiber base material includes a plurality of areas that differ in basis weight. The fiber base material may have a cut, and the basis weight of a cut-surrounding area positioned around the cut may be higher than that of an area positioned around the cut-surrounding area. The present interior material has the fiber base material and a surface layer that is disposed on one side of the fiber base material.

Description

technical field [0001] The invention relates to a fibrous base material and an interior decoration material using the fibrous base material. Background technique [0002] In the past, in a wide range of product fields such as vehicle interior materials such as car floor trims, roof trims, and door trims, as well as building materials such as floors, roofs, and carpets, a type of thermal insulation, sound insulation, and cushioning has been used. Fiber substrates such as the intended plate shape. [0003] From the standpoint of environmental load, cost reduction, etc., these fiber base materials are being reduced in weight day by day. However, with this weight reduction, the rigidity of the fiber base material itself gradually decreases, and it becomes difficult to secure sufficient rigidity (ie, handling rigidity) to withstand handling during handling. Recently, this limit of handling rigidity has become an obstacle to further weight reduction of fiber base materials. Reg...
