Description

Composite fiber felt for automotive interior

Technical Field

The utility model belongs to the technical field of combined material for automotive interior and preparation technology thereof, concretely relates to combined material fibrofelt for automotive interior.

Background

The car door provides the passageway of cominging in and going out the vehicle for driver and passenger to isolated outer interference, to a certain extent, alleviate the side impact, protect the pleasing to the eye of passenger and car also relevant with the molding of door, the good or bad of door performance mainly embodies: the crashworthiness of door, the sealing performance of door and the convenience index etc. that opens and shuts of door, wherein, crashworthiness is especially important, because when the vehicle takes place the side impact, buffer distance is very short, if door crashworthiness is not good, just causes the injury of personnel in the car very easily.

Taking a common impurity hopper in an automotive interior as an example, the impurity hopper is a welded part arranged in an automotive door panel interior assembly, and a vehicle user can place impurities such as water, a map and the like.

In addition, in order to ensure the mechanical properties of the automotive interior material, the existing automotive interior material is relatively complex in structure and relatively thick in material dimension, so that the material cost is too high, the weight is relatively large, the lightweight design of a vehicle is not facilitated, and the dimensional stability of the material is relatively poor.

SUMMERY OF THE UTILITY MODEL

To the defect that exists among the above-mentioned prior art, the utility model discloses a combined material fibrofelt for automotive interior not only can make automotive interior spare part all show the promotion in the aspect of lightweight, mechanical properties and dimensional stability, can also effectively avoid long-time the use because of moisture absorption, go mildy and produce peculiar smell, increase of service life.

With the attached drawings, the technical scheme of the utility model is as follows:

a composite material fiber felt for automobile interior decoration comprises a composite inner layer 1, an adhesion layer 2 and a composite outer layer 3;

the composite inner layer 1 is a composite chemical reinforced fiber layer, and composite chemical reinforced fibers in the composite chemical fiber layer are formed by mixing PET fibers and PP fibers;

the composite inner layer 1 and the composite outer layer 3 are fixed by the adhesion layer 2 through mould pressing, heating, bonding and fixing.

Further, the composite outer layer 3 is a PET carpet velvet fabric layer.

Further, the adhesion layer 2 is a granular hot melt adhesive layer.

Compared with the prior art, the beneficial effects of the utility model reside in that:

composite fiber felt for automotive interior to the compound chemical fiber that PET fibre and PP fibre constitute forms compound inlayer, and bonds through tie coat and the compound outer hot pressing that adopts PET blanket fine hair surface fabric to form, makes the interior trim part that adopts this composite fiber felt to make subtract heavy, mechanical properties and dimensional stability in the aspect of, all show the improvement than traditional material part.
