Description of the invention (1) Cross-reference to related applications This patent is filed on April 23, 1997. US Patent Application No. 08 / Part of the serial case of 839,016 is incorporated herein by reference. BACKGROUND OF THE INVENTION The present invention relates generally to composite articles and, more particularly, to plastic non-woven fibrous composite articles. In the manufacture of articles containing polymer materials (which have sufficient strength and stiffness to be used as car box linings), a well-known operation is to use sheets of thermoformable material with different properties, process the sheets into layers, and then- Waiting in one mold to compress together under heat and pressure, using at least one layer can impart strength and stiffness and using another layer it produces a whole body sufficient for molding. U.S. Patent No. 5, 2 98, 3 1 9 discloses: a car box lining made from a fibrous composite material, the composite material has a non-woven fabric (basically composed of polypropylene short fibers) It consists of an outer layer and an intermediate layer composed of extruded polypropylene. These earlier art fibrous composite materials were simultaneously combined with the extruded intermediate polypropylene layer. The inner surfaces of the two outer non-woven fabric layers are adhered to the surface of the extruded polypropylene via the heat generated during the extrusion process and to the adjoining surface of the inevitable molten state that melts during the process. Use all three layers containing the same polymer (ie, polypropylene) to facilitate the final recycling of the article. Several disadvantages inherent in this earlier crafting procedure. Because the intermediate layer is extruded, which grants the necessary integral to molding, the objects molded from it must have a uniform thickness. Another disadvantage is that the fibrous composite must be combined with the extruded intermediate layer at the same time.

Description of the Invention (3) It is not limited to the manufacture of automobile roof pads, box linings, cabin components, luggage, furniture, sports equipment and The product was filtered. The selected polymeric chemicals are made into two different fabrics with different mechanical and / or other physical properties. At least one fabric is a formable fabric that has a relatively high degree of strength and stiffness when finally molded under heat and / or pressure. The other fabric is a changeable compression fabric (also described as a changeable thickness fabric) which can exhibit a changeable thickness and density when subjected to molding under heat and / or pressure. In some applications, where uniform thickness and density are required for the finished product, a variable compression fabric can also be used. This modifiable compression fabric is the subject of US Patent No. 5,5 3,2 0500 :, incorporated herein by reference. In another embodiment, another layer constituting the facing fabric may be applied to the outer surface of either layer for the purpose of enhancing the appearance of the article molded from the composite material. The functional layers and the fabric-facing layers of the layers can be combined to form a composite material that can be transported to the finished product by the manufacturer. Composite materials can be combined by stacking each layer on top of another and joining them together. The term π composite material, as used herein, includes any stack of successive layers, whether or not cohesive between or among layers, is strengthened by chemical and / or physical methods. The cohesion of the adjacent layers of the composite-material can be strengthened by the following techniques: • Spray powder bonding, using liquid dispersions / solutions, stitching, flame bonding, using intermediate adhesive fabrics between the functional layers and mechanical needle puncture, all These methods are well known to those skilled in the art. Also included in this concept is another specific embodiment in which a blend of selected fibers having a predetermined melting temperature range is included in either or both layers, which affects the adhesion between the layers of the composite material and the finished mold Plastic

Then you can put the car The top liner or box lining is formed by passing the composite material through a compression molding device, so that the composite material undergoes an elevated temperature and / or pressure for a period of time sufficient to make the composite material take the shape of a mold slot. Regarding the use in the present invention, It has been found that the basis weight of a formable or strong fabric should be from about 4 to 18 ounces per square yard. A preferred range is from about 6 to 12 ounces per square yard. These ranges provide processing power during manufacture , The most suitable combination for controlling the stiffness properties in the finished molded article and the economics of manufacturing the finished product. In another specific embodiment of the present invention, one piece of polyester changeable compression fabric is sandwiched between two pieces of formable Polyester (which is formed as a needling blanket) to form a composite material object. Needle blankets are manufactured by KK η ow 1 t ο η Nonwovens Co., Ltd., Utica, New York. The cohesion between adjacent sheets passes through Mechanical acupuncture The composite material is then rolled into a storage roll. A layer of decorative fabric, such as Η 0 FA Η MV V 8 printed stitch-bonded polyester or F 0ss needle-punched polyester, can be applied to each of the layers in the formable polyester fabric An outer surface of an article. An article, such as a car box lining or top gasket, is formed in a mold under heat and / or pressure. The molded article is then cooled to ambient temperature. US Patent Case No. 5 mentioned above No. 298, 319 teaches the basic molding steps and devices used to make such objects contemplated by the present invention, and is incorporated herein by reference. It should be understood that different methods of enhancing cohesion can be used between different fabric layers of the same composite. For example, the enhanced cohesion between the facing fabric layer and the formable fabric layer can be intermediated by inserting an adhesive layer

Description of the invention (7) to achieve, and the enhanced cohesion between the fabric layer that can be formed and the fabric layer that can be changed in thickness can be passed through the needle The thorn is reached. Alternatively, composite materials suitable for molding can be made from a single layer of formable fabric and a layer of variable press fabric. A facing fabric layer may be applied to the outer surface of either the formable fabric layer or the variable press fabric layer. The cohesion between functional fabric layers can be enhanced by such mechanical methods as needling and / or by adhesion methods such as spray powder bonding, using liquid dispersions / solutions, flame bonding, and / or interposing an adhesive layer and its combined use . The following examples illustrate various structural embodiments of the invention and how the physical properties of the structure of the invention can be controlled by changing certain program parameters. In the following example, the first and second stiffer layers are produced by needling, that is, by first blending the selected fibers on a standard textile blending device, then carding the fibers into a nonwoven fabric, and then crossing it Laying a net to create a multi-layered layer of high bulkiness, which was then needled with a needle penetration of about 1,000 needles.
