Embodiment Construction

[0040] Based on the above, the present invention relates to a method for obtaining foamed layer products based on a homogeneous mixture of at least one polyolefin and additives incorporating fiber reinforcement, all these components forming an integral part of the foamed layer product.

[0041] Before starting to describe the steps constituting the method for obtaining the foamed laminar product (6), the components (1) making up the above laminar product (6) are: polyolefin, additives and fibrous reinforcement.

[0042] Polyolefin (1.1) is the main constituent of the layer product, ie forms the basis of the mixture of component (1).

[0043] The polyolefin (1.1) can be, for example, polyethylene or polypropylene or a mixture of the two aforementioned polymers.

[0044] The second component which forms the ply and which is also the main cause of the stiffness of the ply is the fiber reinforcement (1.2).

[0045] Fiber reinforcement (1.2) is used as a loading for the mixture of...

Abstract

The invention comprises a method for manufacturing a foamed laminar product wherein the foam is obtained using thermoplastic material and additives. With a view to improving the rigidity of the foamed laminar product, reinforcing fibre is added to the mixture formed by the thermoplastic material and additives, such that the reinforcing fibre forms an integral part of the foamed sheet.

Description

technical field [0001] The present invention relates to a method for the manufacture of a foamed laminar product, wherein the foam is made of thermoplastic material and additives. [0002] The invention relates in particular to a method for obtaining foamed laminar products with improved hardness properties. [0003] For this purpose, the invention describes a method for obtaining foamed ply products based on a mixture of thermoplastic materials, additives and fibrous reinforcements, the reinforcing fiber material being an integral part of the foamed ply product. Background technique [0004] Foam is a material that includes small air cells distributed in a mass of material, and they have a lower density as a structure than the substrate. Foams can be obtained from thermoplastic, refractory or elastomeric materials. [0005] In particular, in the group comprising thermoplastic foams, they may or may not be reticulated. [0006] Non-reticulated thermoplastic foams can be o...
