Problems solved by technology

The Applicant has observed that the manufacture of molded objects according to the teaching of this document is particularly cumbersome, since it is necessary to precisely control the position of the anisotropic regions and this position can be altered due to the flow of the flakes, thus jeopardizing the attainment of the desired mechanical characteristics Ability

Embodiment Construction

[0109] figure 1 A sheet molding compound 1 according to the invention is shown.

[0110] exist figure 1 In the illustrated embodiment, the sheet molding compound 1 is in the form of discrete sheets having a length L and a width W. As shown in FIG. However, sheet molding compounds in the form of continuous belts are also within the scope of the present invention. Also, the dimensions of width W and length L are average dimensions because, as will be better understood hereinafter, the edges of the sheet molding compound are not clean edges unless they are cut.

[0111] Although the sheet molding compound 1 has a finite thickness T, this thickness T is of insignificant dimensions compared to the dimensions of the width W and the length L, so reference will be made briefly hereinafter to the plane P of the sheet molding compound 1, the plane P refers to the geometric plane defined by width W and length L. For example, the thickness T can be between 0.5 and 5 mm, and the width ...

Abstract

A sheet compound (1) is disclosed, comprising a first group of conglomerates (3) of fibre segments (5) and a matrix (6) of polymeric material, the conglomerates (3) of the first group having a random orientation, and at least one second group of conglomerates (4) of fibre segments (5) and a matrix (6) of polymeric material, the conglomerates (4) of the second group having a prevailing orientation of a direction of maximum tensile strength (FR) thereof along a respective predetermined direction (FB) in said geometric plane (P), said at least one second group of conglomerates (4) being distinguishable from the first group of conglomerates (3) by at least one characteristic other than orientation. A process and an installation for making such a material, as well as a moulded object made from such a material are also disclosed.

Description

technical field [0001] The present invention relates to the field of sheet materials. Such materials are commonly referred to in the art as sheet molding compounds (Sheet Molding Compounds). [0002] While this term may have a more restrictive definition, in this specification and the appended claims, by "sheet molding compound" is intended to mean broadly a material that is more compact in one dimension than the other two Much smaller in size, comprising reinforcing fibers having modified properties as better specified hereinafter and at least one matrix of polymeric material as better specified hereinafter. In other words, the above expressions should neither be construed in a limiting sense to include specific fibers, specific matrix resins, nor necessarily require or conversely exclude fillers such as resins, binders and other additive fillers or have different components The presence of supports or layers. Background technique [0003] Molding compounds are known and...
