Abstract: Motor-vehicle body part including a lenticular sheet made of transparent molded plastic material of a given refractive index (n) higher than 1 and a given thickness (e), includes an external face forming an array of substantially spherical microlenses of a given radius of curvature (R), said microlenses being arranged with a given pitch and, an internal face of the lenticular sheet, which bears an array of three-dimensional features that are arranged with the pitch of the array of microlenses. This array of features is formed from fractions of a whole three-dimensional feature of equal dimensions, two adjacent fractions of three-dimensional features being offset in the direction in question by a given phase shift, each of these fractions of three-dimensional features magnified by a given coefficient of magnification, are juxtaposed on the internal face of the lenticular sheet with a pitch corresponding to the pitch of the microlenses.

Abstract: The present disclosure concerns a motor vehicle bodywork panel, including: a main body, a wall made of a plastic material that is transparent to a visible light, comprising a face visible from an outside of a vehicle, and a coating that is transparent to visible light, wherein the coating covers at least the face visible from the outside of the vehicle of the wall that is transparent to the visible light and visible from the outside of the vehicle, wherein the wall is encapsulated in a sealed manner between the main body and the coating that is transparent to the visible light.

Abstract: A method for manufacturing an element for a bodywork part successively including the steps of producing a support element having a first face on which a support sheet is fixed having at least one connection member, arranging a heating track on the support element, the heating track being arranged on the first face of the support element, connecting the heating track to the connection member, and arranging the support element in a molding chamber of a mold defining the shape of the element for a bodywork part, the first face of the support element facing the inside of the molding chamber, and injecting a plastic material into the molding chamber in order to cover the heating track.

Abstract: A system for preforming a sheet of plastic material (MP) including a first element forming a preforming cavity, the system including a second element adapted to be positioned opposite the first element, a set of pressing means sequentially actuated and carried by the second element to apply pressure locally to the sheet of plastic material (MP), so as to press this sheet (MP) against the first element, at least one means for sequential actuation of the pressing means.

Abstract: Method for preforming a plastic semi-finished product, wherein: at least one anti-adhesive membrane is positioned facing a wall of a preforming mould; the plastic semi-finished product is positioned facing the anti-adhesive membrane so that the anti-adhesive membrane is positioned between the semi-finished product and the wall; pressure is applied to press the semi-finished product against the wall of the preforming mould, in order to give a shape to the semi-finished product; pressure is removed and the preformed part is ejected from the wall; and the preformed part is removed from the mould.
