METHOD OF PRODUCING A PANEL AND A CORE THEREFOR

FIBERCORE IP B.V., Rotte...

1. A method of producing a panel, the method comprising:
placing an assembly on a mold, the assembly comprising
core elements, the core elements each having
a first groove extending transversely to an injection line extending across the mold, the first groove extending in a first
surface of the core element, and

side wall grooves provided in side walls that extend in a direction parallel to the first groove,
the first groove and the side wall grooves all being separated from one another, and
impregnatable material webs extending along and between the core elements,
the assembly including a first side and a second side situated opposite the first side;
enclosing the assembly under a cover layer by sealing, the assembly being enclosed under the cover layer in relation to the
position of the mold;

introducing at least one inlet for injection material, the inlet ending at the first side of the assembly;
connecting the space, enclosed by the cover layer and the mold, to a discharge;
injecting the injection material via the inlet on the first side of the assembly and causing the injection material to move
along via paths formed by the material webs between the core elements;

causing the injection material to flow laterally from the first groove situated in the first surface via the material of the
material webs as far as into the side wall grooves; and

discharging air and/or gas from the enclosed space via the discharge by underpressure at a position which is at a different
level in relation to the position at which the inlet ends.

METHOD FOR PRODUCING SANDWICH PANEL

FiberCore IP B.V., Rotte...

1. A method for producing a panel having first and second panel surfaces that are mutually averted, the method comprising:providing a core element;
arranging a strip of impregnable flexible material along the core element, such that the strip defines a first lateral portion over a top face of the core element, a medial portion along a side face of the core element, and a second lateral portion extending beyond the core element transversely to a longitudinal direction thereof;
repeating at least twice each of:
providing a following core element alongside a preceding core element and on a preceding second lateral portion of a preceding strip of impregnable flexible material, and
arranging a following strip of impregnable flexible material along the following core element, such that the following strip defines a following first lateral portion over a top face of the following core element as well as over a preceding first lateral portion of the preceding strip, a following medial portion along a side face of the following core element, and a following second lateral portion extending beyond the following core element transversely to a longitudinal direction thereof;
thereby forming a series of parallel core elements and strips of impregnable flexible material that include medial portions located between two respective neighboring core elements, first lateral portions extending one above the other over multiple core elements and along the first panel surface, and second lateral portions extending one above the other over multiple core elements and along the second panel surface;
impregnating the strips of impregnable flexible material with a hardenable fluid; and
hardening the impregnated strips of material, to form the panel.

COMPOSITE BRIDGE DECK AND BRIDGE CONSTRUCTION

FiberCore IP B.V., Rotte...

1. A bridge deck comprisinga composite panel with a top plastic skin, a bottom plastic skin, and a core arranged between and attached to the plastic skins, and
an edge beam extending along an edge of the composite panel,
wherein the top plastic skin has a protruding part which protrudes laterally relative to both the core and the bottom plastic skin,
wherein the protruding part of the top plastic skin extends over and is attached to a top side of the edge beam, and wherein both the core and the lower plastic skin extend laterally up to a front side of the edge beam.

METHOD OF PRODUCING A PANEL AND A CORE THEREFOR

FiberCore IP B.V., Rotte...

1. A core element, having the shape of a block with a first surface, a second surface situated opposite the first surface, mutually facing longitudinal side faces, and mutually facing transverse side faces,wherein the first surface is provided with a first groove that is a continuous groove which extends parallel to the longitudinal side faces, wherein the first surface is further provided with a recess that extends through the core element and ends up in both the longitudinal side faces, wherein the first groove discharges into said recess,
and wherein the longitudinal side faces are provided with side wall grooves, the side wall grooves being continuous side wall grooves which extend between and end at the first surface and the second surface, and which are separated from and do not discharge into the first groove in the first surface.

METHOD FOR FORMING OF A TUBULAR SEMI-FINISHED PRODUCT FROM FIBRE-REINFORCED PLASTIC MATERIAL

FiberCore IP B.V., Rotte...

1. A method for producing a profiled semi-finished plastic product from web material, comprising:providing a plurality of webs of material;
continuously and simultaneously feeding the plurality of webs of material to and along a plurality of shaping pieces arranged next to each other, having a greatest transverse dimension which is smaller than a width of the plurality of webs of material;
folding each of the plurality of webs of material around a shaping piece to form a body and an edge strip which projects transversely with respect to the body;
causing the edge strip of each of the plurality of webs of material to at least partly cover each other;
impregnating the plurality of webs of material with folded-over edge strips covering each other with a hardenable means;
causing the hardenable means to harden to form a profiled semi-finished plastic product, in such a manner that hollow or open spaces remain, each defined between two neighbouring bodies and edge strips in the profiled semi-finished plastic product.
