Definitions

  • the present invention is directed to a freight container comprising a floor, a roof and a plurality of walls that form, in use, a door wall, a front end wall and a plurality of side walls and optionally side end walls that extend in between the roof and the floor of the container, said container defining a length direction of the container extending parallel with the floor and the side walls, said container defining a height direction of the container extending parallel with the corner posts.
  • freight containers are preferably of a standard size, such as freight containers conforming to the ISO standards for containers.
  • An ISO (International Standards Organization) container is a freight or shipping container that complies with one or more relevant ISO container standards, such as the ISO 1496 series.
  • Types of freight containers may vary according to their application, but include nominal 20 and 40 foot ISO containers and 10, 25, 30, 45, 48 and 53 foot containers and SWAP bodies for conveyance of goods by road, rail and/or sea.
  • the containers of the present invention include general purpose, thermal (e.g. insulated, refrigerated, heated) or bulk containers as described in the ISO 1496 series, but also include non ISO containers and SWAP bodies.
  • the ISO container standards provide minimum structural properties relating to the strength of the walls, roof and floor. Rigidity and weatherproofing standards are also set. The standards ensure that the containers are suitable for purpose as freight, shipping or cargo containers. Freight containers must be able to withstand extremely high forces, such as for example resulting from stacking or from ship movement, under all kind of weathering conditions. For example, a fully loaded freight container must be apple to support a mass of containers (also referred to as stacking) without permanent deformation or abnormality which will render the container unsuitable for use and without sacrificing the dimensional requirements affecting handling, securing and interchange.
  • Posts are vertical frame components which are integral with the floor structure and castings (fittings) which provide means for lifting, handling, stacking and securing the container.
  • Corner posts are posts located at the corners of freight containers.
  • a front corner post is a corner post at the front end of the freight container, i.e. opposite the door end.
  • a rear corner post is a corner post at the door end of the freight container.
  • freight or shipping containers generally have used a metal framework with steel or aluminum sheathed panels attached to the framework by bolts, rivets or welding.
  • the problem with using such freight containers is that they are very heavy.
  • the heavier weight of these containers limits the maximum cargo weight, or payload, that can be transported in such a container due to limitation on maximum allowed gross weight by local regulations.
  • Freight containers comprising fibre reinforced composite materials, such as for example described in US7059488, could result in lower weight. This lighter weight will increase the amount of cargo that can be carried in the freight container.
  • Composite material structures have also been shown to be more resistant to corrosion, making the containers more suitable for use in marine and other hostile environments.
  • a freight container comprising a floor, a roof and a plurality of walls, said walls extending in between the roof and the floor of the container and comprising at least a front end wall, and a plurality of side walls, wherein said floor, said roof, and said walls each comprise at least one panel, each panel having two surface
  • the panels comprise a fibre-reinforced wall material comprising a first outer fibre layer and a second outer fibre layer, and at least a first intermediate fibre layer and a second intermediate fibre layer that are arranged in between the first and second outer fibre layers, wherein fibres of the first and second outer fibre layers are aligned along an outer fibre direction, and fibres of the first intermediate fibre layer and fibres of the second intermediate fibre layer are aligned respectively along a first intermediate fibre direction and a second intermediate fibre direction that are mutually transverse and are inclined with respect to the outer fibre direction, and wherein the outer fibre direction is aligned with a shortest of said surface dimensions of said panels.
  • Increasing the compressive strength and the flexural strength and/or flexural modulus of the fibre reinforced wall material results in an improved stiffness of a panel comprising the fibre reinforced wall material as claimed.
  • the compressive strength and the flexural strength and/or flexural modulus of the fibre reinforced wall material will be reduced.
  • the compressive strength and the flexural strength and/or flexural modulus for such another stacking sequence can be increased by applying a much higher amount of fibres, but this will result in an increase of the weight of the side wall an/or the roof and thus of the freight container.
  • the fibre-reinforced wall material further comprises multidirectional reinforcement layers, the multidirectional reinforcement layers comprising at least a first and second support fibre layer comprising fibres aligned along a support fibre direction, said first support fibre layer being present contiguous to said first outer layer, and said second support fibre layer being present contiguous to said second outer layer, and wherein said support fibre direction is transverse to said outer fibre direction.
  • the multidirectional reinforcement layers of the panel of the front end wall may be present on either side of the outer layers, i.e. as an additional reinforcement in the support fibre direction transverse to the outer fibre direction.
  • Weight reduction on one hand and strength and structural integrity on the other hand are the main design drivers for the container of the present invention.
  • the inventors advantageously found that without compromising the integrity of the freight container with respect to handling, loading, racking, and lifting thereof in use, the requirements for the composite wall panels may be released with respect to the side walls and roof of the containers, whereas this is not the case for the frond end wall of the container, which is to be designed such as to withstand multidirectional force and stress applied thereto.
  • the side walls and roof primarily require to withstand bending loads and stress - i.e. a sufficiently large flexural strength and flexural modulus, while requirements for other sources of stress (e.g. multidirectional stress, shear stress) may be released.
  • the fibre-reinforced wall material of the front end wall comprises additional fibre layers: multidirectional reinforcement layers; whereas at the same time such layers are not necessarily present in any of the other walls of the container.
  • the front end wall thus have a structure that is adapted not only to withstand flexural forces, but also multidirectional loads, thereby requiring a quasi-isotropic configuration with respect to its surface (fibres extending in eight directions (four alignments)).
  • this design enables to provide an optimum between total weight of the container on one hand, and structural integrity on the other hand.
  • the weight reduction achievable in properly designing the container according to this principle of accurate load analysis for each wall provides an important benefit over conventional composite containers.
  • the walls of the container further comprise one or more side end walls or roof end parts located adjacent and parallel to said side walls and roof respectively, at a far or tail end of said container, wherein each of said side end walls or roof end parts comprises at least one panel comprising said fibre-reinforced wall material, and wherein for panels of at least said side end walls or roof end parts the fibre-reinforced wall material comprises shear stress reinforcement layers, said shear stress reinforcement layers comprising at least a third and a fourth intermediate fibre layer arranged in between the first and second outer fibre layers, wherein fibres of the third intermediate fibre layer are aligned with the fibres of the first intermediate fibre layer and the second intermediate fibre layer is arranged in between the first and third intermediate fibre layers; and wherein fibres of the fourth intermediate fibre layer are aligned with the fibres of the second intermediate fibre layer and the first intermediate fibre layer is arranged in between the second and fourth intermediate fibre layers.
  • the weight of the container as a whole can be reduced considerably. This is an important improvement in the field of composite containers, as it will be appreciated by the skilled person that the total weight of a freight container is a main cost driver in the transportation industry. Moreover, the more weight reduction, the least energy there is required for handling, lifting or moving the container from A to B. Therefore, the light weight container of the invention also provides environmental advantages.
  • At least part of the roof and/or the side walls of the container comprises the fibre-reinforced wall material, wherein, in the roof and the side walls, the outer fibre direction is directed transverse to the length direction of the container.

  • the intermediate fibre directions are inclined with respect to the outer fibre direction. As used herein, this means that the angle between the intermediate fiber directions and the length direction is 45 ⁇ 20°, preferably 45 ⁇ 15°, more preferably 45 ⁇ 10°, even more preferably 45 ⁇ 5° and even more preferably 45°.
  • the angle between the outer fibre direction and the length direction is 90 0 and/or the angle between the outer fiber direction and the intermediate fiber directions is 45°. More preferably, the angle between the outer fibre direction and the length direction is 90 0 and the angle between the outer fiber direction and the intermediate fiber directions is 45°. This advantageously results in that the rigidity of the freight container is maximized.
  • At least part of the roof and/or the side walls of the container comprises, a laminate structure comprising an outer and an inner laminate layer formed, at least partly, by the fibre-reinforced wall material and the laminate structure further comprises a core layer arranged in between, and in mechanical contact with, both laminate layers, said core layer in use supporting the laminate layers, wherein, in said roof and side walls, the outer fibre direction is directed transverse to the length direction of the container (for the roof, the outer fibre direction is directed parallel to the width direction) and the inner laminate layer is located at the inner side of the container (where the freight is to be located) and the outer laminate layer is located at the outer side of the container.
  • the fibre-reinforced wall material of the at least one side wall and/or roof further comprises, at least, a third intermediate fibre layer and a fourth intermediate fibre layer arranged in between the first and second outer fibre layers, wherein fibres of the third intermediate fibre layer are aligned with the fibers of the first intermediate fibre layer and the second intermediate fibre layer is arranged in between the first and third intermediate fibre layers; and wherein fibres of the fourth intermediate fibre layer are aligned with the fibers of the second intermediate fibre layer and the first intermediate fibre layer is arranged in between the second and fourth intermediate fibre layers.
