Definitions

  • Composite comprising two or more superimposed layers of a wood-like material
  • the invention relates to a composite comprising two or more superimposed layers of a wood-like material, a use of the composite material as well as container or trailer floors formed from the composite material.
  • a composite material which in particular has two layers, which are connected to a non-foamed polyurethane binder based on a urethane-modified isocyanate.
  • the layers of the composite material may be lignocellulosic layers, in particular cork, wood, grass or straw.
  • bamboo layer materials produced from adhesives may have a relatively high density, from 0.8 to 1.0 kg / l or even> 1 kg / l.
  • the disadvantage is the inadequate static and in particular their insufficient dynamic performance Early fracture failure under static load (Institute of International Container Lessors (NLC), Technical Bulletin (TB) 001, September 1, 2002, Short Span Test), and especially delamination of the individual with phenol-formaldehyde and / or polyvinyl acetate bonded layers of layered materials produced therefrom.
  • NLC International Container Lessors
  • TB Technical Bulletin
  • Such, bonded with phenol formaldehyde coating materials also show their insufficient performance, especially at elevated temperatures (for example, at 80 0 C), which may well occur under corresponding climatic regions inside containers.
  • a composite material comprising two or more superimposed layers of a wood-like material, wherein the layers are interconnected with a one-component polyurethane adhesive containing a prepolymer having free NCO groups, wherein the wood-like material is a monocot.
  • Monocotyledons differ from the dicotyledons (dicotyledonous plants) in that they have no secondary growth in thickness because their vascular bundles lack cambium.
  • the monocotolydone is preferably a woody giant grass.
  • Woody Giant Grasses belong to the grass family (Gramineae), and have woody, annually elongated stems.

  • bamboo is generally understood to mean tree or shrub-like grasses with a long-lasting, woody or branched trunk.
  • the lignifying cell structure of the bamboo fabric and its technical properties are the same
  • the actual wood weave is quite similar, but there are also significant differences.
  • the bamboo is an extreme product of nature in size, lightness and strength. Its structure and characteristics are the same as those of a state-of-the-art high-tech material: it is stable but thanks to its cavities extremely light and elastic, it is stiffened by the partitions and has physical properties that are in part superior to those of other materials such as wood, concrete or steel. While wood has a hard core and softens to the outside, bamboo is hard on the outside and soft on the inside - a much more stable construction.
  • the "Guadua angustifolia" described by Humboldt and Kunt grows up to 1800 m above sea level in two subspecies called Guadua Macana and Guadua Castilla mostly in small groves along the streams, but also on meadows or slopes, reaching a height of about 20 to 25 m and a diameter of up to 18 cm, whereby each stem grows out of a net-like root system, reaches its full height in one year and lasts for 6 to 8 years until the conducting vessels become clogged.
  • the tube wall cross section through a bamboo internode shows a decorative pattern comprising fibers of the vascular bundle (vascular bundle) and fibers of the base tissue. From the inside to the outside, the vascular bundles pile up continuously. The more tear-resistant fiber strands of the vascular bundles lie closest to where the static stress is greatest, in the edge zone, similar to the steel reinforcement in reinforced concrete construction.
  • the bamboo cane is a prime example of a bionic solution, that is, a technical problem solving in nature.
  • the bamboo shows a clever lightweight construction: in the outermost silicified surface layer run axially parallel highly elastic fibers, with a tensile strength of up to 40 kN / cm 2 , which exceeds the tensile strength of mild steel (37 kN / cm 2 ).
  • the bamboo fabric has no radial fiber path like the medullary rays of the dicotyledons and also no cambium, which is why a growth in thickness above the ground does not occur. From the mechanics we know that with the same proportion of material a cylindrical tube has four times the bending stiffness compared to a full round rod, so the primitive plants are extinct and have only one reinforcing axis along the axis Fabric strand as a reinforcement.
  • a stalk or stem not only has a static purpose, but it also functions as a complicated organ. It transports water and nutrients from the root into the furthest tips of the leaves, and from there back to organic roots.

  • the cellulose has the most important part. By combining with other molecules (lignin), the cell walls can be stiffened differentiated.
  • the cellulose and part of the hemicellulose serve as builder, the lignin as binding and filler.
  • the cellulose content determines the buckling and tensile strength, the lignin content the compressive strength of a fabric.
  • the cell bundles we call fibers.

Conversely, the bamboo parts of a workpiece can be diagnosed microscopically by their physiognomic characteristics, determine the bamboo species concerned and into the cross-sectional zone they come from, rearrange.

  • bamboo Tensile Strength The bamboo outer wall is significantly more tensile than the inner skin, and slender tubes are superior to thicker tubes in relation to cross-sectional area. These results also explain the greater flexural strength of thin tubes versus thick ones; with thick pipes, the areal proportion of the outer skin fibers, which have a higher tensile strength, is less on the overall cross section.
  • bamboo material from the upper half of the third has a tensile strength about 12% lower than that of from the base of the stem. Nodienstellen have a strength-reducing effect on the tensile stress.
  • Slender bamboo tubes or rods thereof from the tube wall have thicker materials compared to higher strength values in relation to the cross-sectional area.
  • the accumulation of high-strength fiber strands in the outer wall zone have the same elasticity as tensile, shear or bending stresses.
