3.1.15
neutral plane
plane internal to the ski where no bending stresses occur when the ski is bent perpendicular to its bottom surface
3.2 Terms relating to types of construction
Modern skis generally consist of composite structures. A composite structure, in the technical sense, is a type of construction in which different materials are combined in a single structural element such that every material performs optimally to an applied stress. Materials with high strength and stiffness are incorporated mainly in the external zone of the ski cross-section in order to sustain the bending and torsional stresses occurring in the ski. These structural members are called the load-carrying layers, because of their contribution to important properties of the ski, such as breaking strength and stiffness. A combination of different materials in the load-carrying layers is possible.
A ski may be classified according to the construction employed and the materials used in the load- carrying members of the ski. For an exact specification of constructional parameters, it is recommended that the ski elements and the materials employed be explicit.
EXAMPLE
— load-carrying layers: glass-fibre-reinforced plastic
— core: ash wood
— steel edge: cracked edge, hardness 45 HRC
— top edge: aluminium
side walls: phenolic material
running-surface material: sintered UHMW PE
— top-surface material: phenolic material
3.2.1
sandwich construction
composite structure in which the ski core is reinforced above and below with materials of higher strength and stiffness than the core itself
NOTE These reinforcing materials are generally distributed over the entire width and length of the ski. The ski core may be partly hollow and made from a variety of materials, such as wood or polyurethane.
3.2.2
box construction
composite structure in which the load-carrying members are built as a combination of webs and flanges arranged in box form following the external shape of the ski cross-section or partly in the interior of the ski
NOTE The ski core may be partly hollow and made from a variety of materials, such as wood or polyurethane.
3.2.3
wood ski
ski with wood core, not having load-carrying layers of higher strength and stiffness than wood, except the steel edge
3.2.4
metal ski
sandwich or box structure where the load-carrying layers are metal, normally aluminium alloy
NOTE The core material may be partly hollow and made from a variety of materials, such as wood or polyurethane.
3.2.5
fibreglass ski
sandwich or box construction where the loadcarrying facings (except the steel edges or metal top edges) are made from glass-fibre-reinforced plastics
NOTE The core material may be partly hollow and made from a variety of materials, such as wood or polyurethane.
