Product Data Sheet bCores QX summer bCoresQX summer Product description bCores QX summer is a structural core suitable for composite applications. The core is made of balsa plywood orientated in 4 different directions (quadri-axial), which significantly improves mechanical properties, especially shear properties in length direction. The balsa plywood ensures an exceptionally high compression strength and stiffness with good bending properties of the core. Core construction Wood type: FSC certified BANOVA balsa plywood Dimensions L: 1530 x 15 x 450 mm M: 1530 x 15 x 300 mm Density of 210 kg/m3 Machining guidelines • QX cores can be processed with high-speed wood working machine. • Best results for shaping QX cores are obtained with belt sanding machine. • For contour milling, climb milling has to be preferred to conventional milling. • After machining, cutting dust has to be carefully removed with vacuum cleaning equipment. Mechanical mean properties on the core width x direction is length direction parallel to ribs y direction is width direction z direction is out of plane direction * All these values are average values for the complete core. As the high-density balsa is mainly on the sides, it is mostly removed in the center of the ski when the sidecut is machined. Thus the actual density of the core in final shape will be in the range between 200-205 kg/m3.

Ecological aspects Balsa is the fastest growing tree in the world It is FSC-certified, compliant with FSC criteria, which include e.g. taking care of indigenous peoples' rights, maintain biodiversity, resources and landscapes Regarding water usage, CO2 footprint and embodied energy, balsa has an overall environmental impact about 40% lower than paulownia wood Product Data Sheet bCores QX summer Processing guidelines • The QX cores can be used with any classical manufacturing method (Contact molding (hand/spray), vacuum infusion, resin infusion / injection (VARTM / RTM), adhesive bonding, Pre-preg...
