Product Data Sheet bCores QX+ Ski Product description bCores® QX+ 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 fatigue and long-term shear properties in length direction. The sidewalls are reinforced with 320 kg/m3 dense Pachaco wood. The combination ensures the best weight to solidity ratio, with exceptionally high compression strength and stiffness, which guarantees good bending properties of the core. The patented bCores® QX+ construction delivers constant quality and density. Processing guidelines • The QX+ core can be used in any classical manufacturing method (contact molding (hand/spray), vacuum infusion, resin infusion / injection (VARTM / RTM), adhesive bonding, Pre-preg processing, compression molding (GMT, SMC)). • Compatible with most standard resins. • Processing temperatures up to 150°C and manufacturing pressure up to 15 bards can be used. • Please consider our process guidelines. Mechanical properties on the core width Density* 280 kg/m3 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 fern tree stands on the sides, it is mostly removed when the sidecut is machined. Once machined, a minimum hard wood side wall thickness of 10 mm will remain. Thus the actual density of the core in final shape will be in the range between 260270 ke/m3. Dimensions Standard widths: M_120 mm, L_140 mm Thickness: 2-1220 mm Maximum length: 3070 mm Standard lengths: 1530, 1800, 2000, 3070 mm Core construction Number of ± 45° shear web: Size M_3, Size L_4 Wood types: 72% BANOVA® balsa, 28% Pachaco wood.
