Product Data Shee t bCores QX+ Sb Product description bCores® QX+ SB 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 pachaco. 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+ SB construction delivers constant quality and density. Processing guidelines • The QX+ SB 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 15°C and manufacturing pressure up to 15 bards can be used. • Please consider our process guidelines. Mechanical properties on the core width Density* 260 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 20 mm will remain. Thus the actual density of the core in final shape will be in the range between 240250 kg/m3. Dimensions Standard widths: 320 mm Thickness: 2-1220 mm Maximum length: 3070 mm Standard lengths: 1530, 1800 mm Core construction Number of ± 45° shear web: 4 Wood types: 72% BANOVA® balsa, 28% Pachaco tree.

Product Data Sheet bCores QX+ Sb Ecological aspects Both balsa and pachaco are among the fastest growing trees in the world They are 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 and pachaco have an overall environmental impact about 40% lower than paulownia wood.
