CarbonCore’s SphereCel SBF is a pre-compressed, stitch-bonded glass fiber material which is volumized by embedding thermoplastic microspheres and fiberglass fiber .
As a true all fiberglass core material, this product is particularly suitable for wet-on-wet process for producing both stable and light homogeneous laminates at the same time. The excellent characteristics result from the complete impregnation with ca. 40% by volume of the same resin used to laminate the skin layers. This sandwich material which can be laminated substitutes balsa, PVC foam material and other core materials but has the advantage of being able to adjust to the mold three-dimensionally. During the impregnation stage, SphereCel SBF can be formed into bevels, localized depressions or multiple pieces can by joined to form a void and split free part, eliminating the need for beveled edge strips. Multiple layers of material can be stacked to produce thicker laminates.
This product is available in 6 mm,8 mm,10 mm and 12 mm thicknesses.
