Core Materials Forms of Supply

Core is supplied in a wide range of product forms, optimized for different applications and composite production processes. The standard product forms are described below. SP-High Modulus can also tailor sheets to your own specification - please call us to discuss your requirements.

PL - Plain Sheet – Optimum material properties. Limited bending in-mould.
PH - Plain with Bleeder Holes – Assists air release in vacuum bag processes.

CUTS FOR CONFORMABILITY (Foam)

SC – Single Cut – Provides flexibility in a single direction on one or both sides of a sheet. If done on both sides, the cuts intersect so no bleeder holes are necessary for vaccum bagging. Maximum sheet size is half of a full-size sheet.

DC - Double Cut – Provides flexibility in two directions on one or both sides of the sheet. If Double Cut on both sides, the intersecting cuts make DC a highly effective resin infusion medium. The cuts are not visible when the sheets lie flat and these narrow knife-cuts minimize unnecessary resin accumulations compared to sawn core materials.

CS – Contour Scrim – provides optimum flexibility in two directions. Sheets are knife cut in squares and bonded to a glass scrim. Available on sheets up to 25mm (0.98”) thick. Maximum standard sheet size is half the full sheet.

Surface grooves for infusion – Available on all foam types

VIC - Vacuum Infusion Core – Tailor made vacuum infusion materials are used by leading boatbuilders worldwide. There are several VIC options and we can customize grooving patterns and bleeder holes as required. For curved laminate sections, double-sided DC is very effective system for resin infusion with low weight gain. Heat forming VIC surface cut also useful for obtaining curved panels with minimal resin uptake.

PRODUCT FORMATS (Balsa)
Balsaflex® is available plain or with typical formats including perforations, microgrooves, with or without scrim, contour scrim and with optional coating.

OTHER PRODUCT FORMATS
Bead and Cove - Bead and cove strip planking aids the building of large, curved structures, in a mouldless build method.

Fillet strips – Triangular edge strips to create tapered panel edge drop-offs, or stringer base fillets.

Kits – SP-High Modulus has an extensive kitting capability to provide all the formats described here in customized, numbered, ready to use, CNC machined kits.
