PFC |
Perforated |
3 mm perforations in diamond pattern with 100/50 mm spacing. |
Secures core bonding to laminate in bagging operations with core-bonding adhesive or wet bagging. |
For infusion, PF20 is recommended to ensure good wet-out. |
 |
PF20 |
Perforated |
2 mm perforations in square pattern with 20 mm spacing. |
Ensures proper core bonding in vacuum-assisted processes such as infusion. |
Most common perforation option for prepreg or infusion. |
 |
GRC4 |
Grooved |
2×2 mm grooves in width and/or length direction, c/c 20 mm, on one or two sides. |
Fast, reliable resin distribution in vacuum-assisted processes. |
Best for larger panels and core thickness above 20 mm. Not recommended where very high surface finish is required. |
 |
GRC6 |
Grooved |
2×2 mm grooves c/c 20 mm along the sheet on two sides. |
Fast, reliable resin distribution in vacuum-assisted processes. |
Suited to large areas and thicker cores; avoid where ultra-high surface finish is needed. |
 |
GRC8 |
Grooved |
2×2 mm grooves c/c 20 mm across the sheet on two sides. |
Fast, reliable resin distribution in vacuum-assisted processes. |
Ideal for large panels and core thickness above 20 mm; not for very high finish surfaces. |
 |
GPC1 |
Grooved & Perforated |
2×2 mm grooves c/c 20 mm in both directions on one side with 2 mm perforations in the grooves. |
Very fast, reliable resin distribution in vacuum-assisted processes. |
Perforations transfer resin & wet out mould-side laminate. Reduced print-through thanks to small perforations. |
 |
GPC2 |
Grooved & Perforated |
2×2 mm grooves c/c 20 mm in both directions on both sides with 2 mm perforations in the grooves. |
Very fast, reliable resin distribution in vacuum-assisted processes. |
Perforations transfer resin to both skins. Not recommended where very high surface finish is required. |
 |
GPC8 |
Grooved & Perforated |
2×2 mm grooves c/c 20 mm along the sheet on two sides with 2 mm perforations in the grooves. |
Fast, reliable resin distribution in vacuum-assisted processes. |
Perforations transfer resin & wet out mould-side laminate; not for ultra-high surface finish. |
 |
GPL1 |
Grooved & Perforated |
1×2 mm grooves c/c 20 mm in both directions on one side with 2 mm perforations in a 40/20 mm diamond pattern. |
Reliable resin distribution on slightly curved surfaces. |
Optimised version of GPC1 to minimise resin consumption & weight while maintaining wet-out. |
 |
GS30 |
Cuts with Scrim |
Grid-scored 30×30 mm with 0.9 mm cuts, scrim backed. |
Allows the core to easily conform to mould surfaces in most applications. |
Scrim up or down depending on process (typically scrim down in hand lay-up/infusion; scrim up with core-bonding adhesive). |
 |
OD30 |
Cuts with Scrim |
0.9 mm cuts in length direction, c/c 30 mm, scrim backed. |
For single-curvature surfaces. |
Used where curvature is mainly in one direction. |
 |
DC30 |
Cuts |
Grid-scored in two directions on both sides with cuts to 55% of core thickness, no scrim. |
For slightly curved areas. |
Semi-flexible without scrim backing. |
 |
Q100 |
Cuts, Grooves & Perforations |
GS30 scrim-backed grid scoring with 2×2 mm GPC1 grooves and 2 mm perforations in the grooves. |
Very fast, reliable resin distribution & laminate wet-out in infusion on curved areas. |
Reduced print-through risk due to small perforations on mould side. |
 |
Q103 |
Cuts, Grooves & Perforations |
GW30 scrim-backed grid scoring with 2×2 mm GPC1 grooves and 2 mm perforations in the grooves. |
Very fast, reliable resin distribution & laminate wet-out in curved-area infusion. |
Wider cuts used where density or thickness requires it. |
 |
Q300 |
Cuts & Perforations |
GS30 scrim-backed grid scoring with 2 mm PF20 perforations. |
Fast, reliable resin distribution in vacuum-assisted processes for curved areas. |
Reduced print-through due to small perforations on mould side. |
 |
PSC |
Plain Sheet |
Plain core sheet without finishing. |
Used where no integrated flow or form feature is required. |
Typically used with external flow media or simple hand lay-up. |
 |
T |
Sanded |
Sanded surfaces for thickness tolerance of approx. ±0.25 mm. |
Improves thickness control & readiness for bonding. |
Used where a practical balance of tolerance, cost & speed is required. |
