RAWCELL® Fiber PGA550

Description of the product

PGA 550 is a sandwich panel without a cosmetic finish, with an aluminium honeycomb core and glass fibre fabric skins impregnated with epoxy resins directly by Starcell. Main fields of application: construction, furniture, naval, weight-reduction of marble and mosaics.

Layers

1) INTERNAL CORE aluminium honeycomb (Starcell production) aluminium alloy: 3000 series density: 29 - 50 - 56 - 65 - 80 kg/m³ cell diameter: 6.35 mm (standard); 10 - 12.7 - 19 mm (on request)

2) ADHESIVE thermosetting (Starcell formula) 3) EXTERNAL SKINS glass fabric impregnated with epoxy resins (impregnated fabric weight: 550 g/m² per side)

PROPERTIES
  • Excellent resistance to shear and bending forces.

  • Excellent dimensional stability, also in terms of flatness over time.

  • Very good compressive strength (due to aluminium honeycomb).

  • High mechanical performance, compared to the remarkable lightness of the panel.

  • Excellent weather resistance.

  • Wide operating temperature range.

  • Ease of machining with manual or CNC equipment.

FIELDS OF APPLICATION

Typical applications of the RAWCELL  FIBER – PGA 550 panel are in the marble, stone and ceramic markets; the panel is often used for civil engineering applications both indoors and outdoors (including application in ventilated façades); it is supplied in standard or custom sizes to suit all needs.

STORAGE

The RAWCELL  FIBER – PGA 550 panel is a product in the “semi-finished products” category and therefore is subject to further processing; we recommend storing the panels horizontally in a closed and dry environment, possibly away from heat sources and to support them along their edges.
