Description

ACP’s Fiberglass Fiber/Foam Sandwich Panels are ideal panels for a wide range of applications requiring flat, lightweight and rigid specifications. They are manufactured by ‘sandwiching’ a 6 PCF polyurethane foam from LAST-A-FOAM between layers of self-adhesive fiberglass prepreg. Our sandwich panels are cured with high temperature and under pressure resulting in fully consolidated fiberglass skins that are completely bonded to the foam core. By separating the fiberglass skin with an foam core, these sandwich panels offer greater strength properties than those of the skins alone.

Using fiberglass prepreg for the outer layers creates structural skins that offer high strength, moderate tensile strength and compressive strength, dimensional stability, design flexibility and excellent electrical resistivity.

Manufactured with a with lightweight, high density structural foam, our foam core sandwich panels demonstrate the light weight, high strength and stiffness properties desired in a foam core panel and are lighter than balsa core panels. By using a structural foam, these panels feature higher compressive strength and crushing resistance than panels manufactured with a non-structural foam core. The LAST-A-FOAM® is a flame-retardant polyurethane (PU) foam and has great resistance to water absorption, and will not swell, crack, or split on exposure to water. This series is non-abrasive and can be machined with standard high-speed steel (HSS) cutting tools. They remain a more economical option and are ideal for applications that require low water absorption and good sound and thermal insulation.

Tips
  • If delamination occurs skins may be re-bonded using any structural adhesive, such as slow set cyanoacrylate (CA) glue or 5 minute epoxy adhesive.
  • Sandwich panels can be cut with a cut off wheel or a Tungsten Carbide Saber Saw. Do not cut with a band saw.
Resources
  • For specialized panel inserts, fasteners and latches contact The Young Engineers. As an industry-leading designer and manufacturer of hardware, their primary focus is on fasteners for honeycomb panels and composite materials.
