Hammerhead™ Marine Composite Panels: structural foam core sandwich panels Polystrand™ Thermoplastic Composite Panels: honeycomb core sandwich panels GlasArmor™ Ballistic Resistant panels 

Honeycomb panels are made from polypropylene, making it easier to avoid compromising the core during thermal lamination. Simply Supported Beam Deflection Hammerhead panel core density at various panel thicknesses Hammerhead™ PETG Laminate Hammerhead™ PETG Laminate * To calculate deflection for different panel widths, use the following formula: Deflection = Chart value* [12 / panel width]. Example: Deflection for 24 inch panel = Chart value *[12 / 24] Fixed End Beam Deflection - Metric 115 kg/m3 core density at various panel thicknesses Hammerhead™ PETG Laminate Hammerhead™ PETG Laminate * To calculate deflection for different panel widths, use the following formula: Deflection = Chart value* [12 / panel width].

CRTM™ (continuous resin transfer molding) panels are high quality composite sandwich panels with tailored, multi-axial fiber reinforcements, high-fiber volume contents and very low void content. CRTM panels are specifically designed for applications needing a high stiffness-to-weight ratio. Panel Thickness (in)

POLYSTRAND™ THERMOPLASTIC COMPOSITES Tapes, Laminates & Panels Polystrand™ high performance composite tapes and laminates are made by combining thermoplastic polymers and continuous fibers to create continuous fiber reinforced thermoplastic (CFRTP) composites. Polystrand composite panels are made with continuous fiber reinforced thermoplastic face sheets thermally bonded or adhered to traditional core materials such as honeycomb, foam, aluminum, and nonwovens as reinforcement. Standard and custom tapes, laminates, and panels are available in a variety of combinations of matrix resin systems including PP, PE, PETG, aPET, and PA6, and include fiber reinforcements such as E-Glass and S-Glass.
