DragonPlate's carbon fiber LAST-A-FOAM® core utilizes FR-3706 foam. FR-3700 is a CFC-free, rigid, closed-cell, polyurethane foam with a density of 6 pounds per cubic foot. It exhibits a high strength-to-weight ratio due to its cellular structure and cross-linked resin. Because of its closed-cell structure, LAST-A-FOAMÂ® FR-3706 has great resistance to water absorption, and will not swell, crack, or split on exposure to water. For foam specifications, please refer to the official LAST-A-FOAM® FR-3706 technical data sheet. Also available is the FR-3700 product data sheet.
The carbon fiber skins comprise 0/90 degree uni-directional with twill weave face sheets. Carbon fiber skin thickness is approximately 0.03 inches on each side of the foam core, adding approximately 0.06 inches (1.5mm) to the core thickness.
This sheet size has a smooth satin finish on both sides, with options for the face sheet on both sides. Also available in this sheet size is the option for higher modulus uni-directional fabrics.
Since ultra-high modulus (UHM) carbon fiber material has certain export restrictions, customers are required to fill out a short form detailing the end use. Both the customer and application will need to be vetted before the product is able to ship. Please fill-out the PDF form and fax or email it back to us if you have ordered the UHM option.
