What Carbon-Core does

Carbon-Core Corporation (dba Carbon-Core Corp.) is a privately held specialty materials manufacturer founded in 2013 and headquartered in Spartanburg, South Carolina, with a manufacturing and engineering facility in Troy, Virginia. The company designs and produces structural core materials used in composite sandwich panel construction across marine, wind energy, transportation, industrial, architectural, and tub/shower applications. Its core technology, branded Dynamic Impact Resistance Technology, is an extruded, thermo-fused polypropylene honeycomb (not glued) that delivers ~200% elasticity, near-zero water absorption, sound/vibration damping, and chemical resistance; the company also offers CarbonBalsa (end-grain balsa), CarbonFoam structural foams (PIR/PU, PVC, fiber-reinforced), CarbonBond core bonding compounds, CarbonCore laminated panels, and ACT MAT/SphereCel laminate bulkers. Sandwich panels built with its cores are claimed to deliver roughly 7x flexural stiffness versus solid sheet at near-equal weight, and a 4x thickness increase yielding 37x stiffness at only 10% additional weight.

Carbon-Core monetizes through direct sales of its manufactured core materials via an online storefront and company sales team, supplemented by custom CNC-kitted packages for specific applications and a 100% refundable sample box to lower trial friction. Pricing is quote-based and not publicly disclosed. In April 2016 the company signed an exclusive North American distribution agreement with China's NMG Composites Co. Ltd., under which Carbon-Core represents NMG's fiberglass reinforcement product line in the US and Canada, with NMG warehousing from Virginia to cover 80% of the US within two days. Marketing is primarily through the company website, trade publications, trade shows, and partner referrals, targeting industrial SMB and enterprise customers in markets including the US, Canada, France, China, Brazil, and South Africa. The company is small (11-50 employees), privately held, and discloses no external funding or revenue.

Core offering

Carbon-Core Corporation manufactures and sells structural core materials — proprietary polypropylene plastic honeycomb, end-grain balsa wood, structural foams (PIR/PU, PVC, fiber-reinforced), bonding compounds, and laminated composite panels — used to build lightweight, impact-resistant sandwich panels for marine, transportation, wind energy, industrial, architectural, and tub & shower applications. Products are available as standard sheets, custom CNC-kitted packages, and finished laminated panels, sold directly through the company website, through an exclusive North American distributor (NMG Composites), and via direct enterprise sales.

Product overview

Carbon-Core Corporation offers a comprehensive portfolio of structural core materials for composite sandwich panel construction. The product lineup centers on five core technologies: CarbonCore Plastic Honeycomb (polypropylene-based thermoplastic honeycomb), CarbonBalsa (end-grain balsa wood core), CarbonFoam Structural Foam (PIR/PU, PVC, PET, and fiber-reinforced foams), CarbonBond bonding compounds, and CarbonCore Laminated Panels. These materials serve marine, wind energy, transportation, industrial, architectural, and tub/shower applications. The portfolio emphasizes weight reduction, impact resistance, sound damping, and thermal insulation properties achieved through sandwich construction techniques. Products are available as raw materials, pre-cut kits via CNC manufacturing, and finished laminated panels with optional gel coat surfaces and custom skin materials.
