Aramid Honeycomb Core

Aramid Honeycomb Core combines aramid fiber paper impregnated with flame-retardant phenolic resin to deliver lightweight structural performance in sandwich composites. The manufacturing process involves printing, stacking, thermal pressing, stretching, and dipping the aramid paper substrate in heat-resistant phenolic resin before curing and slicing.

The hexagonal cell structure maximizes material efficiency for space filling and load distribution. This geometric configuration provides exceptional strength-to-weight and stiffness-to-weight ratios while maintaining low density from 24 kg/m³ to 160 kg/m³. The core demonstrates excellent corrosion resistance, self-extinguishing flame properties, thermal stability, and superior dielectric performance.

Two cell variants accommodate different applications: regular hexagonal cells for maximum structural stability and over-expanded cells that bend easily in one direction for forming curves. Available cell sizes range from 3.2mm to 9.6mm, with standard sheet dimensions up to 2,440mm × 1,220mm. Compression strength spans 0.54 MPa to over 13 MPa depending on density.

Applications include aerospace components like aircraft galleys, flooring, and radomes; automotive racing car bodies; marine boat hulls; ground transportation panels; military shelters; and sports equipment where lightweight, high-strength cores with environmental resistance are essential.

    Frequently Asked Questions

    What is Aramid Honeycomb Core made from?

    Aramid honeycomb core is made of aramid paper impregnated with flame-retardant phenolic resin. Aramid is a high-performance polymer with excellent high temperature resistance, chemical corrosion resistance, and mechanical strength.

    What are the key characteristics of Aramid Honeycomb Core?

    Its characteristics include good resin penetration, high specific strength and stiffness, excellent corrosion resistance and self-extinguishing properties, better weather resistance and insulation, good electromagnetic wave penetration performance, and high stability.

    What types of cell structures are available?

    We offer aramid honeycomb cores in two cell types: regular hexagonal honeycomb core and over-expanded hexagonal honeycomb core. The regular hexagonal structure is more stable, while the over-expanded cell shape allows the panel to bend easily in one direction for forming simple curves.

    What are the typical applications for Aramid Honeycomb Core?

    It is widely used in aerospace, automotive, electronics, and protection fields. Specific applications include ship bulkhead connecting plates, helicopter rotor blades, fuel tanks, antennas, radars, floors, hulls, racing car bodies, and ground antennas.

    What are the available cell sizes and densities?

    Aramid honeycomb core is available in cell sizes such as 3.2mm, 4.0mm, 4.8mm, and 6.4mm, with densities ranging from 24 kg/m³ to 144 kg/m³. It features regular cell sizes, even density, and consistent color.

    What advantages does Aramid Honeycomb offer over aluminum honeycomb?

    Compared with aluminum honeycomb, aramid honeycomb has better bonding performance, corrosion resistance, and electromagnetic wave permeability. It also offers low thermal expansion, low thermal conductivity, high heat resistance, fire resistance, and dimensional stability under hot and humid conditions.

    Can Aramid Honeycomb Core be customized?

    Yes, it can be supplied in sheets, blocks, or cut-to-size pieces in both regular hexagonal and over-expanded cell configurations. Customizable options include material, cell structure, density, thickness, and grade, and value-added services like CNC machining, contouring, and potting are available.

    What level of supply reliability and customization can we expect for large-volume OEM production runs?

    We are a direct manufacturer with over 20 years of experience, producing 1500+ m² daily to ensure long-term supply stability. Our highly automated production lines can produce large-sized honeycomb blocks up to 2440mm in width, with consistent quality and even density. We offer customization in cell structure, density, thickness, and grade, and can provide materials in sheets, blocks, or cut-to-size pieces to meet precise OEM specifications for integration into final products like RVs, trucks, and boats.

    What kind of pricing structure and support is available for distributors and wholesalers purchasing in bulk?

    As a manufacturer serving clients globally, we offer favorable pricing for bulk orders and can supply standardized core materials in large sheet sizes. We provide reliable logistics support, including palletized packaging for freight shipment, and ensure high inventory turnover with our significant daily output. Our product is available with consistent physical and mechanical properties, making it ideal for resale to a network of businesses in applications ranging from construction to transportation.

    How does the material ensure ease and speed of installation for construction and contracting projects?

    The hexagonal cell structure provides high strength-to-weight ratio and exceptional stiffness, making the panels easy to handle and install. The material exhibits excellent dimensional stability and is very bondable, allowing for strong sandwich construction with various facings. It is corrosion resistant and offers good thermal insulation, contributing to durable and efficient project outcomes. We supply the core in formats suitable for construction, though on-site installation support is not provided as we focus on manufacturing and supply.
