Jiaxing CMAG Composite Material Co., Ltd. is one of the most reliable manufacturers and suppliers of slotted aramid paper honeycomb core in China, specialized in providing high quality custom service. Welcome to wholesale high-grade slotted aramid paper honeycomb core made in China here from our factory.
Slotted aramid paper honeycomb core is a functional specialty honeycomb material developed on the basis of conventional aramid paper honeycomb core. While retaining the excellent inherent properties of aramid paper honeycomb-such as light weight, high strength, flame retardancy, temperature resistance, corrosion resistance, electromagnetic wave transparency, and sound absorption-the slotted structural design endows the material with effective ventilation and flow‑guidance capabilities. This gives it irreplaceable advantages in specific applications such as heat dissipation, airflow distribution, and weight reduction through guided flow.

Advantages and Characteristics:
Aramid paper honeycomb cores exhibit outstanding specific strength and specific stiffness, with the specific stiffness approximately nine times that of steel. While maintaining excellent rigidity, they significantly reduce structural weight-they are 50% lighter than aluminum honeycomb. When used in honeycomb composite structures, local weight reduction of about 20% can be achieved, along with improved fatigue resistance and extended service life.
Although slotted honeycomb cores show slightly lower compressive and shear properties compared to conventional honeycomb cores of the same density, their key mechanical properties still meet over 65% of the factory release test values specified in the standard for conventional aramid paper honeycomb cores.
Ventilation and flow guidance: The slotted structure enables unimpeded airflow, providing high ventilation efficiency.
The cores exhibit good compatibility with various resin systems, adhere well to skins made of a wide range of materials, and are suitable for diverse forming processes.
Compared with perforated honeycomb cores, slotted honeycomb cores feature simpler manufacturing processes, shorter lead times, and lower costs. They are easy to cut, bond, and mold, and can accommodate complex‑shaped structures.
Applications:
Leveraging its combined advantages of light weight, high strength, effective ventilation and flow guidance, flame retardancy, and temperature resistance, slotted aramid paper honeycomb cores have been widely adopted across multiple industries.
In the aerospace sector, they are used in aerodynamic components such as aircraft radomes, fairings, horizontal stabilizers, ailerons, and flaps. They are also employed in rocket fairings, satellite connection components, and spacecraft protective structures. The unique ventilation architecture of slotted honeycomb cores offers distinct advantages in applications requiring effective airflow, such as avionics bay cooling, radome ventilation, and fairing airflow guidance.
In the rail transit industry, these cores are widely utilized in ventilation openings for high‑speed train and rail vehicle cabins, air‑conditioning flow‑guide cores, and equipment bay cooling grilles.
Furthermore, slotted aramid paper honeycomb cores are also applicable in shipbuilding, industrial equipment, new energy, and other related fields.
