The internal structure of PMI foam is closed-cell, with a low thermal conductivity (0.02-0.04 W/(m · K)). Combined with the low thermal expansion coefficient of carbon fiber, the board has both heat insulation and heat preservation performance. Meanwhile, the foam core material can effectively absorb impact energy and has a better shock absorption effect than solid boards (such as when used in the shells of precision instruments and high-end sports equipment).

Aramid honeycomb with options of 29 - 144 kg/m³. Aramid honeycomb, with its comprehensive advantages of "lightweight, high strength, durability, and stability", is widely used in fields with strict performance requirements such as aerospace (fuselage structure, cabin doors), high - end rail transit (high - speed rail interiors), ships (lightweight decks), and new energy (wind turbine blades).

PP honeycomb sheet，70-80 kg /m³, pore size 6-8mm, low price

The thickness of the aluminum honeycomb can be customized from 2.7 to 80 millimeters. It is processed from 0.3 to 1.5 millimeters of carbon plate with skin, which is lighter in weight and a high-strength carbon fiber composite board

Carbon fiber tubes are tubular structural components made from carbon fiber composite materials through winding technology. Their characteristics stem from the high performance of carbon fiber and the structural advantages of its tubular form. The core features can be summarized as "strong, light, tough, and durable", etc
