The main factors affecting the performance of aluminum honeycomb cores include aluminum foil, node glue and aluminum honeycomb core specifications, etc., the following is a specific analysis:

1. Aluminum foil

Aluminum foil is one of the main constituent materials of aluminum honeycomb core, and its performance directly affects the overall performance of aluminum honeycomb core. In the processing process of aluminum foil, the surface treatment should be strict. In products that require high strength or durability, aluminum honeycomb core materials made of pure aluminum foil should be used with caution.

2. Node glue

Nodal adhesives are used to join aluminum foils to form a honeycomb structure, and their properties are critical to the strength and stability of aluminum honeycomb cores. The joint adhesive should be epoxy modified high-temperature curing adhesive, which can not only provide sufficient bonding strength, but also have excellent environmental resistance and high and low temperature resistance. Due to the low strength of the aluminum honeycomb core, ordinary adhesives are prone to degumming, resulting in overall failure and instability. The joint strength data of aluminum honeycomb core should be ≥ 2.0N/mm, and its joint strength is the main basis for evaluating performance.

3. Specifications of aluminum honeycomb core

The specifications of the aluminum honeycomb core are determined by the thickness of the aluminum foil and the size of the honeycomb cell. Aluminum honeycombs with different specifications have different densities, and the manufacturing cost also varies greatly. The specifications of aluminum honeycomb cores can be expressed in two ways: the diameter of the inscribed circle of the honeycomb cell (in imperial units) and the thickness of the aluminum foil / the length of the side of the cell (in metric units), and the national standard in China is expressed in terms of the thickness of the aluminum foil / the length of the side of the battery.

In summary, aluminum foil, node glue and aluminum honeycomb core specifications are the main factors affecting the performance of aluminum honeycomb cores. In the production and application process of aluminum honeycomb core, these factors should be strictly controlled to ensure the performance and quality of aluminum honeycomb core.
