A low-density honeycomb core is used as the core of a sandwich structure.Honeycomb core has been used in a wide range of different areas depending on performance and price. The corresponding honeycomb core Machine to produce honeycomb core is also widely used. This article will show you why we should use honeycomb core Machine.
The following knowledge points are listed below:
Material of honeycomb core
Honeycomb core classification
Why we should use honeycomb core ?
Honeycomb core can be made from more than 500 different materials. The main honeycomb core materials are aluminum alloy, resin impregnated glass fiber fabric, aromatic fiber paper, kraft paper, graphite fiber and kevlar fiber. The resin content is about 50%.Honeycomb core hole has many different shapes, such as hexagon, rectangle, reinforced shape, etc.Its performance depends on the material, pore shape and size, etc., anisotropy, regular hexagonal honeycomb core material along the direction of L shear strength is about twice the direction of W.Mainly used for aircraft radome, radome, aircraft floor, rudder, etc.
Honeycomb core material has metal honeycomb core material and non - metal honeycomb core material two categories.Metal honeycomb core material is mainly aluminum alloy honeycomb core material.Non-metallic honeycomb core material has glass cloth honeycomb core material, paper honeycomb core material and Nomex honeycomb core material.Because of its low performance, the paper honeycomb core material is not used in aircraft structure.
The hole shape of honeycomb core material is mainly hexagonal, and there are also honeycomb core materials that have been stretched, and the hole shape is rectangular. In practical application, most of them are hexagonal honeycomb core material, and the over-stretched honeycomb core material is mainly used in sandwich structure parts with single surface.
(1) honeycomb core compared with other various sheet structure light, less material, low cost. Honeycomb core has the maximum strength/mass ratio, and thus the performance/price ratio of the finished product is good, which is the key to the success of honeycomb paper.
(2) honeycomb core has high strength, surface flat, approximately isotropic, good structural stability, not easy to deformation.honeycomb core’s outstanding ability to resist pressure and bending is the most important characteristics of box packaging materials.
(3) honeycomb core has impact resistance, good buffer.Honeycomb core is made of flexible paper core and surface paper, with good toughness and resilience, unique honeycomb sandwich structure provides excellent buffer performance, in all the buffer materials have a higher unit volume of energy absorption value, high thickness of honeycomb paper can replace a large number of used EPS plastic foam cushion.
(4) honeycomb core has sound absorption, heat insulation.Honeycomb core is a closed chamber filled with air, so it has a good sound insulation performance.
(5) honeycomb core after the recovery easier to deal with, recovery processing process simple, save a lot of costs, but also improve the utilization efficiency.
