Honeycomb cores utilize the paper and card pertaining to low strength and rigidity, low load applications (such as domestic internal doors) in order to high strength and stiffness, extremely lightweight components with regard to aircraft structures. Honeycombs is usually processed into both washboard and curved composite constructions, and can be made to conform to compound curves without having excessive mechanical force or even heating. Honeycomb cores can present stiff and very light laminates but due to their very small bonding area they're just almost exclusively used with high-performance resin systems like epoxies so that the mandatory adhesion to the laminate skins is usually achieved. Aluminum honeycomb produces one of many highest strength/weight ratios involving any structural material. There are various configurations of the adhesive bonding of this aluminum foil which can lead to a variety of geometric cellular shapes (usually hexagonal). Properties is usually controlled by varying the particular foil thickness and mobile size. The honeycomb is normally supplied in the unexpanded block form it is stretched out into the sheet on-site. https://www.china-honeycomb.com/Honeycomb-Core-pl6882776.html
