3.2mm (1/8") Cell Aluminium Honeycomb

Unexpanded, unperforated aluminium honeycomb core material made from 5052 grade alloy. The honeycomb has a 76.9kg/m3 density and small 1/8" cells. This specification is typically used for the most high-spec applications including high-end motorsport/f1 and aerospace components, generally in conjunction with prepreg laminates and adhesive film.

Available in 10mm, 15mm and 20mm thicknesses in full sheet sizes of 2500mm x 1250mm or quarter sheets of 1250mm x 652mm.

High performance aluminium honeycomb core exactly as supplied to the world's top composites engineering, aerospace and motorsport manufacturers.

Used correctly, aluminium honeycomb can be used to reduce the weight and increase the stiffness of composite panels in a wide range of applications:

This very small 3.2mm / 1/8" cell size honeycomb is one of the highest specification honeycombs available. It is used in the most demanding motorsport (F1) and aerospace applications to create incredibly strong sandwich panels.

Our 3.2mm / 1/8" Aluminium Honeycomb has the smallest cell sizes of the 3 honeycombs that we offer. Smaller cell sizes means a stronger honeycomb but at the same time it is heavier and more expensive than honeycombs with a larger cell size (and therefore lower density).

How to Buy

The honeycomb listed on this page is available in 10mm, 15mm and 20mm thicknesses. Please choose the thickness you require from the options at the top of the page.

Sheets are available in blocks which will expand to a full sheet size of 2500mm x 1250mm or to a smaller sheet size of 1250mm x 652mm. Please choose the sheet size you require from the drop-down list at the top of the page.

We also stock in 1/4"e; cell size aluminium honeycomb and 3/4" cell size aluminium honeycomb.

Expanded Sheet Sizes

We stock and ship all our aluminium honeycomb in unexpanded (block) form. This makes them much smaller and more cost effective to ship but also, importantly, ensures that they are delivered undamaged, ready to be easily expanded into a faultless sheet of honeycomb.

Expanding the Aluminium Honeycomb

IMPORTANT - wear gloves before handling the block.

To Expand the block, start by using your fingers to tease some of the cells open at the edges of the block. Once you've done this we use a simply 'puller' fashioned from a strip of wood with a series of nails in. We hook the nails through the open cells and then just pull the whole assembly to open the cells. As you expand it you can unhook the cells from over the nails and move them across so they are slightly closer together (the width of the honeycomb reduces as it becomes properly expanded). It might not sound too sophisticated but it works well and the commercial expanders aren't much different.

We sell a product called ET538 Honeycomb Bonding Adhesive. Although this adhesive is primarily aimed at bonding aluminium honeycomb to composite or aluminium skins it would also be ideal for bonding the honeycomb to wood. Epoxies are well known for their excellent bond to wood and the bond to the honeycomb would also be excellent.

Start by using your fingers to tease some of the cells open at the edges of the block. Once you've done this we use a simply 'puller' fashioned from a strip of wood with a series of nails in. We hook the nails through the open cells and then just pull the whole assembly to open the cells. As you expand it you can unhook the cells from over the nails and move them across so they are slightly closer together (the width of the honeycomb reduces as it becomes properly expanded). It might not sound too sophisticated but it works well and the commercial expanders aren't much different.

This can be done by hand using a cutting template on top of the expanded honeycomb and a sharp knife to cut through the foils, or alternatively laser cutting can be used with a CAD drawn template to cut the discs more precisely and neatly.

Yes absolutely, our aluminium honeycomb is often used on laser cutting beds. We have many regular customers who use it for that exact purpose. To ensure the Honeycomb lays flat, customers usually put the honeycomb into the original manufacturers supplied bed frame or fabricate a frame of their own to suit.

What it means is that the cell walls/foil have got tiny regular perforations in the foil itself into adjoining cells. This helps to avoid any pressure imbalance between cells, especially when processing using positive (autoclave) or negative (vacuum bag) pressure.

The easiest way to cut aluminium honeycomb is to use a metal ruler as a guide and slice through the foils and cells using a stanley blade or similar. Each individual foil will cut easily and neatly as long as the blade is long enough to cut the foil in one step.

Yes, you can definitely use aluminium honeycomb in a wet-lay vac-bag process but it's almost always necessary to do this as a 'two shot' cure. By this, we mean that the outer skin of the sandwich panel should be laminated and vacuum bagged first (usually with a peel-ply finish on the inside). Once cured, the vacuum bag is removed and then you proceed with positioning the core and the inside skin which are then vacuum bagged again.

If you don't do this then you're likely to get a pretty pour finish on the outside (visible side) of the part because the pressure of the vacuum bag would only be pressing down on the laminate where the honeycomb is in contact with it, causing a sort of hexagon print pattern on the laminate.
