You now just need a flat surface to work on and an assistant to help you expand the honeycomb. Repeat for the second batten so you have two identical battens with nails sticking out. The final result should be a batten with regular nails poking through. Once marked, hammer the nails through the dots marked on the batten (taking care nothing is underneath!). Take one of the battens and mark out a series of dots on the wood along the battens length spaced at approximately 50mm intervals. They need to be long enough so that they can go through both the wooden batten and still protrude enough to go through the honeycomb.įor cutting honeycomb you need a steel ruler and a sharp Stanley type knife with a blade long enough to cut through the honeycomb to its full thickness in one go. 2” by 4” wooden battens are usually ideal and easily obtained. You will need 2 wooden battens, both as wide as the sheet you are expanding and stiff enough not to flex too much. The aim of this guide is to show you a simple method that can be used to successfully expand the sheet by hand. However, for smaller applications and one off jobs, such machinery is prohibitively expensive and large thus an alternative method is needed. In large scale manufacturing, a specialist expanding machine is used to expand the honeycomb. This is for two reasons, firstly because expanded honeycomb would be expensive to ship, and secondly because in its expanded un-stabilised form, the honeycomb is very susceptible to damage and would unlikely survive transport intact. IMPORTANT - wear gloves before handling the block.Ĭommonly Aluminium Honeycomb is supplied as an unexpanded block. 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. We stock and ship all our aluminium honeycomb in unexpanded (block) form. We also stock in 1/8"e cell size aluminium honeycomb and 3/4" cell size aluminium honeycomb. Please choose the sheet size you require from the drop-down list 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 thickness you require from the options at the top of the page. The honeycomb listed on this page is available in 10mm, 15mm and 20mm thicknesses. The 6.4mm / 1/4" cell size is a good balance between strength, weight and cost making this our most popular aluminium honeycomb. This medium 6.4mm / 1/4" cell size honeycomb is an excellent 'all rounder' honeycomb suitable for a wide range of applications including motorsport, marine, renewable energy and transport. Used correctly, aluminium honeycomb can be used to reduce the weight and increase the stiffness of composite panels in a wide range of applications: High performance aluminium honeycomb core material exactly as supplied to the world's top composites engineering, aerospace and motorsport manufacturers.
