Hello
Does anyone know the kind of forces needed to shear a 2mm thick sheet of aluminium ?
Also any ideas on the same - for sandwiches of aluminium alloy layers with fibre reinforced composite in the middle ?
Thanks
Anjali
Depends on the alloy, temper, and the width of the sheet. Ultimate shear strength for aluminum alloys (and most other common metals) is in MMPDS1
Multiple ultimate shear strength of your material by the area of the sheet your cutting (2mm x width) should give you a rough approximation of the force necessary.
It would depend very strongly on the type of composite (type of fibers, type of resin, and layup). You could start poking around the web for any work on GLARE, which is the material you're describing. Airbus should know a bunch, since they use it for the skins on their A380 airplane, but I suspect anything they have is proprietary.

fibre reinforced composite in the middle ?
It depends on the angle of your shear, if you are going to use a scissor action when cutting. If you are simply chopping it off with a straight blade, then the force is simply the cross sectional area being cut multiplied by the shear strength of the material.

Contact Aviation Equipment Inc. in North Hollywood, CA (near Burbank airport) They are using GLARE to fabricate noise compliant engine cowlings. I've got a sample of their material in my lab.
Hi Harry,
I have been trying to get some Glare samples for a while now to do some basic characterisation and compare with some similar materials we are making in our university lab. It seems to be cheaper to buy diamonds than to get some Glare.
Do you have a contact email/number for Aviations Equipment Inc ?
Are you doing any research on these materials ?
Cheers
Anjali

Anjali The guy I know is named Kit Benson. He actually lives a couple of block from me, although I don't see him much amymore. Best to just call the company at 818-982-6700 and ask for the sales rep, or email them at snipped-for-privacy@avequip.com They sent me a 4 foot x 4 foot piece of 3/2 GLARE 5, which is 0.100 inch thick. We worked with it on a specific defense project that was reduced in scope after start. The material performed as advertised.
