Hello

I am a 4th year mechanical engineering student at the University of Liverpool, and I am involved in the Human Powered Helicopter Project. For this, we are designing, building and testing a few different control methods at 1/3 scale - one of these uses a conical clutch to engage/disengage the rotor in order to distribute power across the helicopter.

After doing some research I found that common frictional materials used as clutch material include aramid cloth - I just wondered if anyone had any information regarding the frictional properties of the following product, and whether it may be suitable to be used on the face of a clutch.

Thank you in advance

You are right that aramid materials are sometimes used in high performance friction compounds such as clutch plates etc.  However from what i have seen it is a fairly specialist material and is certainly not the same as the aramid fabrics we sell which are primarily aimed for use in composite laminating.

Human powered helicopter!!!  That sounds awesome.

Following on from what Warren said, have you tried places like Ferodo?  They are over on Chapel en le frith so not a million miles from you. They should be able to help with friction materials and I'd have thought they'd help with technical help too.
