Im tryng to boost up a level of biocomposite panel for high impact velocity resistant, any suggestion?

i am available to discuss syntactic foams(particulate composites)

i am working on self healing system

I have worked with fiber-placed, thick walled, carbon-fiber / epoxy composites at Lockheed Aeronautics. When the diameter / thickness ratio of the structure gets small, the resin cure shrinkage can cause problems with delaminations. You'd have to experiment a bit with your own materials, but we resolved our issues with multiple intermediate cures. Our diameter / thickness ratio was 4, with a 2" thickness.

if u ppl are talking about composites..please make sure to narrow them down to the following
metal composites
fiber composites
particulate composites

I'm looking for a non-conductive material that will handle 9,000 degrees F on a continuous basis. Will be used for active high tempature electrical arc shielding. Have looked at HfB2 as a possible, but due to restrictions having trouble obtaining it. Any help would be greatly appreciated.

I have designed and molded many thick parts (up to 2" wall) for oil & gas as well as medical/surgical. I specialize in contionous fiber thermoplastic compisites. Using these you do not need to worry about the temperture profile of thick laminates. We also do very thin parts, .025 - .060 for enclosures ETC.

In the past, I have worked in developing CNC machinery for the contouring, gluing, and assembly of thick composites for military aircraft.

My current interests are in thinner composites for personal watercraft and light aircraft, as well as composites which include metal and ceramics along with the usual fibers and resins.

Anyone worked with thick walled composites? not so much interested in weight but more structural strength and thermal resistance for oil feild applications. It seems that as the parts are made thicker the laminate layers become a bit tricky in holding together, requiring staged curing. Anyone?

Is anyone interested in MMC material. In particular Aluminium / ceramic MMC's?

I'm available to discuss thermoplastic composite application and design.
