Fiberglass

[Pin Head]

I was not going to use the carbon fiber just wonder if any body has been playing with it as a shield it seams like carbon would work like graphite. Seams strange that carbon can be detected with a VLF. Will a VLF pick up heavy amounts of graphite? But I guess they are both minerals not unlike a high mineral content soil.

be carefull with polyester resin as if mixed correctly gets quite hot.

I don't have much luck with polyester resin and vlf coils but no problems with epoxy resin and fiberglass.



You could seal the spiral wrap a protected layer over top before applying the resin and fiberglass. I have not tried on a PI detector.

Hi all, Will fiberglass cloth and resin hinder the performance of a spiral wound coil? And has any body tried using carbon fiber cloth instead of glass cloth and will it act like a shield?

I have made a quick test:
A carbon fibre sheet (approximately 11"x7", from a Caterham car) is easily detected by a VLF, but you might get away with it for a PI, as long as the sample delay is not too short.

If it is based on polyester resin, it not hinder the performance.
With carbon fiber cloth I think so, but have not tried it myself.
