Website offering a towelled 375g/sqm aramid fabric wanted £25/sqm plus vat, sod that for messing about with.
Took a slightly expensive punt on a roll of ex-MOD contract para-aramid from ebay. From the photos looked very thin. Seems to be around 115g/sqm, which is around 1/3 to 1/4 the weight of the aramid/kevlar I saw elsewhere. It also works out at something super low per meter too, so well worth testing and potentially making some layers to wear inside the textile kit if I was so inclined.
Testing was very unscientific.
Fire on the hob after one minute it turned to tissue but never actually burst into flames. So, fire retardancy good.
My sharp scissors cut through it with a bit of concentration. So not great as a single layer for anti-stabby but great considering I’ll have to make a pattern to sew. Multiple layers would be a nightmare to slash.
On the dremel at full speed it lasted an instant, multiple layers faired slightly better. Tested stupidly thick leather from a scrap moto jacket and I appreciate why leather is still king. Tried a piece of cordura, lasted even less time than aramid.
Pressed on the whetstone wheel spun fast, multiple layers faired very well, into the seconds at various speeds and pressures.
A silly-buggers test with two layers and my finger on the other side, after a second or two I had to lift my hand away because it was too hot, but only one layer had gone through and the other had begun to glaze.
Testing continues...
