I was under the impression that class III trauma plates (for rifle fire) were made of compressed and kiln-fired boron carbide or another very hard ceramic and that soft body armor was simply many layers of kevlar sewn together with heavy nylon on the outside. I've never heard of compressing the kevlar layers beyond quilting them together.
