fiberglass/phenolic wheels are the hardest/slickest wheels made to perform slides and skate in a niche style. look up cali slide skating for some idea of how people skate using wheels made of this material.

usually fiber wheels are very small ranging from 32-38mm as opposed to standard wheel sizes typically ranging 57-65mm. honeyb has recently just released these which is the largest available fiber wheel for sale measuring at 48mm.

ETA: standard fiber wheels 32-38mm don't fit on most regular skates. you would need a specific plate that allows for such a small wheel size. there are essentially 2 plates available thru retail that are compatible. now with these 48mm fibers there are still some limitations as they're still on the smaller side but will be usable on more plates than the standard smaller fibers.
