Harper pioneered the Microline® concept based on flexibility and versatility to change and modify equipment parameters for the needs of customers in Carbon Fiber research for experimentation with traditional or emerging precursors, process tweaking and development of samples for up to 1.5 tons per year. Our system accommodates line speeds ranging from 0.1 m/min to over 1 m/min and tows from 10 filaments to 48000 filaments, enabling the study of effects of various process parameters using a small amount of precursor.
