Abstract: A process of preparing carbon fiber reinforced polymer (CFRP) intermediate products is described wherein the carbon fibers are prepared from a carbon fiber precursor and then in-line impregnated with a polymeric resin as part of a continuous process. The process can provide cost savings compared to processes wherein carbon fibers are prepared and then impregnated with polymeric resins in a separate process, thereby making the use of CFRP materials more economically feasible. Also described is a system for preparing carbon fiber from a carbon fiber precursor and impregnating the carbon fiber with polymeric resin to provide CFRP intermediate products, such as continuous tapes or rods or discontinuous flakes or pellets.

Abstract: A process of preparing carbon fiber reinforced polymer (CFRP) intermediate products is described wherein carbon fiber tows, such >50 K or 100K textile grade carbon fiber tows, are spread and contacted with a sheet of molten polymer resin. Also described is a system for preparing CFRP intermediate products, such as continuous tapes, and the CFRP intermediate products themselves.

Abstract: Filter media comprising cellulose fibers and fibrillated thermoplastic fibers, such as fibrillated polyolefins are described. The filter media can be provided in the form of non-woven fiber mats (e.g., wet-laid non-woven fiber mats) that can be integrated into air filtration devices to enhance their biodegradability. The non-woven fiber mats can be prepared as electrets. Composites comprising multiple layers of the same or different filter media can be prepared. Composites having minimum efficiency reporting value (MERV) ratings of at least 12 or at least 13 are described.
