Among the several available techniques to produce the braided composite rods for construction industry, nidltrusion process is becoming the most widespread and cost-effective continuous processing technique. The work mentions the influence of carboxyl functionalized multiwalled carbon nanotubes (MWCNTs) on the maximum speed of manufacturing process. The epoxy polymer is diglycidyl ether of bisphenol F and the curing agent is an aromatic diamine. Appropriate temperature settings were determined using the optimization algorithm for two-dimensional heat transfer and curing model implemented to 8-mm diameter reinforcement with 0, 0.1, 0.2 and 0.3 wt% MWCNT. Final results allow concluding that only the use of 0.2 wt% MWCNT gives the highest nidltrusion speed. Other two batches (0.1 wt% and 0.3 wt% MWCNT) showed worse results compared to neat sample. The developed optimization algorithm can be further applied in the modeling of pultrusion process with using of different type of resin, curing agents and nanofillers.
