Abstract
It is well known that p-aramid fiber is difficult to reinforce the polypropylene (PP) matrix with high adhesion. In addition, the conventional adhesion measurements were always extremely inconvenient. Therefore, it is necessary to simplify the adhesion measurement and also produce a p-aramid/PP composite with high adhesion. In this work, “Bundled filaments pull out (BFPO)” method as a simplified measurement was applied to measure the adhesion properties of p-aramid fiber/PP composite. The suitable processing parameters of the p-aramid fiber/PP composite preparation were also discussed from BFPO test results. Feasibility of this BFPO method was examined through comparing the tendency of adhesion between p-aramid fiber and PP by BFPO method and micro-droplet method. The resultant p-aramid fiber/PP composite prepared at 180°C with a 3 mm embedded length showed a high degree of PP impregnation. The adhesion tendency of p-aramid fiber/PP composites was mainly the same when comparing the results using BFPO method and micro-droplet method.
