Performance of Plasma Treated Polymer Macro-Fibers
Original language description
Concrix – commercial bi-components polyolefin macro-fibers (ø 0.5 mm, length 50 mm) made by BURG Group in Switzerland were plasma treated to attain the better adhesion with cement matrix. Fibers were exposed to oxygen treatment in inductively coupled plasma system by different times (from 5 to 480 seconds.). The influence of realized fiber surface treatments was observed by physical and mechanical methods: i) horizontal direct optical method enabling a measurement of fibers wettability, ii) fibers tensile strength tests, and iii) single-fiber pull-out tests from cement matrix. It turned out that fibers treated by plasma during 30 seconds reached the best ratio between their wettability and mechanical performance. While their contact angles decreased by ca. 50 %, tensile strength remained constant and cohesion with cement matrix increased by ca. 20 % in comparison with reference fibers.
