Quasi-Static Shear Test of Hybrid Adhesive Bonds Based on Treated Cotton-Epoxy Resin Layer

Popis výsledku v původním jazyce

This research evaluates mechanical properties of hybrid adhesive bonds with various 100% cotton fabrics in static and quasi-static conditions and influence of alkali surface treatment (NaOH) of the cotton fabrics on mechanical properties. Biological fibers in polymer are characterised by low wettability with matrix, which decrease mechanical properties. Adhesive bonds usually operate in cyclic stress, which causes irreversible failure before maximal strength. The quasi-static test loaded the adhesive bonds in interval 5-50% (192-1951 N) and 5-70% (192-2732 N) with 1000 cycles. The results of SEM analysis proved good wettability of alkali treated cotton fabric with NaOH solution in hybrid adhesive bonds. Static test proved influence of reinforcing cotton fabrics on shear tensile strength against pure resin, i.e. Erik up to 19% on 14,90+/-1,15 MPa and Tera up to 21% on 15,28+/-1,05 MPa. The adhesive bonds with simple resin did not resist neither quasi-static tests. Reinforcing cotton fabrics resisted b
