| Abstract [eng] |
This study investigates the effect of the addition of star-like poly(butyl methacrylate)-poly(glycidyl methacrylate) (PBMA-PGMA) block copolymer to biobased epoxy resin on basalt fibre wettability and adhesion. Analysis of contact angle measurements of the modified epoxy resin on a surface of basalt fibre reveals improved wetting properties. Improvement in wettability is achieved despite an increase in resin viscosity, which is essential for enhancing composite quality. This finding is further confirmed by atomic force microscope analysis of the film morphology of the cured PBMA-PGMA-modified epoxy resin. The addition of 0.5 wt. % star-like copolymer remarkably increased the values of the epoxy film surface adhesion forces by 74.6%. The work of adhesion between the PBMA-PGMA-modified epoxy and basalt fibre was calculated to be 66.8 mJ/m2, slightly lower than that of the unmodified epoxy. The change in adhesion at such low levels of the star-like copolymer can be attributed to the intermolecular interactions between PBMA-PGMA and epoxy. |
