| Abstract Scope |
The polyester resin is a different system from the epoxy resin, the ad-vantage of the polyester resin is that its cost is lower than the epoxy. The disadvantage is its permeability, because in the drying of the solvents it makes the resin porous, destroying the mechanical characteristics. Epoxy resin has no solvents and its polymerization occurs only when the two components in their proportion are mixed, the disadvantage is the need to control the temperature and humidity in the production process. In the case of polyester resin it continues to cure over time, having a better chance of cracking and breaking, while epoxy resin once cured retains its full characteristics. In the present work, pullout tests were performed to compare the interfacial adhesion with epoxy and polyester resin of the fique fibers. The results indicated a critical length ~65% higher for the fique fiber/polyester in comparison to fique fiber/epoxy and a interfacial strength 4.9 times upper, which indicates stronger adhesion of fique fiber with epoxy resin. |
