WebSeveral combinations of fiber and resin composites are analyzed, and a second trade-off analysis is carried out to select the best combination of matrix and fiber. The results show that a composite made of a PFA (poly-furfuryl-alcohol) matrix with a 50% volume ratio of Ramie fibers is the best option. Furan resin refers to polymers produced from various furan compounds, of which the most common starting materials are furfuryl alcohol and furfural. In the resin and in the cured polyfurfurol, the furan rings are not connected by conjugation. The resins are generally used as binders for sand castings. The furan … See more The term furan resins is not used uniformly in the literature. For example, some authors refer to resins based on furfuryl alcohol and furan as furan resins, while others use the term only for resins based on furfuryl … See more Before curing, the properties of furan resins are similar to those of other curable resins. They can be used as binders, are reactive to acids, … See more Furan resins based on furfuryl alcohol are produced by polycondensation under the presence of weak acids.
