MARIANA, Etcheverry; FERREIRA, María L; CAPIATI, Numa J  y  BARBOSA, Silvia E. Glass-fiber Coating Influence on the Effectiveness of Propylene-Glass Copolymerization Reaction. Inf. tecnol. [online]. 2011, vol.22, n.5, pp. 77-82. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642011000500010.

The influence of fiber coatings on the effectiveness of the propylene-glass copolymerization reaction has been analyzed. The mechanical properties of fiber reinforced composites depend on the effective stress transfer fiber-matrix, which is possible if the adhesion between them is strong. An alternative method to improve the adhesion is the establishment of chemical links between matrix-fiber such as in situ polymerization. The study was carried out on sandwich composite of polypropylene and fiber glass, with and without acrylic coating. Adhesion is analyzed through its influence on the mechanical properties of the composites. The copolymerization reaction acts as an effective bonding agent, when it is carried out on uncoated fibers, making this proposal technological attractive.

Palabras clave : composites; in-situ polymerization; fiber coating; adhesion.
