|Title:||Unsaturated polyester resin modified with poly(organosiloxanes). II. Acoustic emission study on glass-fiber-reinforced resin|
|Abstract:||This work aims to study the adhesion of an isophthalic acid based unsaturated polyester resin chemically modified by grafting copolymerization of a poly(organosiloxane) to the glass fiber. The failure mode of the single-edge notched tensile specimen, cut from pressed plates containing 50 wt % of nontreated and silane-treated milled glass fiber, was studied by acoustic emission (AE) technique. It was found that the aforementioned resin modification enhanced the adhesion between the fiber and the resin. This was suggested by a shift in the AE amplitude and energy toward higher values. On the other hand, the matrix modification had no significant effect if glass fiber with suitable unsaturated polyester resin (UP) sizing was incorporated. (C) 2001 John Wiley & Sons, Inc.|
