Effect of Water Immersion on Fiber/Matrix Adhesion in Thermoplastic Composites.
Abstract
Continuous fiber reinforced thermoplastics were tested for the effect of water immersion on fiber/matrix adhesion. The materials evaluated were E/PPS, AS4/PPS, E/J2, AS4/J2, S2/PEEK, AS4/PEEK, S2/PEKK, AS4/PEKK, and S2/VECTRA. These materials were tested in uniaxial compression, transverse flexure, and short beam shear, both dry and water-conditioned. Scanning electron microscopy was used to assess the quality of the fiber/matrix bond. The carbon reinforced materials retained adhesion after water immersion. However, the glass reinforced thermoplastics were in general degraded by water, which hydrolyzed the fiber/matrix bond and significantly reduced mechanical properties....
