There is a monotonic decrease in strength at a similar rate for both glass/polyester and glass/phenolic composites. This implies that the fatigue strength is being governed by the reinforcement rather than the matrix. [Pg.248]

In most GRPs debonding can occur after even a small number of cycles, even at modest levels. If the material is translucent, the buildup of fatigue damage can be observed. The first signs (for example, with glass-fiber TS polyester) are that the material becomes opaque each time the load is applied. Subsequently, the opacity becomes permanent and more pronounced, as can occur in... [Pg.86]
