Uniaxial strain and uniaxial stress preloadings were performed on quartz phenolic in order to assess the effect of an impulsive preload on the subsequent uniaxial stress behavior of a composite material. In these tests observable damage was limited to the phenolic matrix. As a result, postpreload experiments on the specimen under uniaxial stress correlated the dependence of the fracture strength with the extent of the damage to the phenolic matrix as well as the direction of the reload relative to the fiber layup.
