Abstract
Improved fiber resin matrix prepreg fabrics are disclosed which are comprised of a first layer of reinforcing fabric coated with an epoxy resin composition and a discrete second layer of an epoxy resin modified with an elastomeric polymer. The discrete second layer is provided with a support comprising a gauze-like, lightweight fibrous mat or carrier of lightweight fibers that preserves the second 'interleaf' layer during cure. Cured composites having the continuous interleaf layer intact exhibit high impact strength and resistance to impact damage. 6
