Effect of Impact Modifiers on Strength and Fracture Toughness of CFRPs

The aim of this work is to study the effect of core-shell rubbers on the mechanical properties of CFRPs.For the preparation of composites, two types of resins were used, a three-component Araldite resin (resin-hardener-accelerator system in proportions of 100-90-0,5 by weight respectively), and MX 1...
