Effect of Impact Modifiers on Strength and Fracture Toughness of CFRPs

The aim of this work is to study the effect core-shell rubbers on mechanical properties CFRPs.For preparation composites, two types resins were used, a three-component Araldite resin (resin-hardener-accelerator system in proportions 100-90-0,5 by weight respectively), and MX 156, which contains 25 % elastomers 75 resin. Depending test, carbon fibre fabrics (UD C415, G0926) are used with corresponding number layers. composites prepared vacuum infusion cut appropriate dimensions water-cutting. They tested for performance, bending, shearing, tensile, impact fracture toughness tests, compare CSR-containing reference CFRPs. Fracture analysis specimens was performed scanning electron microscopy (SEM). results exhibited 50% increase strength while energy absorbed during test 4 times greater CSR than reference.
