EFFECT OF RUBBER PARTICLE CLUSTERING IN COMPOSITE TOUGHENING - MODEL SYSTEMS STUDY Academic Article

abstract

• Proteus particle-modified epoxy and hybrid Proteus particle/core-shell rubber (CSR) modified epoxy are used as model systems to study the effect of rubber particle clustering around the fibre/matrix interface in composite toughening. The Proteus particle is treated as a fibre phase due to its rigidity at room temperature. It is found that agglomeration of the CSR particles around Proteus particles causes premature interfacial failure of the system. Agglomeration of the rubber particles at the interface causes the main crack to propagate along the fibre/matrix interface. The designed role of rubber particles for toughening therefore diminishes. The fracture phenomena observed in the above model systems are found to be in good agreement with those of commercially available rubber-toughened polycyanate composite systems. 1993.
