Relationship between different mechanical properties of phenol formaldehyde SLG-reinforced composites

Abstract

Phenol formaldehyde was filled with Envirospheres, ceramic hollow spheres (SLG) to increase the tensile strength, fracture toughness and flexural strength. This paper varies the percentages by weight of the SLG in the composites which are then subjected to the relevant mechanical tests. The results show that composite with 7.5 % by weight of the SLG produces the optimum combinations of tensile properties, flexural properties, fracture toughness and cost with a reasonable fluidity for casting. It is hoped that the discussion and results in this work would not only contribute towards the development of SLG reinforced phenolic composites with better material properties, but also useful for the investigations of fracture toughness, tensile properties and flexural properties in other composites.
