Abstract

One of the main problems of composites is fire resistance properties. New fire-retardant additives are able to modestly improve this problem, although mechanical properties can be depleted.

For this reason, a large variety of phosphorus-based flame retardants have been studied for their flammability and their rheological and mechanical properties [1,2]. However, little research has been done on the mechanical and rheological properties of epoxy resins with non-halogenated flame retardants, and these must be at least mentioned in conjunction with the fire retardant characteristics, in order to acquire a global view of the compound.

In this work, the correlation between the addition of non- halogenated flame retardants and the mechanical properties of composites (tensile properties, interlaminar shear, flexure) and different types of fiber (basalt and glass) has been researched.
