Flexural and inflammability properties of FA/CF/Phenolic hybrid composite

The application of polymer composite in industry should meet good mechanical and inflammability properties due to its risk on failure under loading and its flammable property of polymer. The use of Fly ash (FA) waste whose high in flammability and carbon fiber (CF) whose high thermal conductivity and self-extenguish characteristic is expected can give solution to accelerate its application and to reduce its cost. The composite was produced by using a simple molding which was varied in FA and CF contents. The testing of the samples were conducted with universal testing machine for flexural test and horizontal burning apparatus for flammability test. The result shows that the use of FA on FA/Phenolic composite has good performance on increasing in flexural strength and inflammability. The FA is also give contribution on cost reduction of the composite. The CF addition in FA/CF/Phenolic composite give on enhancing of flexural and inflammability properties. The FA/CF/Phenolic hybrid composite has best performance on flexural and inflammability properties for 30% of FA content (w/w) and 4 laminates of CF. The addition of FA should be proportional so that the particles can be fully bounded by the matrix.
