The Analysis of physical and mechanical behaviour of PP matrix reinforced with filler material and Flame Retardant as an additive

Darshan Kumar.C.D, Asha Rani.N

Present work deals with the study of physico-mechanical behaviour of Polypropylene matrix reinforced with a wood flour as a filler material and decabromodiphenyl oxide as a flame retardant. The PP has excellent mechanical properties, WF has high elastic modulus but less fire resistance so in order to improve the fire resistance the decabromodiphenyl oxide is used as a flame retardant .The PP/WF/FR fabricated composites have been evaluated for the physicalmechanical properties such as specific gravity, surface hardness, water absorption, tensile behaviour, flexural behaviour and impact strength. It was found that the tensile strength of virgin PP was 36.4MPa and that of composites lies in the range 31.4- 35.1MPa. The FR additive incorporated composites helps to enhance the flammability property but shows a slight reduction in tensile strength, however the tensile modulus increased.
