| dc.description.abstract | Among the challenges that particle-filled plastics composites (PFPCs) present is the complexity of their mechanical behavior, particularly during plastic deformation. This challenge cannot be overlooked in need by most modern designs for materials with a combination of properties such as stiffness and strength than conventional plastics cannot meet. Thus, in this paper, detailed discussions on the influence of three failure modes, namely: matrix failure, failure of the particulate fillers, and interfacial decohesion on the mechanical stability of PFPCs, were done. The relationship between the matrix crack and the particulate filler was also discussed. At the same time, the mechanical behaviour of PFPCs when subjected to tensile, compressive, and impact loading was also reviewed. It is shown that the type of failure experienced by the particulate composite is influenced significantly by the mismatch in ductility and elastic modulus between the particulate fillers and the matrix. Factors such as temperature variation, increase in strain rate, presence of a sharp notch, formation of voids in the matrix, and poor adhesion between matrix and particle fillers with increased particle size also affect the failure mode experienced by the particulate composite. | en_US |
