“…In the investigation of fractured surfaces, Liang and Wu investigated the relationship between the fracture surface fractal dimension and the impact strength of polypropylene nanocomposites. A strong correlation was observed, and it indicated that the fracture surface of the composites was fractal, and the relationship between the impact strength and fractal dimension of the composites obeyed roughly exponential function [7]. Lung et al have also demonstrated that there is a relation between the roughness and the fractal dimension of the surface [45].…”

“…The phenomenon of fractal is ubiquitous in a wide array of materials, such as the fracture of nanoparticle composites [6][7][8], the growth of crystal [9][10][11][12], the quasicrystal structure [13], the fracture of martensite morphology [14,15], the porous materials [16][17][18][19], and the deposited film [20][21][22][23][24][25]. These materials are of uncommon class of disordered materials and usually show complex microstructures.…”

A fractal is an object or a structure that is self-similar in all length scales. Fractal geometry is an excellent mathematical tool used in the study of irregular geometric objects. The concept of the fractal dimension, D, as a measure of complexity is defined. The concept of fractal geometry is closely linked to scale invariance, and it provides a framework for the analysis of natural phenomena in various scientific and engineering domains. The relevance of the power law scaling relationships is discussed. Fractal characteristics of porous media and the characteristic method of the porous media are also discussed. Different methods of analysis on the permeability of porous media are discussed in this chapter.

“…Polypropylene (PP) is a general resin with good insulation properties, small dielectric constant, good stress crack resistance and chemical resistance. [7][8][9] However, PP resin has a poor flammability resistance and can continue to burn and cause flaming drips when ignited. In order to widen the applications of PP, flame retardants are usually added into this material for enhancing its flame-retarding ability.…”

The effects of the microencapsulated red phosphorus (MRP) content and specimen thickness on the mechanical properties of the filled polypropylene (PP) composites were studied at room temperature. The results showed that the influence of the MRP on the tensile and impact properties of the composites was significant, and the Young's modulus and impact strength of the composites increased nonlinearly while the tensile strength decreased slightly with increasing the MRP weight fraction; the tensile elongation at break increased outstandingly when the MRP weight fraction was less than 2% and then decreased with increasing the MRP weight fraction. Furthermore, the impact fracture surface was examined by scanning electronic microscope. The results suggested that the toughening effect was attributed to the absorption of impact fracture energy by the microencapsulated layer.

“…The reinforcement of polymers with natural cellulosic fibers combines the unique properties of the polymer with strength and stiffness of the fibers. In fact, natural fiber reinforced composite is an emerging area in polymer science 18–22. The use of natural fibers to develop composite materials for useful applications is increasing these days because it is expected to reduce the dependence on nonrenewable resources and to lessen the energy crisis on account of the consumption of nonrenewable resources 23–27.…”

Renewable cellulosic biofibers appear to be a promising substitute to synthetic fibers as reinforcement in different kinds of polymers. The prime objective of this work was to determine water absorption, chemical resistance, and mechanical properties of the green composites reinforced with ecofriendly natural cellulosic Saccharum cilliare fibers. The mechanical and physicochemical properties of the green composites have been investigated as a function of fiber loading for assessing their applicability in different potential applications in everyday life. The green composites thus prepared have been Correspondence NATURAL CELLULOSIC POLYMERS AS POTENTIAL REINFORCEMENT IN COMPOSITES found to show a universal trend of an increase in properties with fiber loading up to 30%, and beyond this the properties decrease. A fiber/matrix interaction between the polymer and reinforcement has been analyzed based on the mechanical and morphological studies. Overall results suggest that the natural cellulosic S. cilliare fibers were capable of serving as a feasible reinforcement for green polymer composites. C 2012 Wiley Periodicals, Inc.
