“…the other hand, for low concentrations of filler, good embedding may be obtained and an increase in stress occurs. 19 As the filler loading increases, it can be anticipated that filler particles will not be dispersed and wetted efficiently by the matrix. 20 These inherent defects can act as concentration points and, consequently, decreases the stress at yield and rupture of the composites.…”

ABSTRACT:Composites from SBR/PS blend and the chemically treated wood flour have been prepared. The materials used for such treatment are NaOH, MAN, MANglycidyl methacrylate, and silane coupling agent, used to improve the dispersion of wood flour in the SBR/PS blend. The effects of chemical treatment on curing characteristics, and physicomechanical and electrical properties of SBR/PS composites were studied. The rheological as well as the mechanical parameters were improved by using the modified wood flour with MAN-glycidyl methacrylate (SMG), followed by SM obtained at 15 phr, while the other treatments slightly affect these parameters. The permittivity e 0 and dielectric loss e 00 were measured in the frequency range from 100 Hz up to 100 kHz and at temperatures ranging from 30 up to 908C. The dielectric investigations indicate that the samples containing wood flour treated with both SMG and SM increase the values of e 0 and decrease those of e 00 , which allow such samples to be used in insulation purposes. The increase in the relaxation time and the crosslinking density n for such composites indicate the increase in filler-polymer interaction rather than filler-filler interaction.

“…10 On the other hand, for small amounts of filler, good embedding may be obtained and an increase in tensile strength occurs. 11 Also, the interaction between the filler and rubber matrix plays a very important role in increasing tensile strength. 12 Above 5 phr ␣-cellulose content, agglomeration and thus particle-particle interaction of the ␣-cellulose account for the observed decrease in tensile strength.…”

“…If a large amount of filler is used, the hardness achieved is high, but resilience decreases 18 because there are more points of slippage between the filler and the matrix, and also because the filler tends to clump together so that particles touch one another instead of being totally embedded in the matrix. 11 The mobility of ␣-cellulose particles and slippage of chains attributed to applied stresses on vulcanizate increase the hysteretic behavior of the vulcanizate. 16 Therefore, the resilience decreases with increasing ␣-cellulose loading.…”

ABSTRACT:In this research, the influence of adding ␣-cellulose powder to styrene-butadiene rubber (SBR) compounds was investigated. Physicomechanical properties of SBR-␣-cellulose composites, including tensile strength, elongation, Young's modulus, tear strength, hardness, abrasion, resilience, and compression set, before and after ageing, were determined and analyzed. Young's modulus, hardness, and compression set increased and elongation and resilience decreased with increasing ␣-cellulose loading in the composites, whereas tensile strength, tear strength, and abrasion resistance initially increased at low ␣-cellulose concentration (5 phr), after which these properties decreased with increasing ␣-cellulose content. Lower loadings of ␣-cellulose (5 phr) showed better results than higher loadings, given that tensile strength, tear strength, and abrasion resistance increased at low ␣-cellulose concentration. Theoretical prediction of elastic modulus was carried out using rule of mixtures, Hashin, Kerner, and Halpin-Tsai equations. Calculated results show that these equations are not suitable for accurate prediction for the work carried out. However, these models can be used with confidence for the prediction of elastic modulus because experimental results are higher than the calculated values.

“…Experimental evidence has shown that debonding is delayed to higher and higher elongations when hardness increase ( Ref 22,23). Subsequently, the obtained stress-strain results together with hardness values and SEM images suggest that there is better bonding between nanometric particles and rubber …”

We present preliminary results concerning natural rubber reinforced with nanometric ZnFe 2 O 4 obtained from an industrial solid waste. The study investigate the influence of these nanometric ceramic particles on the processing as well as the mechanical properties of the obtained rubber composite, opening the possibility of partial replacement of carbon black and exposing a new potential composite material. The hardness of unfilled and reinforced rubber increased as nanometric ZnFe 2 O 4 was increased. Besides, tensile properties of the reinforced rubber were measured, observing once again that as the amount of nanometric ZnFe 2 O 4 particles was increased, ultimate strength improved from 2.5 MPa to almost 20 MPa.
