The present research aimed to develop natural rubber (NR) hybrid composites reinforced with calcium carbonate/carbon black (CC/CB) and calcium carbonate/silica (CC/SC). The influence of CC/CB and CC/SC with various filler ratios (120/0, 90/5, 60/10, 30/15 and 0/20) on cure characteristics and mechanical properties of the vulcanizates was investigated and their reinforcing efficiency was compared. It has been found that incorporation of CB in the hybrid filler decreases the scorch time and cure time but increases crosslink density, whereas the incorporation of silica showed cure retardation. As CB or SC content increases, stiffness, tensile strength and tear strength increase, while elongation at break and compression set decrease. Scanning electron microscopy studies also reveal poor filler dispersion and poor adhesion between filler particles and matrix in the vulcanizates with increasing in CC content in a weight filler ratio which causes inferior mechanical properties. Incorporation of CB or SC content enhanced the mechanical properties of the vulcanizates, where CC/CB hybrid system exhibited higher reinforcing efficiency compared with CC/SC hybrid system.

Abstract The present research aimed to develop natural rubber (NR) hybrid composites reinforced with treated ultrafine calcium carbonate/carbon black (CC/CB). The influence of CC/CB with various filler ratios (50/0, 40/10, 30/20, 20/30, 10/40 and 0/50) on mechanical properties and cure characteristics of the vulcanizates was investigated and their reinforcing efficiency was compared aiming to achieve the best ratio for CB partial substitution as compared to composites with CC and CB incorporated separately. The CC30/CB20 composites reached around to 17 MPa similar strength at break response compared to CC0/CB50 (16.83 MPa). Elongation at break increased 48% in relation to CC0/CB50. Hardness maintain similar values compare to high concentration of CB composites. Crosslink density results revealed similar chain number in rubber matrix representing better interaction between CC/CB. Scanning electron microscopy studies also reveal a good filler dispersion between filler particles and matrix. The results shown that the new material can be an alternative filler for partial substitution of CB conserving mechanical properties.

Pineapple leaf fiber (PALF) having an average diameter and length of about 4 μm and 6 mm, respectively, was used as reinforcing element for natural rubber (NR) composites. PALF was coated with different amount of stearic acid at 10, 30 and 50 wt% of PALF. PALF-NR composites containing two levels of PALF at 5 and 10 part per hundred rubber (phr) were prepared in a two roll mill. Mastication times of 2, 4 and 8 min were used. Tensile stress-strain curves and fracture surfaces of both untreated PALF and stearic acid coated PALF (SA-PALF) reinforced NR prepared with different mastication times were compared. At low level of PALF where aggregation was not a problem, stearic coating had adverse effect on mechanical properties due to the slippery PALF-rubber interface. At high level of PALF, the coating gave composites with higher tensile strength and strain at break. Moreover, tensile strength and strain at break increased with increasing mastication time. This indicates that stearic acid coating reduces the formation of PALF aggregations and allows PALF to work effectively.

Green composites, especially that are reinforced with natural fibers, have received a great deal of attention due to the problems of global warming and resources depletion. Pineapple leaf fiber (PALF) is an interesting choice because of its high mechanical properties and it is obtained from agricultural waste. In this work PALF is combined with natural rubber (NR) to produce green rubber composite with enhanced mechanical properties. Since the two materials are so different in their stiffness and polarity, poor interfacial adhesion and thus low stress transfer, between NR and PALF may be expected. Attempts were made to use urea formaldehyde (UF) resin to improve the adhesion between PALF and NR. PALF was coated with different amounts of UF resin in solution. The fiber was characterized with FTIR, XPS and SEM. Uniaxially aligned PALF reinforced rubber composites with a fixed amount of 10 parts per hundred of rubber (phr) PALF were prepared. The adhesion between PALF and NR was evaluated from the tensile stress-strain curve and fracture surface of the composite. It was found that UF resin had negligible effect in improving the stress transfer but rather reduced it as shown in the stress-strain curve. Thicker coating of UF resin led to lower reinforcement effect and, hence, lower modulus. Stress at break, on the other hand, increased with increasing the coating thickness.

Manganese Zinc Ferrite

In the present work, composite materials were prepared by incorporation of manganese-zinc ferrite, carbon black and combination of ferrite and carbon black into acrylonitrile-butadiene rubber (NBR). For cross-linking of composites, standard sulfur-based curing system was applied. The main goal was to investigate the influence of the fillers on the physical-mechanical properties of composites. Then, the electromagnetic absorption shielding ability was investigated in the frequency range 1 MHz–3 GHz. The results revealed that composites filled with ferrite provide sufficient absorption shielding performance in the tested frequency range. On the other hand, ferrite behaves as an inactive filler and deteriorates the physical-mechanical characteristics of composites. Carbon black reinforces the rubber matrix and contributes to the improvement of physical-mechanical properties. However, composites filled with carbon black are not able to absorb electromagnetic radiation in the given frequency range. Finally, the combination of carbon black and ferrite resulted in the modification of both physical-mechanical characteristics and absorption shielding ability of hybrid composites.
