Mechanical properties of injection-molded carbon fiber/polypropylene composites hybridized with Nanofillers
Composites Part A-applied Science and Manufacturing, 2013Co-Authors: Yoshihiko Arao, S. Yumitori, Kazuto Tanaka, T. Tanaka, H. Suzuki, Tsutao KatayamaAbstract:Abstract Short-carbon-fiber/polypropylene composites (CF/PP composites) have high processability and recyclability but low strength. To improve the strength, various Nanofillers were hybridized to form fiber-reinforced composites. Adding Nanofillers improves not only the strength but also the elastic modulus, with the exception of clay Nanofillers. To understand the strengthening mechanism resulting from the addition of Nanofillers, the residual fiber length and interfacial shear strength were measured. For CF/PP composites, the addition of alumina, silica, and CNT improves the interfacial shear strength, and thereby, the mechanical properties. On the basis of this result, proper choice of nanofiller type and content for improving the mechanical properties of PP/CF composites is discussed.

Impact of coated calcium carbonate Nanofillers and annealing treatments on the microstructure and gas barrier properties of poly(lactide) based nanocomposite films
Journal of Polymer Science Part B: Polymer Physics, 2016Co-Authors: Floriane Morel, Eliane Espuche, Véronique Bounor-legaré, Olivia Persynn, Marc LacroixAbstract:Amorphous poly(lactide) (PLA) and nanocomposite films were prepared from melt-blending with precipitated calcium carbonate Nanofillers (PCC). Nanocomposites based on uncoated PCC (PCC-UT), stearic acid coated PCC (PCC-S), and poly(epsilon-caprolactone) coated PCC (PCC-P) were investigated for an inorganic content fixed to 8 wt %. Using coated Nanofillers allowed preserving both PLA average molar mass and thermal stability while enhancing the nanofiller dispersion state. Poly(epsilon-caprolactone) was identified as the best coating for optimized morphology and thermal properties. Maxwell law accurately described the increase in oxygen barrier properties observed for the nanocomposites based on PCC-S. A modified Maxwell law was proposed to take account of the additional increase in barrier properties evidenced for the PLA/PCC-P nanocomposites and assigned to the particularly strong compatibility between PCL and PLA. Different annealing conditions were investigated to respectively study the impact of physical ageing and PLA crystallization on gas permeability. Different extents of physical ageing did not significantly modify the oxygen transport properties. However, a high permeability decrease was observed for the semicrystalline nanocomposites with respect to the amorphous reference PLA film. Finally, the gain in barrier properties was shown to result from both contribution of the Nanofillers and the crystalline phase.

Microstructure and properties of styrene-butadiene rubber based nanocomposites prepared from an aminosilane modified synthetic lamellar nanofiller
Journal of Polymer Science Part B: Polymer Physics, 2013Co-Authors: Kévin Dal Pont, Jean-françois Gérard, Eliane EspucheAbstract:In this work, a novel nanocomposite series based on styrene-butadiene rubber (SBR latex) and alpha-zirconium phosphate(-ZrP) lamellar Nanofillers is successfully prepared. The -ZrP lamellar filler is modified at the cation exchange capacity by -aminopropyltrimethoxysilane and the filler surface modification is first discussed. A significant improvement of the mechanical properties is obtained by using the surface modified Nanofillers. However, no modification of the gas barrier properties is observed. The impact of addition of bis(triethoxysilylpropyl)tetrasulfide (TESPT) as coupling agent in the system is discussed on the nanofiller dispersion state and on the fillermatrix interfacial bonding. Simultaneous use of modified Nanofillers and TESPT coupling agent is found out with extraordinary reinforcing effects on both mechanical and gas barrier properties and the key factors at the origin of the improvement of these properties are identified.

Modification of alpha-ZrP Nanofillers by amines of different chain length: Consequences on the morphology and mechanical properties of styrene butadiene rubber based nanocomposites
European Polymer Journal, 2012Co-Authors: Kévin Dal Pont, Jean-françois Gérard, Eliane EspucheAbstract:An aqueous slurry of alpha-ZrP lamellar Nanofillers has been modified by amine type surfactants. The influence of the alkylamine chain length and of the cationic exchange rate on the nanofiller d-spacing has been analyzed. The strength of the interactions formed between the intercalating agent and the filler has been studied by Infra Red Spectroscopy (FUR), Solid-state Nuclear Magnetic Resonance (P-31 MAS NMR) and Thermogravimetric Analysis (TGA). Different routes allowing to obtain optimized filler properties while minimizing the surfactant weight amount have been proposed from the detailed analysis of the intercalation mechanism. Styrene Butadiene Rubber nanocomposites have been prepared directly from the different slurries of modified alpha-ZrP. The dispersion of the organophilic alpha-ZrP in the SBR matrix has been characterized and the mechanical properties of the corresponding nanocomposites have been determined and discussed as a function of the filler modification, of the nanocomposite morphology and of the filler/matrix interfacial properties.
