“…The same study demonstrates a negligible effect of nanosilica on the thermal and flammability features of PA11. The increase of the mechanical strength, stiffness and toughness was achieved for PA11 composite reinforced with 10 wt% of HNT [12]. An improvement of the shear modulus in the glassy and rubbery plateau, as well as a change from ductile to fragile behaviour has been reported for a composite with 12 vol% of BaTiO 3 nanoparticles [13].…”

“…In these cases, advanced composite properties are commonly associated with full exfoliation of clays (62 wt%) in polymer matrix [8,9]. More recently, the effects of multi-walled carbon nanotubes (MWCNT) and nanofibers (CNF), nanosilica (NS), halloysite nanotubes (HNT) and BaTiO 3 nanoparticles on the thermal and mechanical properties of PA11-based composites have also been reported and discussed [10][11][12][13]. The obtained results show that the composite's thermal stability improves by about 20°C when the concentration of MWCNT is 1 wt%, whereas the gradual increase of the storage modulus by about 54% is noticed with the rise of the MWCNT content up to 2 wt% [10].…”

“…In order to evaluate the thermal combustion properties of BMCs, a micro‐scale combustion calorimeter (MCC) (Govmark, Farmingdale, NY) was used in agreement with ASTM D7309‐07 . With MCC it is possible to measure the HRR of a small amount of material (order of milligrams).…”

In this work, the use of nano‐boron carbide as a nanomodifier of phenolic matrix was envisioned. Particularly, nano‐boron carbide/phenolic‐based nanocomposites were produced and investigated. The obtained nanostructured matrices were also used to produce carbon fiber‐based bulk molding compounds (BMC). The thermal stability of nanocomposites and BMCs was investigated by thermogravimetric analysis both in nitrogen and in air atmospheres. The good dispersion and distribution of the nanosized particles in the matrix was confirmed by transmission electron microscopy while the post‐burning appearance of the BMCs was investigated by visual inspection and scanning electron microscopy. The experimental data highlighted the remarkable effects of nano‐boron carbide on the thermal stability and oxidation resistance of the carbon fiber‐based BMCs. Moreover, the boron oxide produced by the conversion of boron carbide allowed a substantial improvement of the dimensional stability of the BMC which also exhibited considerable residual structural integrity after burning.

“…It is biocompatible and has the advantage of being less hydrophilic than the commonly used polyamide‐6 and polyamide‐6,6 . Moreover, the polymer offers excellent piezoelectric properties, a low wear and abrasion, and high chemical resistance . It is therefore widely used in a large range of fields from automotive to offshore applications , despite its low impact strength, tensile strength, and thermal properties .…”

Accelerated photooxidation under ultraviolet (UV) test of polyamide 11 (PA11) films filled with unmodified vermiculite clay at 5 wt% was investigated up to 600 h. Film samples of ~60‐μm thick were prepared by melt compounding using a cast extruder and exposed to UV light irradiation at λ > 295 nm. Fourier transform infrared (FTIR) spectra indicated similar structural changes occurring in both PA11 and PA11/unmodified vermiculite nanoclay (UVMC) nanocomposite along the photooxidation process, resulting in imides and carboxylic acids as the main carbonyl products. It was however observed that the formation rate of carbonyls in the PA11/UVMC nanocomposite was slower than neat PA11. This behavior is consistent with the yellowing index evolution determined by ultraviolet–visible (UV–vis) spectroscopy. Further, the photooxidation stability of the samples was also evaluated by the onset oxidation temperature determined by differential scanning calorimetry. The results indicated a better stability of the nanocomposite film than neat PA11, corroborating well the data obtained by FTIR and UV–vis techniques. POLYM. ENG.
