Mechanical properties of continuous bamboo fiber‐reinforced biobased polyamide 11 composites

Abstract

This study is devoted to the analysis of the properties of continuous bamboo fiber (BF)-reinforced polyamide 11 (PA 11) composites. The SEM observations highlighted continuity between BFs and the polymeric matrix showing a high density of hydrogen bonds. The comparative calorimetric study of the matrix and its composites showed that the crystallinity of PA 11 was not modified by the presence of bamboo fibers. The physical aging observed in PA 11 is no more observed in composites due to physical interactions between PA 11 and BFs. The mechanical properties were investigated by tensile strength and dynamic mechanical analysis. The introduction of BFs enhanced Young's modulus of the matrix by a factor of 10. The presence of BFs also improved the storage shear modulus G 0 over the whole temperature range.

Investigation of 3D printing strategy on the mechanical performance of coextruded continuous carbon fiber reinforced PETG

“…Various continuous fibers have been used to reinforce the mechanical properties of thermoplastic polymers including Kevlar, 22 carbon, 23 glass, 24 and bamboo, 25 but it appears that continuous carbon fibers (CCFs) give the best mechanical improvements 2 . FFF parameters influenced the mechanical properties of continuous fibers‐reinforced thermoplastic polymers 26,27 .…”

Bio-Polyamide 11 Hybrid Composites Reinforced with Basalt/Flax Interwoven Fibers: A Tough Green Composite for Semi-Structural Applications

“…Despite its relatively high costs, in the last decade, PA11 has gained a special industrial interest due to a good combination of mechanical properties and chemical resistance. In particular, PA11 exhibits good toughness compared to other bio-based thermoplastic resins, e.g., poly(lactic acid), which is often proposed as a matrix for bio-composites [11][12][13][14][15]. As far as the fibers are concerned, here we deal with a hybrid fabric made of basalt and flax interwoven fibers in 2/2 twill structure.…”

A synthesized semi‐aromatic copolyamaide through synergy of three different kinds of monomers: Toward high transparency, excellent heat resistance and melt flowing property

“…The sharp peak in the figure was resulted from the alpha relaxation, and the temperature of which is corresponding to the glass transition temperature (T g-DMA ). [30][31][32] The detailed results are shown in Table 4. With the increase of PACMI content, T g-DMA shows almost the same variation tendency and numerical value with T g measured by DSC.…”
