“…Similar results, such as decreasing of the impact strength of composites with increasing MCC loading, were also observed in other studies (Zaini et al 1996;Bengtsson and Oksman 2006;Kiziltas et al 2010;Zulkifli et al 2015). Such findings can be attributed to an increase in its brittleness due of addition of the high amounts of MCC into the polymer matrix (Cavdar et al 2015). Kiziltas et al (2010) reported that polymer mobility increases with increasing MCC content and leads to lower impact strength.…”

“…MCC did not seriously affect tensile strength of the composites, while nutshell resulted in a minor decrease in tensile strength. This can be related to differentiation between the size of MCC (40 µm) and nutshell fiber (0.5 mm) (Cavdar et al 2015). As also shown in Fig.1, the variance analysis indicated that MCC loading had a significant effect on tensile strength and tensile modulus.…”

Effects of nutshell fiber loadings of 30 wt.% and MCC loadings up to 15 wt.% on some properties of high-density polyethylene composites (HDPE) were investigated. The composites were manufactured by a single screw extruder and injection molding. The experimental composite samples were tested for their mechanical performance including tensile strength, tensile modulus, flexural strength, flexural modulus, and impact strength. Thermal and morphological properties of the composites were tested by differential scanning calorimetry-DSC and scanning electron microscopy (SEM), respectively. The maximum tensile strength was obtained from the MCC-filled composites, whereas the maximum flexural strength was achieved with the MCC-nutshell filled composites. The tensile and flexural moduli of the composites were significantly improved with increasing MCC content and the presence of nutshell fibers in polymer matrix. Impact strength decreased using MCC and nutshell fiber in the polymer matrix. Based on the DSC results, there was no remarkable change in the melting point for all composites. The results showed that the incorporation of nutshell fibers and MCC in the polymer matrix had brought about some positive effect on mechanical properties of HDPE composites.

“…Elongation at break was sharply decreased when cupula fiber filled in the polymer matrix. It is known that natural fibers make the composites more brittle with addition in polymer matrix because the fibers have higher brittleness and rigid than the HDPE . In the light of these results, the cupula fiber filled r‐HDPE composites produced with alkali treated fibers at 40 wt% loading have optimum mechanical properties.…”

The objective of this study is to investigate the effects of alkali treatment on the mechanical, physical properties of cupula fibers reinforced recycled high density polyethylene (r-HDPE) composites. The composites were produced with different chestnut (Castanea sativa Mill.) cupula fiber contents, up to 50%, and polyethylene-grafted maleic anhydride. The mechanical, physical, thermal, and morphological properties of the treated and untreated samples were investigated. In addition, the Fourier transform infrared spectroscopy (FTIR) was used to observe the interactions and functional groups between cupula fiber and r-HDPE in the composite samples. The alkali treatment with 5 wt% NaOH solution had an affirmative effect on the tensile and flexural properties. It was found that an increase of 20% in flexural strength values with up to 40 wt% alkali treated cupula fiber loading in polymer matrix compared to that of untreated samples. After 5 wt% NaOH treatment, the crystallinity decreased with the increase of the chestnut cupula fiber ratio. As excepted, the FTIR analysis showed that the alkali treatment resulted in removal of hemicellulose, and lignin from cupula fiber.The results revealed that the alkali treated chestnut cupula fiber can be used successfully in polymer composites as a natural fiber filler.

“…Hence, the reinforced composite becomes more rigid then neat polymer matrix. [ 6, 46, 47 ] The increase of rigidity in the composites was not observed when AKD added in the polymer matrix. FMOE of the filler reinforced composites decreased in the presence of AKD.…”

In this study, the effect of alkyl ketene dimer (AKD) on the mechanical and physical properties of natural fiber (NF) and glass fiber (GF) reinforced poly(lactic acid) (PLA) composites were investigated in detail. The hybrid PLA composites were manufactured by extrusion method followed by hot press molding. AKD was used to improve the hydrophobicity of hybrid PLA composites and compatibility of NF and PLA in the polymer matrix. The tensile and flexural tests, thickness swelling, water absorption, and contact angle measurements were accomplished for determining the performance of the hybrid PLA composites. The surface morphology of the hybrid PLA composites was also performed by scanning electron microscopy. The incorporation of AKD and NF into PLA matrix improved the mechanical strengths by 40% and above compared to those of samples without AKD. But, tensile and flexural moduli decreased as 7% and 14% of the samples with NF and AKD, respectively. Contact angle was higher for the hybrid PLA composites with AKD compared with the composites without AKD. However, the results revealed that in the presence of GF, AKD had no significant effect on overall properties of the hybrid PLA composites. In the light of the findings, AKD may have a potential usage as coupling agent in the NF filled PLA composites.
