“…For this purpose, the Bader and Bowyer (B-B) model was considered. This model has been successfully adopted for various composite systems containing natural fibers [ 62 , 63 , 64 , 65 , 66 , 67 , 68 ].…”

Effect of a Bio-Based Dispersing Aid (Einar® 101) on PLA-Arbocel® Biocomposites: Evaluation of the Interfacial Shear Stress on the Final Mechanical Properties

In this paper, the production and the characterization of poly (lactic) acid (PLA)-based composites containing different amounts (from 10 wt.% to 25 wt.%) of ultra-short cellulose fibers (Arbocel 600 BE/PU) have been investigated. On the basis of a previous study, it was observed that the addition of the cellulose fibers led to an embrittlement of the composite. Consequently, in order to obtain a composite with enhanced impact resistance and elongation at break, the effect of the Einar 101 addition (a bio-based dispersing aid additive) was analyzed. The role of the adhesion between the fiber and the matrix, coupled with a better fiber dispersion, was thus evaluated. Also, the consequences on the final mechanical properties (tensile and impact test) caused by the Einar addition were investigated. Analytical models were also applied in order to obtain an evaluation of the variation of the interfacial shear stress (IFSS) (strictly correlated to the fiber-matrix adhesion) caused by the Einar introduction. Furthermore, due to the very low aspect ratio of the Arbocel fibers, a suitable Bader and Boyer model variation was adopted in order to have a better quantitative estimation of the IFSS value.

“…The same approach (analysis of stress-strain curves) was successfully applied to polypropylene reinforced with flax and hemp fibers. [17][18][19] The volumetric composition of composites, V f , V m , and V p , can be shown to be correlated to the fiber weight fraction, W f , in the whole range from W f ¼ 0 (only matrix) to W f ¼ 1.0 (only fibers). In the present study, a previously developed model 20 will be used for the region where W f is below a transition value given by the maximum fiber volume fraction of the composites…”

In this experimental study, the performance of injection-molded short flax and hemp fibers in plasticized starch acetate were analyzed in terms of strength. Parameters involved in the analysis are a variable fiber and plasticizer content. The measured strength of the composites varies in the range of 12–51 MPa for flax fibers and 11–42 MPa for hemp fibers, which is significantly higher than the properties of the unreinforced starch acetate matrix. The micro-structural parameters used in modeling of composite strength were obtained from optical observations and indirect measurements. Some of these parameters were qualitatively verified by X-ray microtomography.

“…In short-fiber composites, the IFSS has been found to either decrease with increasing content of inorganic [14-16, 46, 47] and natural [19][20][21]24] fibers, stay approximately constant, [48,49] and [23,27], respectively, or even increase [42,50] with it. It has been proposed in [51] that the apparent IFSS can be expressed as the sum of two…”

“…Subsequently, using the whole experimental stress-strain curve of the composite, rather than only two points, was proposed in [17,18] for estimation of its IFSS. The composite-test-based approach has also been applied to the evaluation of the IFSS of natural fibers, such as, e.g., flax [19][20][21], hemp [22][23][24], corn stalk [25], stone groundwood [26], old newspaper [27], and orange tree pruning pulp [28] fibers and polypropylene matrices, as well as hemp fibers and a Mater-Bi ® thermoplastic starch matrix [29].…”

Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. found to be greater for composites with a higher fiber loading and to decrease with increasing content of plasticizer. The IFSS is equal or greater than the yield strength of the neat polymer, suggesting good adhesion, as expected for the chemically compatible constituents.
