“…This increase could be due to the use of more flexible short fibers, fostering fewer defects during processing, 86 and consequently better fiber‐matrix interaction under compressive stresses during flexural, allowing for greater load transfer to the fibers. Mazur et al 50 in their studies associated these high results with the transfer of partial load from the matrix to the fibers and load distribution (confirmed by SEM images, Figure 4). Similar results were observed by Zhang et al 21 The results also showed that the flexural modulus varied between 195% and 190% according to P and E fibers, respectively.…”

“…Salleh et al 81 in his studies he attributes the increase in the TS and EM values as a result of the good interfacial interaction, as verified in the SEM images (Figure 4), avoiding the separation of the fiber matrix during the traction deformation. In addition, the increase in EM is a typical reaction of polymer composites to the introduction of fibers which, is caused by the reduced mobility of the polymer chain 50,82 . Furthermore, Pothan et al, 82 in his studies, claim that the mechanical properties of composites reinforced with wood flour are strongly influenced by their chemical composition, more precisely, in relation to the content of cellulose, hemicellulose and lignin.…”

“…Crystallization and melting parameters as: crystallization temperature ( T c ), melting temperature ( T m ), melting enthalpy (Δ H m ), and degree of crystallinity ( X c ) were determined. The HDPE matrix and composites crystallinity ( X c ) could be evaluated from Equation ):

X normalc (() %) = \frac{∆ H_{m}}{∆ H} \times \frac{1}{(1 - Wf)} \times 100 .

where Δ H m is melting enthalpy, Δ H is the mean melting enthalpy of fully crystalline HDPE, assumed to be 293 J g −1 , 50,51 and W f is a fraction of fibers in weight.…”

This work aimed to investigate the effect of adding short fibers of Pinus and Eucalyptus, in different granulometry (24 and 200 mesh) and concentration (0–20 m/m), combined with processing aid Struktol TPW104 (S) in obtaining of high‐density polyethylene (HDPE) composites. Overall, obtaining composites from short fibers caused relevant changes in the HDPE matrix, such as thermal stability, moisture barrier. In comparison to pure HDPE, the composites incorporated with 20% m/m of fibers, regardless of the type, decreased the melting temperature to 128°C and a wider crystallization temperature range. Another significant observation was the improvement of composites mechanical profile after adding the additive, the highest values were obtained for composites HDPEL20PS (35%—TS e 651%—EM) and HDPEL20ES (42%—TS e 681%—EM), showing good interaction and compatibility, according to scanning electron microscopy (SEM) images. The same was verified with the mechanical results of flexion and impact. Therefore, the use of short fibers and processing aid was successful providing augmented mechanical properties and thermal stability, without negatively affecting their essential properties for industrial applications.

“…By adding hydroxy valerate to a PHA network, the resulting bio-based resin demonstrates a melting temperature and mechanical properties equivalent to PE [104]. It has been demonstrated that a more sustainable and competitive BC is achievable by using bio-based high density PE (HDPE) resin with natural fibres or components, such as wood flour, flax fibres and walnut shell flour [106]. Thermoplastic starch (TPS) is another biodegradable, renewable and low-cost bio-based resin, but has unsatisfactory mechanical properties and is subject to retrogradation [107].…”

A Life Cycle Engineering Perspective on Biocomposites as a Solution for a Sustainable Recovery

et al. 2021

Composite materials, such as carbon fibre reinforced epoxies, provide more efficient structures than conventional materials through light-weighting, but the associated high energy demand during production can be extremely detrimental to the environment. Biocomposites are an emerging material class with the potential to reduce a product’s through-life environmental impact relative to wholly synthetic composites. As with most materials, there are challenges and opportunities with the adoption of biocomposites at the each stage of the life cycle. Life Cycle Engineering is a readily available tool enabling the qualification of a product’s performance, and environmental and financial impact, which can be incorporated in the conceptual development phase. Designers and engineers are beginning to actively include the environment in their workflow, allowing them to play a significant role in future sustainability strategies. This review will introduce Life Cycle Engineering and outline how the concept can offer support in the Design for the Environment, followed by a discussion of the advantages and disadvantages of biocomposites throughout their life cycle.

“…Although the main academic focus of biodegradable polymer reinforcement in recent years has been on the use of organic natural fillers [18][19][20], the use of inorganic mineral fillers such as talc [21,22], calcium carbonate [23,24], kaolin [25,26], and mica [27,28] and their impact on the biodegradability of these polymers [29][30][31] has been investigated as well. As the properties of particulate polymer composites can highly fluctuate strongly, due to variations in additional polymer additives, processing techniques, and the applied test methods, it is generally complex to compare individually reported results [32][33][34]. Therefore, this work is a comparative study on the effect of various particulate fillers (talc, calcium carbonate, kaolinite, mica) on the most important mechanical properties of a selected number of industrially available biodegradable polymers (PBS, PBSA, PHBH, and PBAT) while keeping all other factors constant.…”

Effect of Mineral Fillers on the Mechanical Properties of Commercially Available Biodegradable Polymers

et al. 2021

In the successful transition towards a circular materials economy, the implementation of biobased and biodegradable plastics is a major prerequisite. To prevent the accumulation of plastic material in the open environment, plastic products should be both recyclable and biodegradable. Research and development actions in the past few decades have led to the commercial availability of a number of polymers that fulfil both end-of-life routes. However, these biobased and biodegradable polymers typically have mechanical properties that are not on par with the non-biodegradable plastic products they intend to replace. This can be improved using particulate mineral fillers such as talc, calcium carbonate, kaolin, and mica. This study shows that composites thereof with polybutylene succinate (PBS), polyhydroxybutyrate-hexanoate (PHBH), polybutylene succinate adipate (PBSA), and polybutylene adipate terephthalate (PBAT) as matrix polymers result in plastic materials with mechanical properties ranging from tough elastic towards strong and rigid. It is demonstrated that the balance between the Young’s modulus and the impact resistance for this set of polymer composites is subtle, but a select number of investigated compositions yield a combination of industrially relevant mechanical characteristics. Finally, it is shown that the inclusion of mineral fillers into biodegradable polymers does not negate the microbial disintegration of these polymers, although the nature of the filler does affect the biodegradation rate of the matrix polymer.
