“…Elastic (or storage) modulus is related to the stiffness and elastic behavior of a material. 45 It is seen in Figure 10(a) that the elastic modulus of the samples decreases with the increase in temperature, which is due to the softening of the PP matrix and increase in the mobility of the polymer chains. 46,47 The modulus of the composites also increases with the increase in the fiber concentration, which is much more evident after 60°C.…”

This study investigated the mechanical properties of polypropylene composites reinforced with short natural fibers obtained from plane tree ( Platanus orientalis L.) fruits. The fibers were harvested from the fruits that naturally fell from the tree in their standard length of about 6 mm. Composites were produced via melt blending using varied concentrations of the fibers (5–10–20–30 wt.%) and maleic anhydride grafted polypropylene (MAPP) copolymer as the coupling agent. The mechanical properties of the composites were characterized by tensile test, flexural test, dynamic mechanic analysis and ball-on-disc sliding wear test. The findings revealed that the fibers had a significant effect on the mechanical properties of the polypropylene matrix and the properties were found to improve linearly with increasing fiber concentration. At a 30 wt.% fiber concentration, the tensile and flexural strengths increased about 28% and 36% compared to pure polypropylene, respectively. At this fiber concentration, the modulus doubled compared to the pristine polymer. This increase is higher than that reported for most other natural fibers. Good miscibility between fibers and matrix, enhanced thermal stability, and about 30% reduction in friction coefficients were found. As a result, PTFs have the potential to be used in industries such as automotive, construction and sports which require mechanical strength and low weight.

“…The loss modulus reveals the information about liquid-like behaviour of the material, their viscous response which is associated with the sample’s heat energy dissipation. The complex modulus as ratio of loss and storage modulus is known as a loss factor or damping factor, indicating the material’s resistance to deformation [ 36 , 37 ].…”

Sustainable Strategy for Algae Biomass Waste Management via Development of Novel Bio-Based Thermoplastic Polyurethane Elastomers Composites

This work concerns the waste management method of algae biomass wastes (ABW). For this purpose, we prepared bio-based thermoplastic polyurethane elastomer (bio-TPU) composites. Algae biomass wastes are derived from algal oil extraction of Chlorella vulgaris and from biomass of Enteromorpha and Zostera marina. ABWs were used in the bio-TPUs composites as a filler in the quantity of 1, 5, 10, and 15 wt.%. The bio-based composites were prepared via the in situ method. Polymer matrix was synthesized from a bio-based polyester polyol, diisocyanate mixture (composed of partially bio-based and synthetic diisocyanates), and bio-based 1,3 propanediol. In this study, the chemical structure, morphology, thermal and mechanical properties of prepared composites were investigated. Based on the conducted research, it was determined that the type and the content of algae waste influence the properties of the bio-based polyurethane matrix. In general, the addition of algae biomass wastes led to obtain materials characterized by good mechanical properties and noticeable positive ecological impact by increasing the total amount of green components in prepared bio-TPU-based composites from 68.7% to 73.54%.

“…The cure profile of the extracted natural adhesive between 150℃ and 215℃ is shown on Figure 2 below. This temperature range was chosen for this adhesive extract from Caesalipinia decapelata because it the ideal temperature that most natural adhesives show cure profiles [6]. The profile (Figure 2) shows a significant change in storage modulus though it initially starts to rise slightly, attributable to increase in viscosity within the sample as temperature rises.…”

Adhesives have for long been developed from plant and animal materials. This includes animal proteins like casein and plant materials such as starches and dextrin’s which form precursors to synthetic adhesives. In this work, the mechanical properties of the extracted, isolated pod latex/adhesive samples of the Caesalipinia decapelata species were investigated using the Dynamic Mechanical Analysis (DMA) to study cure behavior of the adhesive observed on application of stress over a range of temperatures. The cure properties of this natural adhesive were compared to commercially available adhesives.
