A solution to this issue is the production of bio-based composites to partially replace the PLA matrix with industrial wastes characterized by a zero-cost, e.g., linoleum, to also valorize them in a circular economy perspective. Linoleum heterogeneous nature deriving from the simultaneous presence of lignocellulosic and inorganic fillers and oil/rosin binders, made the evaluation of matrix/filler compatibilization strategies necessary. Two approaches were considered, one from the filler perspective with NaOH and silane treatments, and the other one from the matrix perspective by adding a chain extender (C.E.).

Considering this, the costs and disposal of the chemicals and the increased environmental impact of the process, this approach was discarded. One the contrary, the introduction of C.E. does not modify the manufacturing process and increases tensile stiffness and elongation at break of 7.2 % and 415.5 % compared to neat PLA with a tolerable reduction in strength, i.e., 16.6 %, thus being a suitable way to exploit linoleum as zero-cost filler.</p></div>","PeriodicalId":20628,"journal":{"name":"Polymer Testing","volume":"138 ","pages":"Article 108548"},"PeriodicalIF":5.0,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0142941824002253/pdfft?md5=25bec655aac1a0971ecab66c8b74882a&pid=1-s2.0-S0142941824002253-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142044495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study establishes an energy-based evolution mechanism for the compressive failure modes of plain weave composite materials as the strain rate varies. This mechanism illustrates how the rate dependency of failure modes arises from the competitive relationship between strain potential energy and deformation kinetic energy. At low loading rates, the specimen exhibits a progressive crushing failure mode characterized by low peak stress and significant geometric deformation. As the loading strain rate increases, the energy required for this geometric deformation also increases. When the energy expenditure surpasses that needed to elevate the stress level of the specimen, it transitions to an instantaneous failure mode with high peak stress. In this mode, the specimen fractures into multiple small fragments immediately upon failure, lacking the large geometric deformations observed at lower rates. Through calculating this energy mechanism, a transition strain rate of 180 s<sup>−1</sup> was determined for both failure modes. The accuracy of this mechanism was further verified by tests conducted near the critical strain rate. The energy-based evolution mechanism for failure modes provides a simplified and concise framework for simplifying complex models of composite material failures.</p></div>","PeriodicalId":20628,"journal":{"name":"Polymer Testing","volume":"138 ","pages":"Article 108538"},"PeriodicalIF":5.0,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0142941824002150/pdfft?md5=5c3ea24ba2c7cf921d88afe56edee3ab&pid=1-s2.0-S0142941824002150-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142012885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The contact with the respective fuels raises questions concerning material compatibility as biodiesel exhibits significant differences compared to conventional diesel fuel affecting its sorption and plasticization behavior in polyethylene. In this study, its behavior with respect to environmental stress cracking, considered one of the most frequent damage mechanisms leading to failure of polymer parts and packaging, was evaluated using the well-established Full Notch Creep Test. This approach allows for a detailed fracture surface analysis using imaging techniques, such as optical and laser scanning microscopy, as well as infrared spectroscopy. Comparing the environmental stress cracking behavior in standard surfactant solutions with that in biodiesel and diesel, respective crack propagation rates, showing different levels of acceleration, were determined and details of the underlying mechanisms could be revealed.
