“…and sustainable fibers such as wool [18,19] might further improve the utility and sustainability profile of these materials. The bundled protein microfibriles surrounded by the wool cuticle are known to give strength to the fiber, which may be imparted to composites containing wool.…”

“…[12] To reinforce the polymer, unprocessed wool was used directly in the composite synthesis. [18,19] This strategy provided a material with greater tensile strength, reduced thermal conductivity, and greater flame resistance relative to the base polymer. The composite obtained is therefore a promising material for energy saving insulation and is made from low-cost, abundant, and sustainable feedstocks.…”

Insulating Composites Made from Sulfur, Canola Oil, and Wool**

An insulating composite was made from the sustainable building blocks wool, sulfur, and canola oil. In the first stage of the synthesis, inverse vulcanization was used to make a polysulfide polymer from the canola oil triglyceride and sulfur. This polymerization benefits from complete atom economy. In the second stage, the powdered polymer is mixed with wool, coating the fibers through electrostatic attraction. The polymer and wool mixture is then compressed with mild heating to provoke S--S metathesis in the polymer, which locks the wool in the polymer matrix. The wool fibers impart tensile strength, insulating properties, and flame resistance to the composite. All building blocks are sustainable or derived from waste and the composite is a promising lead on next--generation insulation for energy conservation.

Effect of Short Fiber Reinforcements on Fracture Performance of Cement-Based Materials: A Systematic Review Approach

2021

View full text Add to dashboard Cite

Fracture characteristics were used to effectively evaluate the performance of fiber-reinforced cementitious composites. The fracture parameters provided the basis for crack stability analysis, service performance, safety evaluation, and protection. Much research has been carried out in the proposed study field over the previous two decades. Therefore, it was required to analyze the research trend from the available bibliometric data. In this study, the scientometric analysis and science mapping techniques were performed along with a comprehensive discussion to identify the relevant publication field, highly used keywords, most active authors, most cited articles, and regions with largest impact on the field of fracture properties of cement-based materials (CBMs). Furthermore, the characteristic of various fibers such as steel, polymeric, inorganic, and carbon fibers are discussed, and the factors affecting the fracture properties of fiber-reinforced CBMs (FRCBMs) are reviewed. In addition, future gaps are identified. The graphical representation based on the scientometric review could be helpful for research scholars from different countries in developing research cooperation, creating joint ventures, and exchanging innovative technologies and ideas.

“…It has recently been established that judicious selection of fillers and crosslinkers can improve the mechanical performance of sulfur polymers and related composites. 10--14 We considered that preparing composites from sulfur polymers and natural and sustainable fibers such as wool 15,16 might further improve the utility and sustainability profile of these materials. We were also motivated to explore the polymer made from sulfur and canola oil because it can be prepared on multi--kg scale 17 and it is derived from low--cost and sustainable building blocks.…”
