TL;DR: In this article, a compression-molded flat wheel comprising a gridded sisal hemp back cover and a grinding body is described, which is produced with a material consisting of hollow microspheres, abrasive and binder.
Abstract: The invention discloses a compression-molded flat wheel comprising a gridded sisal hemp back cover. The compression-molded flat wheel comprises the gridded sisal hemp back cover and a grinding body, and the grinding body is produced with a material consisting of hollow microspheres, abrasive and binder. By regulating the usage of the hollow microspheres and the abrasive, the grinding effect of the compression-molded flat wheel can be regulated.

TL;DR: In this paper, the authors used maleic anhydride-grafted polypropylene to improve compatibility between fibres and poly-propylene, which resulted in increased tensile strength, flexibility, and impact strength.
Abstract: Due to their low weight, high specific strength, and low environmental impact, sisal fibre-polypropylene composites have gained popularity. However, the material has a low modulus and poor moisture resistance, among other shortcomings. This study investigated how flax fibre hybridization affects the physical parameters of sisal fibre-polypropylene composites. We used maleic anhydride-grafted polypropylene to improve compatibility between fibres and polypropylene. Adding flax fibres to polypropylene-silica composites resulted in increased tensile strength, flexibility, and impact strength, according to researchers. Water resistance was further improved by adding flax fibres. Tensile strength values of polypropylene-sisal fibre composites filled with 0, 5, 10, 15, and 20 wt% of flax fibres were 29.46, 30.56, 31.57, 33.12, and 34.64 MPa, respectively.

TL;DR: In this article , the synergic effects of alkaline activation and fibre inclusions, on the mechanical behaviour of fly ash stabilized black cotton soil was investigated, and the results conclusively showed that the alkaline activated-fly ash treated-sisal fibre reinforced soil exhibits better mechanical behaviour in terms of peak stress and post-peak behaviour and appreciable resistance to swelling.
Abstract: In this study, the synergic effects of alkaline activation (AA) and fibre inclusions, on the mechanical behaviour of fly ash stabilized black cotton soil was investigated. The natural fibre used in this research was treated with Sodium Hydroxide (NaOH) solution as an expedient solution to attain durability. The fibres are added in two forms: discrete fibres and geotextile. Assessment of engineering behaviour of the AA-treated soil reinforced with surface coated sisal fibres was carried out by conducting various laboratory tests like Free Swell (FS) test, Unconfined Compressive Strength (UCS) test, and cyclic triaxial test. Microstructural characterization was done by Scanning Electron Microscope (SEM) analysis and Fourier Transform Infra-Red (FTIR) spectroscopy analysis. The test results conclusively showed that the alkaline activated-fly ash treated-sisal fibre reinforced soil exhibits better mechanical behaviour in terms of peak stress and post-peak behaviour and appreciable resistance to swelling. Overall, the study shows that fibre-reinforced AA-fly ash amendment could effectively enhance the strength, stiffness and toughness of the soil and could subsidize the anticipated detrimental effects that could cause by dynamic loading. This study affirms the potential of alkali-treated sisal fibre as an alternative to traditional stabilizers for construction involving expansive soil.

TL;DR: In this paper, a study was done to determine the feasibility of modifying the behavior of open graded asphalt (OGA) concrete mix through the use of sisal fiber and waste plastics.
Abstract: To investigate the behavior of sisal fibre and waste plastic modified asphalt concrete mixes, a study was done to determine the feasibility of modifying the behaviour of open graded asphalt (OGA) concrete mix through the use of sisal fiber and waste plastics. The main objective of this research was to analyze and study how sisal fibre and waste plastics can be used to reduce bitumen drain down and effectively utilize waste plastics in construction of flexible pavement to improve on strength. A thorough study was done on the methodology of using locally-available waste plastics and sisal fibre as stabilizer and present the various tests performed on aggregates, bitumen and asphalt concrete. Aggregates sizes 12/6 mm and 2-3 mm size of waste plastics were heated and mixing done until plastics melted and coated aggregates. Thereafter, sodium hydroxide (NaOH) treated sisal fibre, shred into 5 mm long threads was mixed with hot bitumen and coated hot aggregates at specified temperature. The resultant mix was analyzed for bitumen retention properties to assess its suitability for road construction. Using Marshall procedure, optimum sisal content (OSC) was 0.3% and optimum plastic content (OPC) was 5% for modified asphalt concrete mixes prepared using optimum binder content (OBC) of 5.5%. It was established that bitumen drain down of Sisal-Plastic modified samples was 0% while nonmodified samples had bitumen drain down of 6.5%. The use of this innovative technology will strengthen the road construction industry as well as help to improve the environment. This would further their successful application as construction material in flexible pavement to improve road performance.
