TL;DR: In this paper, a method for preparing sisal hemp modified asphalt from SBS grafted sisal-hemp fiber is presented. But the method is not suitable for use in the manufacturing process.
Abstract: The invention discloses a method for preparing sisal hemp modified asphalt from SBS grafted sisal hemp fiber. The method comprises the following steps: (1) crushing sisal hemp fiber, soaking in a NaOh solution, washing, and drying; (2) mixing pure chemical tetrahydrofuran and pure chemical N,N-dimethylformamide at the mass ratio of 3:1; (3) dissolving a styrene-butadiene-styrene segmented copolymer, that is, SBS, into a mixed solution; (4) adding the sisal hemp fiber, further adding a benzoyl peroxide initiator which accounts for 1% of the mass of the sisal hemp fiber to react for 2 hours, depositing the sisal hemp fiber by using absolute ethyl alcohol, and drying, thereby obtaining SBS grafted sisal hemp fiber; (5) by taking grade-A #70 pavement petroleum asphalt as a raw material, doping the SBS grafted sisal hemp fiber which accounts for 8% of the mass of the asphalt at 150-160 DEG C, uniformly mixing, and leaving to stand for 12-16 hours. The raw materials are cheap and easy to obtain, the sisal hemp modified asphalt is simple to prepare, convenient to machine and form and environment-friendly and non-toxic, and the strength of asphalt is improved as the interface bonding force of the sisal hemp fiber and the asphalt in the composite material is greatly improved.

TL;DR: In this article , a facile hybridization of sisal/coconut palm reinforced epoxy composite, is presented, where the fabrication method involved the use of hand lay-up techniques.
Abstract: In this study, a facile hybridization of sisal/coconut palm reinforced epoxy composite, is presented. The fabrication method involved the use of hand lay‐up techniques. The results of the fabricated composites were investigated by using the universal testing machine, hardness testing machine, scanning electron microscope, and an impact testing machine. In order to obtain optimize results for the tensile, flexural, and impact strengths of the fabricated samples, the fabrication procedures involved varying the volume fractions of sisal and coconut palm hybrid with different compositions. The maximum tensile, flexural, and impact strengths measured for the fabricated fiber/polymer composite, are: 45 MPa, 90 MPa, and 38.9 kJ/m2. The scanning electron microscopy (SEM) and energy dispersive x‐ray spectrometry (EDS) of the composites showed that the composites with equal volume fractions of sisal and coconut palm fiber exhibited better performance and better mechanical properties. Furthermore, the improved mechanical properties such as hardness, tensile strength, flexural strength and impact strength were obtained with fibers of longer length. By considering the excellent mechanical properties of the fabricated composite, it is envisaged that the composite be suitable for the manufacturing of helmet, automobile and train coach interiors.

TL;DR: In this paper , the effects of sisal fiber when it is chemically treated and infused with concrete, comparing it to ordinary concrete in strength tests is described. But, the results showed that the results were limited to the M30 concrete grade.
Abstract: Concrete with fiber as a reinforcing material is one of the important fields of research that is gaining traction in this upcoming green technology revolution. By adding fibers to concrete, the tensile strength properties are vastly improved without compromising the strength characteristics, and cost fluctuation is minimal. This research is being carried out to improve the qualities of concrete that have been infused with chemically treated sisal fiber in varied ratios. The paper investigates and describes the effects of sisal fiber when it is chemically treated and infused with concrete, comparing it to ordinary concrete in strength tests. Water absorption, workability, and other material characteristics of Sisal fiber reinforced concrete with 0.5 per cent, 1 per cent, 1.5 per cent, and 2 per cent fiber replacing cement by volume fraction and a sisal fiber aspect ratio of 1:100 are compared to the traditional M30 concrete grade. After being treated with an alkaline solution, 0.5 per cent and 1 per cent sisal fiber reinforced concrete increased tensile and compressive strength, as well as the formation of calcium carbonate deposits on the fiber interfaces; this also contributes to the concrete’s corrosion resistance and durability.

TL;DR: In this paper , the impact of alkaline treated sisal fibres with different combinations of Polyvinyl alcohol (PVA) fibres (Mix-1 is 2% sisal, Mix-2 is 0.5% PVA fibres) on the characteristics of Indian Zone II fine aggregates (50% river sand + 50% Manufactured sand) based ECC analyzed.
Abstract: Abstract Engineered Cementitious Composite (ECC) is one of the versatile building components. The characteristics of materials and curing period are major factors that will influence the eco-friendly nature, and performance of the composite. In this experimental analysis, the impact of alkaline treated sisal fibres with different combinations of Polyvinyl alcohol (PVA) fibres (Mix-1 is 2% Sisal fibres, Mix-2 is 0.5% Sisal fibres + 1.5% PVA fibres) on the characteristics of Indian Zone II fine aggregates (50% river sand + 50% Manufactured sand) based ECC analyzed. For this, high fly ash to Cement dosage (f/c) of 1.4 is considered. These sisal fibres and f/c ratio are responsible for reduction in the disposal (or) environmental problems. The compressive strength of composite slightly improved from Mix-1 to Mix-2 at 28days with the decreased content of sisal fibres. But the split tensile and flexural characteristics highly increased by 8.33%, 5.45% from Mix-1 to Mix-2, respectively. These characteristics highly improved with the increased curing period (28days to 120days). The durability of the composite significantly influenced from 28days to 56days, but slightly improved with the decreased content of sisal fibres. To analyze these characteristics, SEM and XRD analysis are performed. Portlandite and quartz content was highly reduced (formation of C-S-H gel) from 28days to 56days due to hydration of unhydrated fly ash, fine aggregates, and other materials. The microstructure of both the mixes is densified with this gel. Mix-2 is more densified than Mix-1 due to the properties and arrangement of sisal fibres. These fibres are appropriately arranged in the partial replacement of PVA fibres compared to full dosage.
