A Review of Sisal Fiber-Reinforced Geopolymers: Preparation, Microstructure, and Mechanical Properties

Molecules
The early strength of geopolymers (GPs) and their composites is higher, and the hardening speed is faster than that of ordinary cementitious materials. Due to their wide source of raw materials, low energy consumption in the production process, and lower

Experimental investigation on mechanical behavior of sands treated by enzyme-induced calcium carbonate precipitation with assistance of sisal-fiber nucleation

Frontiers in Earth Science, 2022
Sisal fibers had obvious advantages of mechanical strength on reinforced enzyme-induced calcium carbonate precipitation (EICP)-cemented loose sands. However, there are few related researches, whose research on strength and toughness is not sufficient ...

The impact of fire on habitat use by the short-snouted elephant shrew ('Elephantulus brachyrhynchus') in North West Province, South Africa [PDF]

, 2008
Several studies have investigated the response of small mammal populations to fire, but few have investigated behavioural responses to habitat modification. In this study we investigated the impact of fire on home range, habitat use and activity patterns

Canola Fiber as Reinforcement for Composites: Effect of Fiber Extraction and Processing Method on Fiber Properties, Nonwoven Manufacturing, and Composite Properties

Polymer Composites, EarlyView.
Comparison of canola fiber reinforced composites manufactured using water‐retted, field‐retted, and enzyme‐treated fibers. ABSTRACT Canola fibers obtained from discarded stalks through various processing methods, including water‐retting and field‐retting followed by mechanical decortication and enzymatic degradation, were utilized as discontinuous ...

Exploring biofiber properties and their influence on biocomposite tensile properties

Polymer International, EarlyView.
The study measured the physical, flow and chemical properties of 10 biofibers. It characterized the tensile properties of derived biocomposites and linked them using regression models, showing robust predictive performance. Abstract Biofibers serve as effective reinforcements for neat polylactic acid (PLA) in biocomposites, offering an attractive ...
