Geosynthetic reinforced capping of highwater content waste materials is becoming an efficient and economic way of dealing with the confinement of the contaminants. To define the filtration performance of sludge-geotextile systems and investigate their durability, ten sludge lagoon test cells were constructed using of a lightweight fill, i.e. a wood chip/soil mixture over different geotextiles. ...

An activated carbon fiber nonwoven (ACF) was manufactured from a cotton nonwoven fabric. For the ACF acoustic application, a nonwoven composite of ACF with cotton nonwoven as a base layer was developed. Also produced were the composites of the cotton nonwoven base layer with a layer of glassfiber nonwoven, and the cotton nonwoven base layer with a layer of cotton fiber nonwoven. Their noise abs...

The objective of this research was to analyse the tensile response three geosynthetics, apply constitutive equations, and propose values for model parameters represent nonlinear behaviour these materials in short-term, supported by statistical analysis. Data specimens a nonwoven geotextile, woven geogrid reinforcement geocomposite previously submitted mechanical damage, abrasion damage followed...

Geotextiles have been commonly used in geotechnical and environmental engineering projects to prevent erosion of soils in contact with the filter without impeding the flow of seeping water through the soil. Several empirical criteria incorporating varying factors of safety have been proposed for selection of geotextile filters. A probabilistic numerical filter model, named RETAIN, using image-b...

A solution blow spinning technique is a method developed recently for making nonwoven webs of micro- and nanofibres. The principal advantage of this method compared to a more traditional electrospinning process is its significantly higher production rate. In this work, the solution blow spinning method was further developed to produce nonwoven polymeric scaffolds based on a copolymer of tetrafl...

The aim of this study is to develop a process to produce high-performance cement-based composites reinforced with flax nonwoven fabrics, analyzing the influence of the fabric structure-thickness and entanglement-on mechanical behavior under flexural and tensile loadings. For this purpose, composite with flax nonwoven fabrics with different thicknesses were first prepared and their cement infilt...

Geotextile and gravel pads offer a low-cost alternative to concrete for providing all-weather surfaces for cattle and vehicle traffic, and are used in many livestock facilities to minimize mud, runoff and erosion of heavy traffic areas. The objective of this study was to compare different combinations of geotextile and gravel used in heavy livestock traffic areas that minimize the potential for...

The purpose of this research was to enhance the stab resistance of protective clothing material by developing a new high-density nonwoven structure. Ice picks often injure Japanese police officers due to the strict regulation of swords in the country. Consequently, this study was designed to improve stab resistance against ice picks. Most existing anti-stab protective clothing research has focu...
