Geotextiles mechanical properties

Olefin fibers are used for a variety of purposes from home furnishings to industrial appHcations. These include carpets, upholstery, drapery, rope, geotextiles (qv), and both disposable and nondisposable nonwovens. Fiber mechanical properties, relative chemical inertness, low moisture absorption, and low density contribute to desirable product properties. Table 7 gives a breakdown of olefin fiber consumption by use (73—75). Olefin fiber use in apparel...

UV-radiation and abrasion. However, it is stUl not clear whether it may cause serious changes or detrimental effects on the mechanical properties of the geotextile over lifetime. 

Evidently, there are three important mechanical properties of a geotextile used for reinforcement tensile modulus, tensile strength, and surface friction. The puU out test is a common one for determining the strength and deformation parameters between the reinforcement and the soil in the design of reinforced earth stmctures (Adanur ... 

Mechanical properties of geotextiles are basic properties related to applications where the geotextiles is required to bear a load or to undergo a deformation.

Geotextiles offer various properties that we can categorize into three main families the physical properties refer to the dimensional characteristics of the product. Mechanical properties refer to the behaviour of the geotextile when it is subjected to mechanical constraints. Hydraulic properties describe the behaviour of the geotextile in the presence of liquids or gases. The key properties of geotextiles are defined in Table 3.2. 

The impact of the manufacturing process on the geotextile s mechanical properties is easily demonstrated with a standard stress—strain curve. Fig. 3.1 shows that the different types of geotextiles have a greatly differing behaviour under strain.
