Textile reinforcement

The trade name of a polyester fibre used as textile reinforcement for mbber in products such as tyres, belting and hose. It is a truly synthetic fibre made from polyethylene terephthalate, a condensation product of terephthalic acid and ethylene glycol. 

Rubber in tubular form such as gas tubing. Tubing differs from hose in that it has no structural textile reinforcement. 

In most modem pneumatic tyres the textile reinforcement is in the form of steel wire constmcted in the manner of cord fabric.

Amongst others, the advantage of such an absorbant lies in the excellent structural properties conferred by the composite material (glass textile reinforcement coated with polyaniline-F epoxy matrix). Besides, this composite can be combined with other materials with which its mechanical and radioelectric properties are compatible (foams, honeycombs...), For example, a bandwidth at — lOdB between 5 and 20 GHz was obtained by adding only 4-5 kg/m to the starting composite material. 

The measurement of compressive properties of plastics is covered by ISO 604 [44]. Unlike with the tensile test a single document is able to cover a wide range of materials, since test geometries and other conditions tend to be less variable between types of plastic than is the case for tensile testing. Nevertheless, there arc types of materials that the standard does not purport to cover, and these include textile reinforced plastics, cellular materials, and sandwich constructions involving cellular materials.

In this section we select the most important criteria of correspondence of a model to reality. Then, we overview both the peculiarities of textile reinforcement that must be accounted in an ideal damage model and the requirements to the solid models asserted by various FE approaches. Meso-scale 3D FE models available in literature are classified according to the selected geometric features. Models of 2D braided composites are included in the overview to give a wider perspective. In many aspects, challenges for modelling 2D braided and 2D woven yam architectures are exactly the same. 

All these mechanical results demonstrate the ability of 3D woven fabrics to be adjusted to requirements and cover a wide range of mechanical properties by modifying weaving or manufacturing parameters such as spacing between yams or fibre volume fraction of the composite. Databases of materials can be built in order to help design or selection of these 3D textile reinforced composites.

Due to the complex nature of the textile reinforcement since air can become entrapped in the interstices of the fabric structure. This can be particularly evident when coarse yams (or tows) are used or in complex three-dimensional (3-D) stmctures, e.g. braided or woven, and may be most prevalent at the tool/composite interface.

Production process of tailor-made reinforcement. The textile reinforcement structures were coated with an epoxy resin. According to the production process, the coating and curing of planar and spatial reinforcements have to be separated.

While the increase in the flexural strength is desirable due to the oscillating motion of the steel tower, the integration of textile reinforcement remains necessary in order to absorb the tensile stresses.
