Uneven surfaced hollow fabrics

Figure 3.1 Illustration of a hollow fabric with uneven surfaces, (a) Fabric construction, (b) Cross section of the fabric.

In general, a hollow woven fabric refers to one whose cross sections are porous. The materials between the two surfaces could be interlaced fabrics or simply yams and fibres. Under this definition, the hollow fabrics can be classified into hollow fabrics with uneven surfaces and those with flat surfaces. [Pg.81]

Figure 3.3 shows resin-treated hollow fabrics with flat and uneven surfaces. The hollow fabric with uneven surfaces can be used in curved and flat forms, whereas the hollow fabric with flat surfaces can only be used as a board stmcture. [Pg.82]

Usually, hollow woven fabrics are woven with the tunnels in the weft direction. However, hollow fabric with uneven surfaces can also be made in the warp direction for applications in which long tunnel length is necessary, whereas hollow fabric with flat... [Pg.82]

Use of the hollow structure in the in-plane directions offers high capacities in impact energy absorption and in impact force attenuation. This is suitable for areas where damping and protection against impact are of importance. Packaging and personal and property protection are possible areas for application. There has been work on using hollow composites reinforced by 3D hollow fabrics with uneven surfaces for limb protection against trauma impact (Yu and Chen, 2004). [Pg.102]
