As compared to laminated composite, there is no doubt that the impact tolerance of the 3-D woven fabric reinforced polymer composite has been enhanced dramatically due to the 3-D network structme and the improved transverse shear resistance. However, it is clear that even repeated low velocity impact can cause significant damage. Therefore, tike laminated composite and sandwich composite, 3-D woven fabric reinforced polymer composite also calls for self-healing capabilities.

Next, we will present applications of the CTH scheme in several real-world composite stractures. They arc fiber reinforced syntactic foam cored sandwich structures, sandwich stractures with a continuous fiber reinforced grid stiffened syntactic foam core, and 3-D woven fabric reinforced polymer composite structures. Of course, the core or the polymer composite is based on the same thermosetting PSMP as discussed above. 

The 3-D woven fabric reinforced foam composite panel was fabricated in a steel mold using a gravity assisted method by impregnating the 3-D woven fabric with the uncured foam. The... 

Fiber reinforced thermosetting polymer composites have been used in the form of laminate, sandwich, grid stiffened, stitched, Z-pinned, three-dimensional (3-D) woven fabric, and hybrid structures. In addition to carrying the designed static/dynamic loads, most composite stmcmres experience some kind of low or high velocity impact incidents during their life cycle. A low velocity impact is not uncommon. For example, dropping a tool on to a composite stmcmre...

Three-dimensional (3-D) fiber reinforced polymeric materials have been shown to have a good impact tolerance [108,109], making them attractive candidates in weight sensitive industries such as in aerospace, auto, and maritime. A number of stodies have been conducted to understand the impact response of 3 -D woven composites [ 108,109]. For example, B aucom, Zikry, and Rajendran [110] investigated the effects of fabric architecture on damage progression, perforation resistance, strength, and failure mechanisms in composite systems of... 

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.

The precursor fiber type for reinforcing the carbon matrix can be an oxidized PAN fiber (opf), or either a PAN or pitch based carbon fiber. In some instances, for special applications, such as the Shuttle, a cellulose based carbon fiber is used. The reinforcements can be unidirectional have a random chopped fiber presentation as in a felt format a woven product from continuous fiber presented in a 2D, 3D, or in a Multi-D format (Section 21.1), or a non-woven carbon fiber. The chosen fiber architecture is most important for a given application and Lei et al [4] describe how, for example, 3-D braiding can be applied to carbon-carbon composites. One of the early forms of near net shape reinforcement used for carbon-carbon aircraft brakes was based on a weft knitted 3-D fabric made by the Pressure Foot process (Figure 14.1).
