Concrete nuclear reactor vessels, of the order of magnitude of 15-m (50-ft) inside diameter and length, have inner linings of steel which confine the pressure. After fabrication of the liner, the tubes for the cables or wires are put in place and the concrete is poured. High-strength reinforcing steel is used. Because there are thousands of reinforcing tendons in the concrete vessel, there is a statistical factor of safety. The failure of 1 or even 10 tendons would have little effec t on the overall structure. 

Plates and pipe inside these vessels must be of heavy design and welded (not bolted) to the vessel itself. Otherwise, vibration forces within the vessels and piping can create fatigue cracks and equipment feilure. Figure 13-26. Even if applicable vessel codes do not require such strength reinforcement, it is advisable for the designer to insist on these extra rugged details. 

Lower-aspect ratio for automobile tires, higher load-carrying capacity, and reduced size for tmck tires would be key sectors for development. Farm and off-road tire will face demand for higher speeds, more ride comfort, and enhanced traction. Development of advanced higher-strength reinforcement will lead to lower weight and reduced thickness for the tire. 

Table 3.4 shows some examples of the modulus and the strength reinforcement ratios for various reinforced thermoplastics and thermosets. The reinforcement ratio is the performance of the reinforced polymer divided by the performance of the neat polymer.

Selection of a consolidant and engineering its properties (viscosity, temperature, and polymerization time) are based on analysis of the artifact, the level of degradation, and the materials that will provide transition and strength-reinforcement properties. 

A ceramic test rig for biaxial measurement (ball-on-ring) has been developed to accommodate a variety of different pellet sample dimensions from 21 to 28mm diameter inclusive. This was achieved by manufacturing a number of fittings as seen in Fig. 3 from a ceramic matrix composite material (Zircar RSLE 57), which is a low expansion high strength reinforced silica matrix composite product designed for use with temperatures up to 1100°C.

Fibers are delivered as pulps, which are chopped and refined hhers with a high surface area. The pulps are used as specialty additives that enhance performance hy providing excellent reinforcement. Lightweight strength reinforcement can he achieved with continuous filaments. Honeycomb cores are available for aerospace industries. Spun yarn is used for protective coatings. ...
