2. Commercial fishing

Performance advantages of spectra cited above related to decelerator systems are equally applicable to commercial fishing applications. In addition, Spectra products have a natural buoyancy and float, whereas polyesters and steel wire products do not.

Spectra’s superior strength greatly reduces bulk for rib lines. Head ropes, bridles, and other ropes traditionally made from polyesters or other synthetic fibers. Unlike wire rope, spectra will not corrode and damage netting materials over time. Also, regardless of their size, ropes made with spectra float, which significantly reduces the need for bulky and expensive flotation devices. Spectra winch lines, lifting slings and high strength chokers allow for easy handling and and greater safety when hauling back and unloading. Spectra provide the same strength as wire rope at only 20% of the weight. This reduces bodily strain when lifting and allows more crew efficiency, especially in emergency situations.

3. Damage-Tolerant Radar Domes

Radar domes, in addition to having demanding electrical requirements, must often exhibit a high degree of structural integrity. The composite structural properties have to be tailored to the specific application. For example, radomes may require high impact tolerance, a high degree of stiffness, and/or high tensile strength. The use of higher frequency radars (even into the millimetric band) has resulted in a growing interest in spectra systems. Three main factors, known as the radome parameters, control the microwave transparency: dielectric constant, loss tangent, and dielectric material thickness. The first two are properties inherent to main constituents of the radome (i.e., the main forcing fiber and the resin); the third is a geometric variable of the radome wall design.

CONCLUSION

The Emerging Paradigm The essence of new product development in fiber science during the 20th century has followed a relatively narrow and perhaps limited route of development. Fibers are made from either condensation or addition-type polymer platforms. The fiber may have polymer modifications, contain additives or be altered on the surface.

The next century, however, will demonstrate the seemingly unlimited power of the synergy of diverse disciplines as borders between material science, biological science and information science blur and erode Today the breadth of complementary technologies is far greater. In the future fiber molecules will be designed, engineered and produced more efficiently than ever before due to advances in combinatorial chemistry, robotics, nanotechnology, bioinformatics, spectroscopy, and high-throughput screening.
