RIBONUCLEOSIDES FOR PREDICTION OF SKIN IRRITATION

Not Available During Phase I KCI will develop at least ten different candidate designs for a composite material bracing system that will prevent buckling of a seismic energy-absorbing steel cruciform member that the bracing system surrounds. KCI's new lightweight bracing, which is intended to replace the heavy concrete and steel system currently in use, will ensure that the energyabsorber is effective both in tension and compression. The lighter weight of the composite design will be a major advantage in retrofitting existing structures with inexpensive seismic protection devices. KCI designs will investigate a variety of geometric configurations. Reinforcing materials in the study will include E-glass, S-glass and Carbon, as well as a proprietary system that on paper offers significant performance advantages over traditional composite reinforcements for this application. Matrix systems will include polyester, vinyl ester, phenolic and epoxy. We expect pultrusion will be the manufacturing process of choice for this product, however in Phase I designs tailored for other processes including braiding, filament winding, SCRIMP and RTM will also be considered. In Phase I KCI will fabricate sample parts for testing by our program consultants in the MIT Civil Engineering Department. In addition, an innovative manufacturing concept will be developed and tested. BENEFITS: Seismic energy dissipation has become an important aspect of build design, however cost of the required earthquake prot
