... Table B.l Properties of Polymers ADVANTAGES CONCERNS High strength and stiffness/weight ratio Corrosion-resistance Low signature Manufacturing flexibility Variety of properties Flexibility Chemical stability Low cost Survivability in combat Flammability and flame spreading Release of smoke and toxic gases Long-term durability Repair problems (i.e., joints) Resistance to high temperatures The Navy also makes use of polymers in more critical and demanding applications, such as in load-bearing polymeric matrix composites, special coatings for signature control, coatings for corrosion reduction in waste-holding tanks, fuel storage tanks, and metal pipe linings, and so on, where polymers are often applied as part of a technology package to meet the needed performance criteria.

... A successful use of advanced composites in more critical load-bearing shipboard structures will likely pose many scientific as well as technological challenges, including the further improvement of existing manufacturing methods as well as the development of new ones. In addition, there is a great need to supplement laboratory testing of potentially useful composite structures by realistic on-board evaluation using vessels dedicated for such purposes.
