STRUCTURES COMPRISING POLYMERIC FIBERS
Abstract:
The present invention relates a structure comprising rigid elements connected together by interconnecting elements in such a way to form a statically determined or statically over-determined structure, wherein said structure comprises at least one tension element comprising polymeric fibers having a stabilizing creep of at least 0.3% and at most 10% and a minimum creep rate lower than 1×10−5% per second, said stabilizing creep and minimum creep being measured at a tension of 900 MPa and a temperature of 30° C. The present invention also relates to said structure being a framing structure, preferably a space frame; a suspended body; a platform, preferably a marine platform; or a wheel comprising spokes. Furthermore, the invention relates to the use of polymeric fibers having a stabilizing creep of at least 0.3% and at most 10% and a minimum creep rate lower than 1×10−5% per second, said stabilizing creep and minimum creep being measured at a tension of 900 MPa and a temperature of 30° C. for a statically determined or statically over-determined structure, preferably for a framing structure, such as a space frame; for a suspended body; for a platform, preferably for a marine platform; or for a wheel comprising spokes.
