    Abstract: The invention relates to a gel-spun fiber comprising an ultra-high molecular weight polyethylene (UHMWPE), wherein the UHMWPE has an intrinsic viscosity (IV) of at least 4 dL/g and comprises at least 0.3 short chain branches per thousand total carbon atoms (SCB/1000TC), characterized in that the fiber further comprises between 0.1 and 10 parts by weight of carbon black based on 100 parts by weight of the amount of the polyethylene forming the fiber. The invention further relates to a yarn comprising at least 5 such gel-spun fibers as well as to articles comprising said fibers or yarns.

    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.
