uhmwpe fiber is processed by gel spinning because its melt viscosity is extremely high. the productivity of gel spinning is very low and the solvent extraction is another annoying issue, especially when toxic solvents are involved.
to reduce the uhmwpe melt viscosity using some processing agents but not to decrease the fiber property has attracted tremendous invesitagtions, but such a fiber is not availabe yet.
what are the merits of uhmwpe fiber?
light, strong, tough, hydrophobic, wear resistant, chemical resistant, low temperature sustainability, biocompatible, notch insensitivity, etc
what are the disadvantages?
low melting point, high viscosity, low creep performance, low adhesion
what kind of materials can solve the problems without compromise the merits of uhmwpe fiber?
Everything, Nothing ...
