The hot compaction of high modulus melt-spun polyethylene fibres

The production of solid section highly-oriented polyethylene by compaction of melt-spun polyethylene fibres is described. Differential scanning calorimetry, X-ray diffraction, and electron microscopy have been used to determine the structure of the compacted polymer. The essential feature of the pro...

Description
Summary:The production of solid section highly-oriented polyethylene by compaction of melt-spun polyethylene fibres is described. Differential scanning calorimetry, X-ray diffraction, and electron microscopy have been used to determine the structure of the compacted polymer. The essential feature of the process is shown to be selective surface melting of the fibres to form a polyethylene/polyethylene composite of very high integrity, yet maintaining a very high proportion of the strength and stiffness of the fibres.
