摘要: A polyolefin plaque is produced by hot compaction of an assembly of melt spun oriented fibres. It has been found that good compaction can be achieved at relatively low compaction pressures, less than 10 Pa. Compaction can be carried out in an autoclave, rather than in a hot compaction press, and the mechanical properties of plaques so produced range from good to excellent.

摘要: A polyolefin plaque is made by hot compaction of an assembly of fibres of the oriented polymer. It has been found to be beneficial to subject the fibres to a prior crosslinking process. Hot compaction is then less temperature-sensitive and produces plaques with excellent hot strength properties. Preferably the fibres have been subjected to prior stages of irradiation and annealing, both in a non-oxidising environment, for example acetylene.

摘要: A process for the production of a polymeric article comprises: (a) forming a ply having successive layers, namely, (i) a first layer made up of strands of an oriented polymer material; (ii) a second layer of a polymeric material; (iii) a third layer made up of strands of an oriented polymeric material, wherein the second layer has a lower peak melting temperature that of the first and third layers; (b) subjecting the ply to conditions of time, temperature, and pressure sufficient to melt a proportion of the fits layer, to melt the second layer entirely, and to melt a proportion of the third layer, and to compact the ply; and (c) cooling the compacted ply. The resultant articles have good mechanical properties yet may be made at a lower compaction temperature than articles not employing the second layer, leading to a more controllable manufacturing process.

摘要: Polymeric monoliths having high stiffness and strength can be produced by heating an assembly of polymer fibres under a contact pressure to a temperature at which a proportion of the fibre is selectively melted and then compressing the assembly. Preferably at least 5% of the polymer is melted so that on compression the molten materials fills the voids within the assembly. The use of polyolefin fibres especially melt spun polyethylene fibres is preferred. The products are useful e.g. as orthodontic brackets, bone prostheses and in body armour.
