The enhancement of many of the mechanical properties of thermoplastics which may be achieved by orienting the molecules has been known for some time. It has been exploited in the production of textile fibres end oriented ...

Part 1 General Developments The basic development work on the tensile creep apparatus was completed by March, 1968. A description of the latest 'heavy-duty' creep rig and two types of contraction extensometer, together ...

Short fibre reinforced thermoplastic pipe was produced by an extrusion process which oriented the fibre reinforcement predominantly into the pipe hoop direction. The fibre reinforcement was thereby used to maximise ...
