چکیده

Results of an investigation of the mechanical performance of injection moulded long glass-fibre reinforced polyamide 6,6 composites are presented. The glass-fibre content in these composites was varied over the range of 10-50% by weight using fibres with average diameters of 10, 14 and 17 μm. Impact testing was carried out at -40, 23 and 80°C on dry-as-moulded and boiling water conditioned samples. The results from these long fibre composites are compared with standard extrusion compounded short glassfibre materials. Data on the influence of fibre diameter, fibre concentration, residual fibre length, hydrothermal conditioning and testing temperature on the composite performance in notched and unnotched pendulum impact tests and multiaxial instrumented impact tests are presented and discussed. All of the above parameters are shown to have significant influence on impact performance. However, the level of these effects is shown to depend on which type of impact test is being considered.

The influence of fibre length, diameter and concentration on the strength and strain to failure of glass-fibre reinforced Polyamide 6,6

Results of an investigation of the mechanical performance of injection moulded long glass fibre reinforced polyamide 6,6 composites are presented. The glass fibre content in these composites was varied over the range 10-50% by weight using fibres with average diameters of 10, 14, and 17 micrometres. Mechanical testing and analysis of the apparent interfacial shear strength was carried out at 23...

Fibre Orientation at Notches and Fatigue Behaviour of Short Fibre Reinforced Polyamide

Fatigue strength of injection moulded short fibre reinforced polymer components depends upon fibre orientation with reference to the acting stresses. For the case of a short glass fibre reinforced (SGFR) polyamide 6, this dependence was expressed through a relationship derived from the Tsai-Hill criterion [1], with the strong assumption that fibres were parallel to each other. This relationship...
