Mechanical properties of glass fibre reinforced polypropylene thermoplastic pipesKareem, Yusuf Abiola 12 March 2008 (has links)
ABSTRACT
Glass fiber reinforced polypropylene pipes were fabricated from 6-10 layers of
“Plytron” GN638T 25mm wide glass fiber pre-impregnated polypropylene tapes
using filament winding/tape laying process, in-situ consolidation on a 1000mm long
mandrel. Infrared heater and heat gun were used in heating the incoming tapes and the
substrate at the nip point. The effects of process pressure and temperature on the
mechanical properties were investigated by testing samples of test laminates and
fabricated pipes for their mechanical properties. Results indicated that the mechanical
properties of the test samples and pipes were affected by changes in process
temperature and pressure, with an optimum process pressure and temperature being
16.8KPa and 2800C respectively. The cost analysis of the fabricated pipes indicated
that the materials and method of production employed in this research could be
utilized to an economic advantage when compared with the prices of the same type of
pipes in SA market.

A finite element model of the electrofusion welding of thermoplastic pipesRosala, George F., Day, Andrew J., Wood, Alastair S. January 1997 (has links)
An advanced finite element (FE) model of the electrofusion welding of thermoplastic
pipes has been developed using the ABAQUS FE package. The heat transfer analysis is coupled with
thermal deformation analysis to include the time-dependent closure of the initial gap between the
pipe and fitting. The effect of radial melt movement into the interface is modelled using a new `virtual
material movement¿ technique. The predicted results (temperature distribution in the weld region,
melt affected zones and gap closure time) are compared with experimental data and good agreement
is found
