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.
