The major goal of this work is to study the effects of process parameters (temperature, feed rate and binder force) on the forming of a dome structure comprised of a sandwich structure with alternating layers of aluminum and glass reinforced polypropylene
To ensure product performance, injection molded glass reinforced polypropylene fans were endurance tested at elevated temperatures during the development stage.
Glass reinforced polypropylene is a material that experiences a significant decline in strength at the knitline, Table 1.
Fan blades are available in either pressure cast aluminum or glass reinforced polypropylene
. Features include an airfoil aluminum adjustable pitch impeller, AMCA 'B' construction, a fully reversible airflow option and capacities to 100,000 cfm from stock components.
In addition to the original glass reinforced polypropylene
adjustable nozzle assemblies and quick release couplings, over the past year the company has introduced a range of BSP threaded fixed nozzle holders together with a series of nozzles manufactured from PVDF.
of Exxon Taffen, a 40% glass reinforced polypropylene
selected for its favorable performance relative to hot and cold fatigue, cycle time, strength, and impact testing.
