Noryl GFN2 (20% glass fibre) fatigue

thread712-12634

Noryl GFN2 (20% glass fibre) fatigue

Noryl GFN2 (20% glass fibre) fatigue

(OP)
An injection moulded part used in a coffee machine seems to loose strength with time/use and break. New mouldings have more than adequate strength for the job. Has anyone experience with ageing of Noryl in a damp coffee/milk environment. Examination of failed parts(broken edges) shows no obvious sign of fatigue, but its complicated by the fibres in the break. Ideas on what to look for ?

If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
