In order to study the long-term creep behavior of glass fiber (GF) reinforced polypropylene
(PP) composites and neat PP three point (3P) bending and short-term creep measurements
out, and the results were analyzed. The constant force rate 3P bending, and short-term
lasting for 30 minutes were performed on injection molded glass fiber reinforced PP
composites having 6
different fiber contents. The constant force rate was used until the specimen failed
or the preset load
level was reached.
