Product creep performance substandard

The creep performance of LGFPP depends on effective load transfer of the fiber skeleton

Molding Process creepconstant loadstress relaxationhigh molecular weight PPfiber orientation

Long glass fiber poor impregnation causing dispersion difficulty

Full impregnation of fibers is the prerequisite for exerting the reinforcement effect
