Thermoplastics reinforced with continuous fibers are very promising building materials
for the auto industry and consumer electronics to reduce the weight of vehicles and portable
devices, and to deliver a high impact tolerance at the same time. Polypropylene is an abundant
thermoplastic, and its glass fibers composites make a valuable solution that is suitable
for mass production. But the adoption of such composites requires a deep understanding
of their mechanical behavior under the relevant loading conditions.
In this Ph.D. work, we aim to understand the damage process in continuous glass fiberreinforced
polypropylene in detail. We will focus in particular on developing an approach
for microscale observation of damage during the out-of-plane loading process and will use
these observations for both qualitative and quantitative evaluation of the composite. We
will apply our approach to two kinds of polypropylene composites, one of them is specially
designed to withstand impact. The comparison between the two types of composites at slow
and fast loading cases will shed some light on the effect of the polymer properties on the
behavior of composites under out-of-plane loading.
