| Research Abstract |
In the present study, hybrid functionally-graded polymeric material that is syntactic foam having graded density distribution was developed for enhancing impact-energy absorption. Fabrication processes were proposed to produce functionally-graded foams by floating phenomenon of micro-balloons in matrix resin. Dynamic viscoelastic measurements and compression test revealed that the local mechanical properties of the fabricated foams were determined by the properties of the matrix resin and the volume fraction of the micro-balloons. Moreover, one-dimensional stress wave analysis demonstrated that the foams have high-energy absorption capability and can reduce the transmitted force in impact loading.
