Carbon fiber composite lattice structure filled with silicon rubber

In the present study, the highly efficient composite lattice structures were filled with silicon rubber in their enormous space, to enhance their mechanical property and energy absorption capacity. Out-of-plane compression tests were carried out to evaluate the enhancement. The initial response and failure mode of the newly developed structure kept the same as that before filling. However, a higher stress level region was appeared which benefited to its energy absorption. (C) 2011 Published by Elsevier Ltd. Selection and peer-review under responsibility of ICM11
