碩士 === 國立交通大學 === 機械工程系所 === 106 === Fabricating framework materials have drawn much attention recently because of its application in ultralight materials. Open-cell cellular solid structures can be simplified into framework structures when their relative density are lower than 0.2. In addition, the improvement of additive processing techniques make possible to generate ideal samples for studies. In the present study, we propose a different way to fabricate framework structure. Instead of additive processing, we used a subtracting process. The sample are made of polydimethylsiloxane (PDMS) and we used the rheometer to measure Young’s moduli. We found that there are non-negligible bubbles trapped inside PDMS so the density must be corrected. We found the relationship between the relative Young’s modulus and relative density can be expressed as 。
