Experimental determination of dispersion relationship of polyamide thin beams

Abstract

Due to its superior mechanical properties, polyamide represents the most frequently used polymer material for additive manufacturing of automotive and aerospace components. With the perspectives of future use for on-site production in space, the field of application is extending to larger structures, raising interest for dynamic behavior of polyamide structures. The paper presents experimental study of dynamic response of thin beams made of three different types of polyamide: polyamide PA6, composite polyamide PA6 with 30% of glass fibers and polyamide PA12 obtained by selective laser sintering of polyamide powder PA2200. The results show that the dynamic response of polyamide beams is similar to metal beams.
