Injection moulded micro parts and microstructured surfaces require accurate replication of micro-scale features, which depends on polymer properties, features geometry and process parameters. The objective of this paper is to improve the replication quality of moulded micro-scale features by blending a PA66 with a LCP additive. Both experimental tests and numerical modelling were used to evaluate the single and combined effects of the polymer rheological properties, moulding conditions and features orientation on the replication at different contents of LCP. Tensile tests were also carried out to assess how LCP affects the PA66 mechanical properties.

Abstract

Injection moulded micro parts and microstructured surfaces require accurate replication of micro-scale features, which depends on polymer properties, features geometry and process parameters. The objective of this paper is to improve the replication quality of moulded micro-scale features by blending a PA66 with a LCP additive. Both experimental tests and numerical modelling were used to evaluate the single and combined effects of the polymer rheological properties, moulding conditions and features orientation on the replication at different contents of LCP. Tensile tests were also carried out to assess how LCP affects the PA66 mechanical properties.
