Influence of processing parameters on properties of polyamide filled with glass balls

Abstract

Comparative analysis of thermomechanical properties of polyamide and polyamide composites with addition of 30% of glass balls was performed. The specimens were obtained using the injection moulding technology by means of KraussMaffei KM65-160C1 injection moulding machine. The non-filled polyamide and part of components were injected using the parameters recommended by the manufacturer. A reduced value of mould cooling temperature was used for the other non-filled specimens. The differential scanning calorimetry (DSC), hardness testing, impact strength testing, bending resistance and dynamic mechanical thermal analysis (DMTA) were also performed.
