- Abstract
The aim of this study was to verify the influence of the compression molding temperature on thermomechanical properties of the basalt-reinforced poly(lactic acid) (PLA) composites. The thermomechanical properties of the composites were determined in the course of dynamic mechanical thermal analysis (DMTA), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), static tensile test and tensile impact strength test. The incorporation of basalt fiber into poly(lactic acid) matrix led to obtaining environmentally friendly composite materials with good mechanical properties. The composite production process carried out at different temperature set-ups (170°C, 180°C, 190°C and 200°C) led to the development of composite materials characterized with favorable mechanical properties and specific structure. The simultaneously realized thermal, thermo-mechanical and mechanical analyses allowed to describe the limitation processes resulting from the application of different compression molding temperatures. The best thermomechanical properties were recorded for the composites pressed at the highest temperature (200°C).
