✦ Synopsis

The thermal stability and the mechanical properties of modified and unmodified glass-reinforced polypropylene during aging in air (135Β°C) and antifreeze (115Β°C) with exposure up to 80 days was investigated in this study. Aging leads to progressive phase separation. On the contrary, the original modified composite is characterized by a dense structure; aging leads to the structure compacting and pore size decreases. Unmodified composite displays a drastic failure of the mechanical properties after 10 days of heating.

The damage mechanisms in two structurally different glass mat reinforced polypropylene materials were studied. In situ microscopy was applied during the tensile testing of thin notched sheets. Micrographs of the damage processes in the two materials are presented. The major points of damage initiati
