摘要：

The energy release rate at steady-state fracture of glass fiber mat-reinforced polypropylene (GMT-PP) composites of different degree of consolidation was determined by various methods considering the mechanical energy (G(ss)), acoustic emission energy (G(AE)) and heat (G(h)) release rates. All these energy release rates showed the same tendency, namely increase with increasing surface weight (consolidation degree) of the GMT-PP sheets. To determine the initiation fracture toughness (K-lC) the resistance curve concept was adopted. K-lC increased whereas the related strain energy release rate (G(IC)) did not change with the consolidation degree. (C) 2003 Published by Elsevier Science Ltd.
