ABSTRACT:
A process for the manufacture of glass fiber-reinforced polyester products is disclosed. A ready-to-mold resin and reinforcement composite is prepared using an initiator which has been microencapsulated in order to prevent initiator-induced cross-linking of the resin reactants. The initiator is released during the molding of the composite by rupture of the microcapsules due to internal vapor pressure developed at a preselected molding temperature. The encapsulation of the initiator provides improved homogeneity and increased flowability of the composites during molding, and enables the provision of molded polyester products having higher degrees of cure and more defect-free finish surfaces.
