This study investigates aqueous phenolic matrix composites, focusing on their physical, mechanical properties, and morphology. Aqueous phenolic resins are the most widely available type on the market, primarily used in the wood industry, while solvent-based phenolics are mainly used in specific markets like aerospace. Despite extensive research on solvent-based phenolic matrices, aqueous phenolic resins remain relatively underexplored. This research evaluates four curing cycles using Dover Chemical Factory’s LMPF-505™ resin and Jushi’s ESC558™ e-glass fibers. Samples (PFG-1 to PFG-5) underwent hot compression molding with varied curing cycles (CC1 to CC4) and resin pre-conditioning to optimize water content. Analysis reveals that resin viscosity significantly influences distribution; higher water content leads to uneven distribution, while pre-conditioned resin shows improved uniformity. Despite employing four curing cycles, all samples exhibited macro voids, indicating suboptimal consolidation due to insufficient molding pressure and the absence of degassing.

摘要

This study investigates aqueous phenolic matrix composites, focusing on their physical, mechanical properties, and morphology. Aqueous phenolic resins are the most widely available type on the market, primarily used in the wood industry, while solvent-based phenolics are mainly used in specific markets like aerospace. Despite extensive research on solvent-based phenolic matrices, aqueous phenolic resins remain relatively underexplored. This research evaluates four curing cycles using Dover Chemical Factory’s LMPF-505™ resin and Jushi’s ESC558™ e-glass fibers. Samples (PFG-1 to PFG-5) underwent hot compression molding with varied curing cycles (CC1 to CC4) and resin pre-conditioning to optimize water content. Analysis reveals that resin viscosity significantly influences distribution; higher water content leads to uneven distribution, while pre-conditioned resin shows improved uniformity. Despite employing four curing cycles, all samples exhibited macro voids, indicating suboptimal consolidation due to insufficient molding pressure and the absence of degassing.
