1. Research Progress in Rosin-Modified Phenolic Resins

Rosin-modified phenolic resin composites exhibit exceptional combined properties. Studies indicate that incorporating an optimal amount of rosin resin significantly improves the heat resistance, compressive strength, and wear resistance of phenolic resins. Additionally, rosin resin enhances processability by reducing melting temperatures and minimizing shrinkage rates. These advantages position rosin-modified phenolic resins as promising materials for aerospace, automotive manufacturing, and electronics industries.

2. Preparation Methods for Rosin-Modified Phenolic Resins

Current methods for fabricating rosin-modified phenolic resins include:

(1) Blending Method: Mixing rosin and phenolic resins in specific ratios followed by shaping. While cost-effective and straightforward, this approach may compromise mechanical strength and thermal properties.

(2) Filling Method: Introducing fillers (e.g., glass fibers, carbon fibers) into phenolic resins. Fillers improve mechanical and thermal performance but can reduce processability and electrical properties.

(3) Cross-Linking Method: Chemical cross-linking of phenolic resins using agents to enhance thermal and mechanical properties. This method yields superior performance but requires precise control to avoid excessive by-products.

Owing to their versatile properties, these composites find applications in:

• Construction: Fireproof doors/windows and structural materials.
• Electronics: Protective layers and insulation for circuit boards.
• Aerospace: Bearings, gears, and other critical components in aircraft engines.
