Title:
METHOD FOR PRODUCING THERMOSETTING PHENOLIC RESIN-BASED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/070727
Kind Code:
A1
Abstract:
Provided is a method for producing a thermosetting phenolic resin-based composite material. A vacuum infusion process is used, a thermosetting phenolic resin is used as a resin matrix, the thermosetting phenolic resin contains not more than 25% by weight of an organic solvent, and the viscosity under the infusion temperature is less than 300 mPa.s; when the resin is cured, an acidic curing agent is not added, gradient temperature heating curing is adopted, the infusion temperature is 50-70℃, and the highest-stage curing temperature is 100-130℃. The production process is simple, the investment is low, the cost is low, the application range is wide, and the prepared composite material is low in porosity and excellent in performance.
