Epoxy Resin Prepreg Preparation Apparatus and Method

Introduction:

The process of preparing epoxy resin prepreg involves a sophisticated device designed to facilitate efficient and precise manufacturing. This apparatus comprises various components, including winding roller shafts, transmission mechanisms, and additional features to enhance the prepreg manufacturing process.

Apparatus Components:

1. Winding Roller Shafts:

   • Single-Sided Release Paper Winding Roller Shaft
   • Double-Sided Release Paper Winding Roller Shaft
   • Product Winding Roller Shaft
   • Single-Sided Release Paper Winding Feed Roller Shaft
   • Fiber Woven Fabric Winding Roller Shaft

2. Transmission Mechanisms:

   • First, Second, and Third Chain Transmission Mechanisms
   • First and Second Gear Transmission Mechanisms
   • Fourth Chain Transmission Mechanism

3. Additional Features:

   • Intermediate Roller Shaft
   • Frame
   • Spring
   • Adjusting Screw

Operational Connectivity:

The apparatus components are intricately connected to ensure a seamless manufacturing process:

• The first shaft is linked to the second shaft through the first chain transmission mechanism.
• The second shaft connects to the double-sided release paper winding roller shaft via the second chain transmission mechanism.
• The double-sided release paper winding roller shaft is connected to the single-sided release paper winding roller shaft through the first gear transmission mechanism.

Fiber Woven Fabric Component:

A fiber woven fabric winding roller shaft, equipped with a spring and adjusting screw, is introduced to enhance the prepreg formation. This component is positioned between the single-sided and double-sided release paper winding roller shafts.

Temperature Control and Matrix Resin Overflow Prevention:

• Both the single-sided and double-sided release paper winding roller shafts incorporate closed cavities filled with a circulating heating medium.
• These closed cavities are interconnected through pipelines.
• Baffles, positioned at the ends of the release paper winding roller shafts, prevent matrix resin overflow during the manufacturing process.

Specialized Components:

• The apparatus includes a magnetic particle clutch on various roller shafts, such as the product winding roller shaft, single-sided release paper winding roller shaft, fiber woven fabric winding roller shaft, and their corresponding feeding roller shafts.

Material Specifications:

• The epoxy resin utilized includes E-51 epoxy resin, B-44 epoxy resin, or E-20 epoxy resin.
• Phenolic epoxy resin options consist of F-44, F-48, or F-51 phenolic epoxy resin.
• The core-shell polymer is composed of polybutadiene rubber, styrene butadiene rubber, or polymethyl siloxane as a soft core, and polymethyl methacrylate as a hard shell.

Conclusion:

The described apparatus and method provide a comprehensive and controlled environment for preparing epoxy resin prepreg, ensuring quality and precision in the manufacturing process.
