What is the preparation method of polymer-based composites?

1, resin and various additives (mainly thermosetting, and the estimation of thermoplasticity is similar)

① Thermosetting resins mainly include phenolic (thermosetting), unsaturated polyester, polyurethane, epoxy, polyimide, polysulfone, etc.

② Thermoplastic resins mainly include polypropylene, polyethylene, polyvinyl chloride, phenolic (thermoplastic) and so on.

③ Auxiliary agents include: pigments, accelerators, curing agents (initiators), cross-linking agents/diluents (one substance can play two roles, like styrene in resin), polymerization inhibitors, photosensitizers, release agents, low shrinkage agents, etc.

2. Reinforcing materials

Glass fiber, glass fiber cloth, glass fiber felt, carbon fiber and its products, metal fiber, etc.

Step 3 pack

The function of filler is mainly to improve the performance of products (such as rigidity, shrinkage, corrosion resistance, toughness, electromagnetic heat, etc.). ) and reduce the processing cost. Whether filler needs to be added depends on product requirements and process conditions.

4. Processing technology (the processing methods you mentioned have their own advantages and disadvantages, and the properties of the products obtained are different. Choose different technologies according to the required performance, output and complexity)

Hand paste, pultrusion, molding, winding, spraying, injection, etc.
