Fabrication Methods for Thermosets
Thermosets have very low viscosities, and part fabrication involves chemical reactions resulting in solid parts that cannot be melted or reshaped other than by machining processes; they are also difficult to recycle. This chapter addresses part fabrication technologies for thermosetting resins and elastomers. It addresses fabrication of resin parts, advanced composites, rubber parts, and reinforced rubber parts. During part forming, resins undergo exothermic chemical reactions resulting in continually growing crosslinked polymer networks; this phase is called curing. The gel point marks the conversion of low‐viscosity reactants into a highly viscous liquid or solid. Thermoset part fabrication has several distinct forms. The oldest involves compression molding of filled powdered material. The chapter also discusses thermoset fabrication methods such as compression and transfer molding, injection and reaction injection molding, and open mold forming.
