ENGLISH OVERVIEW

Resin formulation and composite processing

Epoxy, reinforcement, forming and inspection

Start with epoxy and its cure system, distinguish fibers, fillers and rheology additives, then follow manufacturing routes to material outputs.

Reading paths

Epoxy formulation: cure, fillers and rheology

Amines and anhydrides serve multiple processes; fumed silica modifies rheology rather than curing the resin.

Reinforcement, cores, preforms and consumables

Fibers, structural cores and process consumables have different roles. Separate dry preforms from resin-containing prepregs.

Prepreg: autoclave, oven and press routes

Check the prepreg grade first. AFP/ATL are placement technologies and vacuum bags provide consolidation, not another hardener.

Liquid molding: infusion and RTM

Both introduce resin into dry reinforcement, but tooling, injection pressure and filling control differ.

Continuous reinforcement: pultrusion and winding

Pultrusion makes continuous profiles; winding makes suitable shells. Cure-system selection still depends on equipment and process windows.

Casting and potting: amines, anhydrides and fillers

Casting is not restricted to amines; filled electrical castings differ from fiber-laminate structures.

Spray coatings versus chopped-fiber spray-up

One controls coating atomization and rheology; the other co-deposits resin and reinforcing fibers. They are different processes.

Material outputs and qualification

Cure, internal defects, dimensions and properties require coordinated verification; each product retains its own qualification requirements.

Inputs, process and technical priorities

Formulations and processes have many-to-many relationships. Fiber composites, filled castings and coatings are connected but distinct products.

Start with three formulation examples

These are explanatory routes, not exclusive formulations or ready-to-use mixing recipes.

  • Epoxy plus compatible amine hardener → casting/potting; anhydride casting products also exist.
  • Epoxy plus anhydride/accelerator and continuous fiber → pultrusion; fast amine routes also exist.
  • Epoxy plus amine and optional fumed silica → rheology control, with spray compatibility requiring verification.
