assignment
   group assignment:
      produce test coupons for your composite fabrication process(es)
   individual assignment:
      read the safety data sheet (SDS) and technical data sheet (TDS)
         for the resins that you're using
      design and fabricate a 3D mold (~ft2)
         and produce a fiber composite part in it,
         with resin infusion and compaction
