    <b>assignment</b>
       <i>group assignment:</i>
          produce test coupons for your composite fabrication process(es)
       <i>individual assignment:</i>
          read the safety data sheet (SDS) and technical data sheet (TDS)
             for the resins that you're using
          design and fabricate a 3D mold (~ft<sup>2</sup>)
             and produce a fiber composite part in it,
             with resin infusion and compaction
