Week no. 14

Composites :

  • read the material safety data sheet (MSDS) 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

Design a 3D Mold

This week i thought i might would make and alternative for my previous cover for my brake ligh, but this time
with resin and fiberglass:

Started by designing the mold, for that i used Rhino:


Fabricate the 3D Mold

Then I exported the Rhino model to an stl file and imported the stl to Autodesk 123D Make:

After this i exported a pdf file with de model plans and
cutted it on the laser cuter machine and did the assemble:

 


Produce the Fiber Composite Part

Materials Used:
  • I used the CLR Epoxy Resin with the CLF Hardener, Resin and Hardner in 100:47 ratio.(Guide);
  • Peel ply and release film;
  • 2 fiberglass layers;
  • Plywood mold;
  • Scale;
  • Vaccum bag.


First I started with a layer of release film and peel ply, next 2 layer of fiberglass and resin and another
ayer of release film and peel ply. After all the layers are piled, I used the vaccum bag with the vacuum pump:

I took the vaccum off after 24 hours, and this was the final result:
