Assignments

-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 and produce a fiber composite part in it, with resin infusion and compaction

Hardware and Softwares used

-Fusion 360
-Mesh Lab

-Shopbot

Outcome

Do 3D cnc cutting, made a fabric composites.

Composites

Test burlap composites

As a group assignment, we tested burlap composites. We tested 1 to 5 multi layers of burlap.




We used a local epoxy. Click here to get a datasheet.

-The mix ratio is Adehsive2: Hardener 1.
-The product is a transparent type and multi-use epoxy adhesive.
-Room temperature curing type.
-Automatic mixer (2 minutes) If you use chopsticks (3 minutes ~ 4 minutes)
-It is about 6 ~ 8 hours for first tack curing time (do not touch by hand) and 24 hours for full curing.
-In case of thermal curing, curing at a temperature of 50 to 60 ° C for about 1 hour.

-wear 3 layers of latex gloves.
-keep the trash bin close.
-wear the gloves and mask.








Fusion 360, Mesh Lab


Aspire


- endmill setting for rough cut.


-endmill setting for finish cut.

Shopbot


-I sand the seashell with sand paper. it looks nice.


-Becuase I choose convetional, chips does not look flying away.


Epoxy


I had to put the blue lid aside of seashell.
