Design ConstraintsPurpose: replace Larry Genalo’s Materials
Engineering demonstration kit
Want to hold and transport around 50 lbs of materials
Integrate into demo by standing on completed container
Design Edges & corners will see
the largest stress concentrationDouble layer of plies at
these points
Risk of sides buckling while standing on top for demoUsed foam core to increase
bending stiffness

Apply First layer
Blueboard foam core
*Inserts not shown
Second layer
Completed with inserts
Complete with wheels and lid attached
Problems Encountered Thin layer of plaster is infused with interior surface.
Complete removal will damage inner wallUse release agent or release film
Difficult to create smooth fiber layer around complex geometryCut plies to exact shapeUse different manufacturing method
Ran out of epoxy - top edge of container was unfinished
