I. Intro

Date: 10/02/2023

This time we were making leading edge and trailing. We added an extra rubber sheet on the top.

II. Procedure

Figure 1: de-mold

Figure 2: trailing edge mold

Figure 3: we were using solid release this time.

Figure 4: back film is removed before warping it.

Figure 5: put peel ply under it.

Figure 6: then another layer of solid release film.

Figure 7: put rubber sheet on the top.

Figure 8: put it in the vacuum bag. The trailing edge should be facing the fold of the vacuum bag.

Figure 9: put it into the vaccum bag.

Figure 10: the student on the other side of the table put it in the wrong direction. The pointy edge should be at the fold, not the vertical edge.

Figure 11: waitingfor vacuum.

Figure 12: this was how much I got for the leading edge.

Figure 13: same percedure as the trailing edge.

Figure 14: the mold I was using didn’t have the hollow part at the bottom, so I don’t need to put the honeycomb at the bottom to hold the vacuum port.

Figure 15: autoclave.

Figure 16: finally the trailing edge was ready to go. It was fine before TA came, but somehow it started leaking.

Figure 17: nose rib I did last time.
