MDF AND PLYWOOD ANALYSIS

HOW TO IMPROVE BENDING PROPERTY OF MDF AND PLYWOOD? PATTERN SAMPLES ON MDF 04

Figure 28: 5mm hexagon edge

Figure30: HEXAGONAL

In Figure 26, 7 different pattern samples are produced. Most of them performed in 1 way of bending. Figure 26B was able to bend in 2 directions, however, due to the rectangular geometry, its bending capacity was limited.

In Figures 27-29 hexagonal pattern is tested. The hexagonal pattern allowed the bending in 2 directions and peformed better than the pattern 26B. So, different pattern scales are also tested in MDF. When the pattern scale gets smaller, as in the Figure29, the MDF started to be broken.

However, MDF material tends to brake in most of the bending trials, so the same pattern tried on Plywood as well as in Figure 30. Figure 31: SQUARE SPIRAL ON 1.5mm PLYWOOD

Figure32: FINAL PATTERN/ PLYWOOD ON 1.5mm PLYWOOD

After the trial of the hexagonal pattern in plywood, in Figure 31 a different pattern is applied. The square spiral pattern was the best option that has been explored. In the Figure32, the plywood surfaces are popping out when the bending is occurred. As the spiral pattern allows the extraction of the surfaces during bending, the pattern was the optimal choice for our geometry. After this pattern trial on a rectangular surface, it is also applied to our unrolled geometry.
