experimental results measuring torsional strength of CTJM soft structure models.
5.2. Conclusion:
After completing the experimental process and analyzing the results, the team found that
mixing the composite plastic material ratio significantly affects the moment-bearing capacity
and stability of the CTJM model using the distributed model. compliance. In cases with a
higher percentage of PLA plastic, the moment-bearing capacity is greater, conversely, in cases
with a higher percentage of TPU plastic, the force-bearing capacity is reduced and the ability
torsion resistance, increased flexibility. The results achieved can be widely applied in the
fields of robotics, industrial automation, medicine and many other fields.
5.3. Development:
Some development directions to help the project become more complete:

− Further research on the impact on torsional strength when changing or mixing different
types of materials.

− Further research on the influence of changing injection molding parameters.
