Experiment Preparation of raw materials.
Preparation of raw materials→ fibers drying→ mixing→ adding TAIC → molding→ cold forming→ samples of composites.
Conclusions Using the waste cotton stalk basts which were degummed as reinforced materials, PLA as the matrix and TAIC as a cross-linking agent, a new kind of composite with good heat-resistance and low cost can be produced.
