Development of high-strength green composites based on ramie sliver and cellulose acetate resin

In the present study, the tensile properties of a single ramie fiber and the adhesion of ramie and a resin were compared at 170, 180, 190, 200, 210 and 220 degrees C. The results revealed that the most suitable temperature for the formation of a unidirectional composite is 190 degrees C. The tensile properties of the non-woven ramie fiber fabric, woven ramie fiber fabric, ramie fiber yarns, or sliver reinforced composites were tested and compared, and their structures were analyzed by X-ray computed tomography. The results revealed that sliver was the most suitable reinforcing material for unidirectional composites. We also know that the tensile strength and tensile modulus increased as the fiber volume content increased, and the relationships between them were linear.

Automated summary

This study compared the tensile properties of ramie fibers and the adhesion of ramie and resin at different temperatures. The results showed that 190 degrees C was the most suitable temperature for the formation of unidirectional composites. The study also found that sliver was the most suitable reinforcing material for unidirectional composites, and the tensile strength and modulus increased linearly with the fiber volume content.
