ABSTRACT = {The residual resources of ramie fiber-based textile products were used as raw materials. Ramie fiber felt (RF) was
modified by NaClO<sub>2</sub> aqueous solution and then impregnated with water-based epoxy resin (WER). RF/WER
transparent composite materials were prepared by lamination hot pressing process. The composite materials’color
difference, transmittance, haze, density, water absorption, and mechanical properties were determined to assess
the effects of NaClO<sub>2</sub> treatment and the number of ramie fiber layers on the properties of the prepared composites. The results showed significantly improved optical and mechanical properties of the RF/WER transparent
composites after NaClO<sub>2</sub> treatment. With the increase of ramie fiber layers, the composites’ whiteness, transmittance, and water absorption decreased while the haze increased. For material with three layers, the optical transmittance in the visible light region was 82%, and the haze was 96%, indicating the material has both high
transmittance and high haze characteristics. The tensile strength increases with the increase of the number of
layers, and the tensile strength of the composite with six layers is 243 MPa. This study broadens the scope of
application of ramie fiber as a new option for home decoration materials.},
