AI Technical Summary
Technical Problem
Existing resin composite materials with natural fibers struggle to maintain the visibility of natural fibers, especially when using transparent biodegradable plastics, as light passing through the resin obscures the fiber visibility.
Method used
A resin composite material with a transparent resin portion and a coating layer on the natural fibers, where the refractive index of the coating layer is different from that of the resin portion, allowing light to be directed to the natural fibers without passing through the resin, thereby enhancing their visibility.
Benefits of technology
The solution significantly improves the visibility of natural fibers, contributing to better design aesthetics and functionality of the resin composite materials.

Abstract
To further improve visibility of a natural fiber, from the viewpoint of securing designability of a resin composite material.SOLUTION: In a resin composite material 2 having a fiber part 3 containing a natural fiber 30, and a transparent resin part 4 including the fiber part 3, a coating layer 5 formed of a polymer material is provided on the surface of the natural fiber 30, the natural fiber 30 is visually confirmable from outside through the resin part 4 and the coating layer 5, and there is a difference in refractive indices between the coating layer 5 and the resin part 4.SELECTED DRAWING: Figure 4
