Use of compression molding with a natural fiber-reinforced thermoplastic matrix has been growing rapidly within the last few years in various applications. Wood-reinforced high-density polyethylene offers economic efficiency, a high process reproducibility, short cycle times, a stable and high component quality, and a good recycling ability. In the present study, the distribution of fiber orientation using micro-CT scanner for compression-molded product of varying fiber content was measured, and the effects of fiber content with respect to orientation states are discussed.
