黒染絹布を用いた漆調ガラス繊維強化プラスチックの創生

抄録

The objective of the present work is to fabricate Urushi-like glass fiber reinforced plastic (GFRP) by using black silk fabric. We first manufactured a GFRP molded plate consisting of various laminate layers, and compared the surface color with that of Urushi products. Subsequently, we used impression evaluation to reveal how the GFRP plate fabricated using the black silk fabric was rated. The study results confirmed that L* and a* values of the GFRP sample were similar to those of the Urushi sample. In the impression evaluation, almost half of the subjects considered the GFRP sample fabricated using the black silk fabric (with lightness similar to that of the Urushi product) as the original Urushi product. The subjects also associated more “beauty,” “sense of luxury and high quality,” and “depth of blackness” with the sample regarded as the Urushi product than with the sample not regarded as the Urushi product.
