Abstract
【解決手段】ガラスマット間にバガスシートを挿入して強度の向上と機能の発揮を行う。繊維状バガスを用いて不飽和ポリエステルと混合した後、加熱プレス機を用いて金型に装填後加圧加熱してバガスシートを作製する。その際シートはバガスの繊維長さと含有量を変化させる。加圧力10MPa、加熱温度150℃で5分保持後冷却した成形体の密度の比較よりバガスシートを含む成形体は軽い。これはバガス繊維内部が多くの空洞部から構成されるハニカム構造に起因している。さらに成形体の比曲げ強度を比較すると、バガスシート(BS)有りの場合は無に比較して約30%の強度の向上が見出され、バガスシートが亀裂の進展抑制に効果的に作用する。
