Abstract
Description

下記表中に示す条件に従い、タイヤ内で使用される状態のスチールコードと未加硫ゴムとの複合体シートを作製して、その曲げ剛性および部材重量を測定し、比較した。すなわち、生タイヤの変形は、タイヤの骨格材であるカーカスプライの曲げ剛性が小さい場合に顕著に現れるものであるので、複合体シートの曲げ剛性を、変形に対する抵抗力の指標として用いた。
複合体シートの曲げ剛性は、100mmの間隔で複合体シートを支持し、その中間点を、3点曲げの要領で15mm押し込んだ際の押し込み量と押し込み力とのカーブを測定することにより評価した。押し込み過程における押し込み力をP(N)、押し込み量をδ(mm)とすると、その傾きΔ=dP/dδ(N/mm)が得られ、保持間隔をL(mm)としたとき、G=(E×9.8)×I=Δ×L3/48(N・mm2)(E:縦弾性係数(kgf/mm2)、I:断面2次モーメント(mm4))で測定される。値は、δ=10mm、L=100mmの条件下で比較した。
