The thickness and density of the pad back metal and friction member) were measured, and the degree of variation was compared. The results are shown in Table 2. The measurement conditions are as follows.
（１）成形品の厚み寸法
各々の成形条件で得られた２０個の成形品について、その外周部４箇所（四隅）のエッジから１０±３ｍｍのポイントを、マイクロメータで厚み寸法ｔ１（裏金＋摩擦部材）を測定した。４箇所の厚み寸法の最大値と最小値の差をｔ２として、厚み寸法のばらつきを比較した。その結果を表３に示す。なお、表３において、成形品の厚み寸法の差ｔ２は数字が小さいほどばらつきが少ないことを示す。
(1) Thickness dimension of molded article About 20 molded articles obtained under each molding condition, a point of 10 ± 3 mm from the edge of the four outer peripheral portions (four corners) was measured with a micrometer in thickness dimension t 1 (back metal + Friction member) was measured. The difference between the maximum value and the minimum value of the thickness dimension of the four places as t 2, and compared variations in thickness. The results are shown in Table 3. In Table 3, the difference between t 2 of the thickness of the molded product indicates less variation smaller number.
（２）成形品の密度
上記（１）で測定した４箇所の厚み寸法の平均値からプレートの厚み６ｍｍを差し引いて摩擦部材の平均厚みを算出し、成形品の面積５０ｃｍ２との積より摩擦部材の体積を求めた。

(2) Density of molded product The average thickness of the friction member is calculated by subtracting the plate thickness of 6 mm from the average value of the four thicknesses measured in (1) above, and the friction is obtained from the product of the molded product with an area of 50 cm 2. The volume of the member was determined.
Moreover, the density (g / cm < 3 >) was computed as the material loading of a friction member 100g.
Further, for each molding condition, a standard deviation σ was calculated from the measurement results of 20 molded products, and density variations were compared. The results are shown in Table 4. In Table 4, the standard deviation σ of density indicates that the smaller the number, the less variation. The standard deviation σ was obtained by the following equation using 20 specimen data of the molded product density (k: 1 to 20).
