PROBLEM TO BE SOLVED: To design upholstery hardly folded while suppressing increment in weight in the upholstery.SOLUTION: A ceiling member 10 is designed, the ceiling member 10 being formed of a composite material comprising: a substrate 11 made of urethane foam; a first reinforcement layer 12 which is made of glass fiber and attached on the design surface side of the substrate 11; second reinforcement layer 14 which made of the glass fiber and attached on the backside of the substrate 11. When the folding limit load of the ceiling member 10 is defined as Fc, the thickness of the ceiling member 10 is defined as T, the weight/mof the first reinforcement layer 12 is defined as W1, the 1/2 value of the distance ΔD between support points on which the ceiling member 10 is supported is defined as support pitch, the correction coefficients of T, W1, and ΔD are respectively defined as positive value K1, positive value K2, negative value K3, and the constant term is defined as C1, at least one of the thickness of the ceiling member 10, the weight/mof the first reinforcement layer 12 and the support pitch is designed based on a regression formula established between Fc and, T, W1, ΔD.SELECTED DRAWING: Figure 5

    【課題】内装部材の重量の増加を抑制しつつ、折れにくい内装部材を設計することができる。【解決手段】ウレタンフォームにより形成された基材11と、ガラス繊維により形成され、基材11の意匠面側に貼着された第1補強層12と、ガラス繊維により形成され、基材11の裏面側に貼着された第2補強層14とを含む複合材料によって形成される天井部材10を設計する。天井部材10の折れ限界荷重をFcとし、天井部材10の厚さをTとし、第1補強層12の目付をW1とし、天井部材10が支持される支持点間の距離ΔDの1/2の値を支持ピッチとし、T、W1、及びΔDの補正係数をそれぞれ正の値であるK1、正の値であるK2、及び負の値であるK3とし、定数項をC1とするとき、Fcと、T、W1、及びΔDとの間に成立する回帰式に基づいて、天井部材10の厚さ、第1補強層12の目付、及び支持ピッチの少なくとも1つを設定する。【選択図】図5
