PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer, capable of easily conducting lamination molding with a carbon fiber reinforced plastic (CFRP), high in adhesiveness with CFRP, capable of improving impact resistance of the carbon fiber reinforced plastic by integral molding with CFRP, and further good in adhesiveness even in molding after long term storage and capable of lamination molding with CFRP.SOLUTION: There is provided a thermoplastic elastomer for carbon fiber reinforced plastic adhesion lamination, which is contained in an adhesive layer laminated on a layer consisting of a carbon fiber reinforced plastic, contains a styrenic thermoplastic elastomer and an α,β-unsaturated carboxylic acid modified polymer, in which the styrenic thermoplastic elastomer contains at least Component (c): hydrogenated styrene-isoprene block copolymer, and concentration of α,β-unsaturated carboxylic acid derived from the α,β-unsaturated carboxylic acid modified polymer is 0.01 to 10 mass%.SELECTED DRAWING: None

    【課題】炭素繊維強化プラスチック(CFRP)との積層成形を容易に行え、CFRPとの密着性が高く、CFRPとの一体成形で炭素繊維強化プラスチックの耐衝撃性を改良することができ、しかも、長期保管後の成形においても密着性がよくCFRPと積層成形することが可能な熱可塑性エラストマーを提供する。【解決手段】炭素繊維強化プラスチックよりなる層に積層される接着層に含まれる熱可塑性エラストマーであって、スチレン系熱可塑性エラストマーとα,β−不飽和カルボン酸変性ポリマーとを含み、該スチレン系熱可塑性エラストマーが少なくとも成分(c):水添スチレン−イソプレンブロック共重合体を含み、該α,β−不飽和カルボン酸変性ポリマー由来のα,β−不飽和カルボン酸濃度が0.01〜10質量%である炭素繊維強化プラスチック接着積層用熱可塑性エラストマー。【選択図】なし
