Abstract The purpose of the present invention is to improve the adhesion between layers in a layered body when the layered body is molded by lamination/integration by thermal molding. A two-part reactive composition according to an embodiment is used for forming a thermoplastic matrix resin for a thermoplastic resin composite material containing fibers as a reinforcing material. The two-part reactive composition comprises an active hydrogen component comprising an aromatic diamine having an alkylthio group and an isocyanate component comprising at least one diisocyanate selected from the group consisting of an aliphatic diisocyanate, an alicyclic diisocyanate and modified products thereof. The diisocyanate comprises a blocked diisocyanate in which at least one of isocyanate groups is blocked and a non-blocked diisocyanate in which isocyanate groups are not blocked. Le but de la présente invention est d'améliorer l'adhérence entre des couches dans un corps stratifié lorsque le corps stratifié est moulé par stratification/intégration par moulage thermique. Une composition réactive en deux parties selon un mode de réalisation est utilisée pour former une résine de matrice thermoplastique pour un matériau composite de résine thermoplastique contenant des fibres en tant que matériau de renforcement. La composition réactive en deux parties comprend un composant hydrogène actif comprenant une diamine aromatique ayant un groupe alkylthio et un composant isocyanate comprenant au moins un diisocyanate choisi dans le groupe constitué par un diisocyanate aliphatique, un diisocyanate alicyclique et des produits modifiés associés. Le diisocyanate comprend un diisocyanate bloqué dans lequel au moins l'un des groupes isocyanate est bloqué et un diisocyanate non bloqué dans lequel des groupes isocyanate ne sont pas bloqués. 熱成形により積層一体化して積層体を成形した場合に、当該積層体の層間での接着を向上する。 実施形態に係る二液反応型組成物は、強化材として繊維を含む熱可塑性樹脂複合体の熱可塑性マトリックス樹脂を形成するために用いられる。該二液反応型組成物は、アルキルチオ基を有する芳香族ジアミンを含む活性水素成分と、脂肪族ジイソシアネート、脂環式ジイソシアネートおよびこれらの変性体からなる群から選択された少なくとも一種のジイソシアネートを含むイソシアネート成分と、を有する。該ジイソシアネートは、少なくとも一方のイソシアネート基がブロックされたブロック化ジイソシアネートと、イソシアネート基がブロックされていない非ブロック化ジイソシアネートと、を含む。
