Title (EN) MOLDED BODY AND PROCESS FOR PRODUCING THE SAME
(FR) OBJET MOULÉ ET PROCÉDÉ DE PRODUCTION DUDIT OBJET MOULÉ
Abstract:
(EN) The invention relates to the use of a fibre-reinforced composite (K) in a thermoforming process. Moreover, a process for thermoforming a fibre-reinforced composite (K) to a molded body (M) is disclosed, the process comprising at least the following steps: (i) Providing a fibre-reinforced composite (K) as described herein; (ii) Heating the fibre-reinforced composite (K) to a temperature (T3) at which the at least one substantially amorphous matrix polymer composition (B) is substantially softened; (iii) Thermoforming the fibre-reinforced composition (K) in a mold at a mold surface temperature (T4) in order to obtain a molded body (M); (iv) Releasing the molded body (M) from the mold; wherein the mold surface temperature (T4) is ≥ 50°C.
(FR) L'invention concerne l'utilisation d'un composite renforcé par des fibres (K) dans un procédé de thermoformage. L'invention concerne en outre un procédé de thermoformage d'un composite renforcé par des fibres (K) sur un corps moulé (M), le procédé comprenant au moins les étapes suivantes : (i) fournir un composite renforcé par des fibres (K) tel que décrit dans la description ; (ii) chauffer le composite renforcé par des fibres (K) à une température (T3) à laquelle ladite composition de polymère à matrice sensiblement amorphe (B) est sensiblement ramollie ; (iii) thermoformer la composition renforcée par des fibres (K) dans un moule à une température de surface de moule (T4) afin d'obtenir un corps moulé (M) ; (iv) libérer le corps moulé (M) du moule ; la température de surface de moule (T4) étant ≥ 50 °C.
