Abstract

L’invention concerne une composition pour matériau composite thermoplastique comprenant : a) de 65 à 95% en poids d’au moins un prépolymère polyamide semi-cristallin réactif de masse molaire moyenne Mn inférieure à 5000 g/mol et présentant un diamètre moyen D50 en volume des particules de poudre de prépolymère polyamide semi-cristallin réactif compris de 10 à 300 µm, b) de 5 à 35% en poids d’au moins un ignifugeant choisi parmi un ignifugeant au moins partiellement fusible sous forme de poudre et présentant un diamètre moyen D50 compris de 10 à 300 µm, et un ignifugeant non fusible sous forme de poudre préalablement broyée et présentant un diamètre moyen D50 compris de 1 à 50 µm, et c) de 0 à 2% en poids d’au moins un additif, et ledit prépolymère polyamide réactif comprenant ou étant constitués d’au moins un copolyamide Z/BACT/XT dans lequel : - BACT est une unité à motif amide présente à un taux molaire allant de 10 à 65%, - XT est une unité à motif amide présente à un taux molaire allant de 30 à 60%, - Z est une unité à motifs amide présente à un taux molaire allant de 5 à 30%, la somme molaire Z + BACT + XT étant égale à 100%, et la somme des constituants a) + b) + c) étant égale à 100%, ledit prépolymère polyamide semi-cristallin réactif présentant une température de fusion Tf < 300°C, une température de transition vitreuse Tg > 80°C, et un écart entre la température de fusion et la température de cristallisation Tf -Tc < 70°C.
