Title
(EN) PRESS MOULDING METHOD
(FR) PROCÉDÉ DE MOULAGE PAR COMPRESSION
Abstract
(EN) A method of press moulding a moulding material to form a moulded part of fibre-reinforced resin matrix composite material, the method comprising the steps of: i. providing a mould tool having a lower mould part (58) and an upper mould part (60), the upper mould part (60) having a first moulding surface (62) for moulding a first moulded surface of the moulded part and the lower mould part (58) having a second moulding surface (64) for moulding a second moulded surface of the moulded part; ii. providing a multilaminar panel of moulding material (66) comprising at least one layer of fibres and at least one layer of resin, the multilaminar panel having first and second opposite major surfaces (68, 70), a surface resin layer of the multilaminar panel being at or adjacent to the first major surface; iii. locating the moulding material in the mould tool; iv. closing the mould tool to define a substantially closed mould cavity containing the moulding material, the closing step including the sub-steps of: a. partially closing the mould tool to define a closed intermediate cavity containing the moulding material (66) the closed intermediate cavity being larger than the moulded part and the first moulding surface (62) of the upper mould part (60) being spaced from the first major surface, the upper mould part (60) being at an elevated temperature as compared to the temperature of the moulding material (66); and b. at least partially evacuating air from the closed intermediate cavity while the first moulding surface (62) of the upper mould part (66) is spaced from the first major surface; v. applying pressure to the moulding material (66) in the mould cavity to configure the moulding material (66) in a fully moulded shape; and vi. substantially fully curing the resin to form a moulded part from the moulding material (66).
(FR) L'invention porte sur un procédé de moulage par compression d'une matière à mouler pour former une pièce moulée en une matière composite de matrice de résine renforcée de fibre, le procédé comprenant les étapes consistant à : i. utiliser un outil de moule ayant une partie de moule inférieure (58) et une partie de moule supérieure (60), la partie de moule supérieure (60) ayant une première surface de moulage (62), destinée à mouler une première surface moulée de la pièce moulée, et la partie de moule inférieure (58) ayant une seconde surface de moulage (64) destinée à mouler une seconde surface moulée de la pièce moulée ; ii. à utiliser un panneau multicouche de matière à mouler (66) comprenant au moins une couche de fibres et au moins une couche de résine, le panneau multicouche ayant des première et seconde grandes surfaces opposées (68, 70), une couche de résine de surface du panneau multicouche étant au niveau de la première grande surface ou adjacente à celle-ci ; iii. à placer la matière à mouler dans l'outil de moule ; iv. à fermer l'outil de moule pour définir une empreinte de moule sensiblement fermée qui contient la matière à mouler, l'étape de fermeture comprenant les sous-étapes consistant à : a. fermer partiellement l'outil de moule pour définir une empreinte intermédiaire fermée qui contient la matière à mouler (66), l'empreinte intermédiaire fermée étant plus grande que la pièce moulée et la première surface de moulage (62) de la partie de moule supérieure (60) étant espacée de la première grande surface, la partie de moule supérieure (60) étant à une température élevée comparativement à la température de la matière à mouler (66) ; et b. évacuer au moins partiellement l'air de l'empreinte intermédiaire fermée pendant que la première surface de moulage (62) de la partie de moule supérieure (66) est espacée de la première grande surface ; v. à appliquer une pression sur la matière à mouler (66) dans l'empreinte de moule pour conformer la matière à mouler (66) à la forme entièrement moulée ; et vi. à durcir sensiblement totalement la résine pour former une pièce moulée à partir de la matière à mouler (66).
