摘要:
Provided is a heat-resistant resin composite excellent in heat resistance and bending properties. This heat-resistant resin composite is constituted of a matrix resin and reinforcing fibers dispersed in the matrix resin. The matrix resin is constituted of a heat-resistant thermoplastic polymer having a glass transition temperature of 100°C or higher, and a polyester-based polymer comprising a terephthalic acid unit (A) and an isophthalic acid unit (B) at a copolymerization proportion (molar ratio) of (A)/(B) = 100/0 to 40/60. The proportion of the heat-resistant thermoplastic polymer in the composite is 30 to 80 wt%.

摘要:
A method of through-thickness reinforcing a laminated material (100) is disclosed, in which a reinforcing element (240) is coated with a thermoplastic layer (250). The reinforcing element is inserted into a base material, and a matrix material (230), such as a polymeric, is included in the base material. The combination is then cured, or heated, such that the thermoplastic layer and the matrix material diffuse into each other, thereby forming an interphase region (260) around the reinforcing element. This interphase region helps to prevent cracks from propagating from the reinforcing element.

A system (100) for making a prepreg composite sheet (300) comprising contoured charges (308) comprises first means (102) for forming precursor outline regions (206) in a resin film layer (200). The system (100) also comprises second means (106) for impregnating a fiber reinforcement (220), comprising fibers (222), with the resin film layer (200), comprising the precursor outline regions (206), to form the prepreg composite sheet (300). The prepreg composite sheet (300), as so formed, comprises non-impregnated outline regions (310) that define the contoured charges (308). The non-impregnated outline regions (310) in the prepreg composite sheet (300) correspond to the precursor outline regions (206) in the resin film layer (200). The system (100) further comprises third means (104) for guiding the fiber reinforcement (220) and the resin film layer (200) to the second means (106). The resin film layer (200) comprises the precursor outline regions (206) formed by first means (102).
摘要:
Die vorliegende Erfindung betrifft ein faserverstärktes Verbundbauteil (1), das zumindest drei Schichten aufweist, umfassend zumindest eine Kernschicht (8) aus textilem Material und mindestens einer oberen und mindestens einer unteren Deckschicht (2, 3) aus kohlenstofffaserverstärktem Kunststoff (4), wobei die Kernschicht (8) mittels eines Harzes (6) mit den Deckschichten (2, 3) verbunden ist. Es ist die Aufgabe der vorliegenden Erfindung, ein faserverstärktes Verbundbauteil bereitzustellen, welches sich kostengünstig herstellen lässt und dabei leichter ist als herkömmliche Kunststoffverbundbauteile, sowie ein besseres Bruchverhalten und gute akustische und Körperschall absorbierende Dämmwirkung zeigt. Die Aufgabe wird gelöst, indem die Kernschicht (8) aus einem komprimierten Vlies (7) aus natürlichen oder synthetischen Fasern oder eine Mischung aus beidem besteht.
摘要:
The present invention provides a method for manufacturing a shaped product constituted by a fiber-reinforced composite material including reinforcing fibers and a thermoplastic resin, the shaped product with maintained isotropy of the fibers to the end thereof even if press-molded under conditions in which charge ratio of a prepreg to a die is low. Specifically, the method includes using a specific prepreg obtained by impregnating the reinforcing fibers with thermoplastic resin, and molding-processing the prepreg under specific conditions.
摘要:
Provided is a molding material comprising a composite of 1 to 50 wt% of a continuous reinforcing fiber bundle (A) and 0.1 to 20 wt% of a poly (phenylene ether ether ketone) oligomer (B); and 30 to 98.9 wt% of a thermoplastic resin (C) adhering to the composite, wherein the component (B) has a melting point of not higher than 270°C. Also provided are a method for molding the molding material, a method for producing the molding material, and a method for producing a fiber-reinforced composite material. A molded article having high heat resistance and dynamic properties can be easily produced without impairing the economic efficiency and productivity during the process for producing a molding material. In addition, a fiber-reinforced composite material can be produced with more ease and high productivity.
摘要:
Apparatus for cutting and/or shearing elongate lengths of fibre into shorter lengths has two adjacent rollers (7) and (8), and means for supplying an elongate length of fibres to the rollers. The rollers (7) and (8) are disposed in a housing (1) and define a nip therebetween. One roller (7) is a pressure roller and the other a blade housing roller. Blades are advanced through slots in the housing of the blade housing roller (8) to cut fibre into shorter lengths and projected towards a delivery slot. Air jets through apertures (20 and 21) in the wall of housing (1) guide shorter fibres out of the housing.

摘要:
Installation de fabrication de pièces en matériau composite, par moulage par transfert de résine. Pour fabriquer à volonté, selon la technique RTM, des pièces composites de grandes dimensions, à fort taux volumique de fibres et des pièces composites de grandes dimensions à faible taux volumique de fibres, il est proposé une installation qui peut fonctionner à débit contrôlé ou à pression contrôlée. Dans les deux cas, la régulation est assurée par une carte en logique floue. A débit contrôlé, la résine est injectée alternativement par deux vérins (40a,40b) commandés par des moteurs dont la vitesse est régulée. A pression contrôlée, la résine est injectée directement depuis des pots d'alimentation (16), alors soumis à une pression régulée par un régulateur d'air (30).
