Lamina properties, lay-up configurations and loading conditions for a range of fibre-reinforced composite laminates

A continuum damage model for composite laminates: Part I - Constitutive model

3D failure criteria for laminated fibre-reinforced composites, based on a physical model for each failure mode and considering non-linear matrix shear behaviour, are developed. Special emphasis is given to compression failure. The physical model for matrix compression failure is based on the Mohr–Coulomb criterion and also predicts the fracture angle. For fibre kinking, an initial fibre-misalignment angle is considered to trigger failure, due to further rotation during the compressive loading. The plane where the kinking takes place is predicted by the model, as well as the kink-band angle. Applications are presented that validate the model against experimental data.

Es wird ein Verfahren zur Herstellung von Bauteilen aus faserverstarktem Kunststoff, bei dem ein mit Fasern belegter Kern in eine Form eingebracht wird und Kunststoff oder Kunststoffvorprodukte in flussiger Form im Wesentlichen senkrecht zu den Fasern in den Formraum eingeleitet wird und anschliesend der eingebrachte Kunststoff aushartet und das Bauteil aus der Form entfernt wird. Dieses Verfahren ermoglicht die Herstellung von dickwandigen Bauteilen mit hoher Laminatqualitat.

of EP1236564A central mandrel (1) is surrounded or wrapped with fibers (4) and molten polymer is fed into the mold space at right angles to the fibers (4) through feed channels (2). The finished component is removed after cooling and hardening. The mandrel can be hollow, with feed channels ending in grooves distributed over the circumference. The mandrel and mold are heated.
