1. Determinación de la tenacidad a la fractura J en laminados fibra-metal del tipo CARALL con láminas de aluminio 6061 y 1050
ABSTRACT Determination of fracture toughness in hybrid composites, fiber-metal laminates, FML (Fiber Metal Laminates) is very important to perform an analysis of structural integrity to estimate damage tolerance and residual strength of the material against the propagation of a crack This evaluation should be done in both naval and aircraft structures using

2. Assessment of cumulative damage by using ultrasonic C-scan on carbon fiber/epoxy composites under thermal cycling
In recent years, structural composites manufactured by carbon fiber/epoxy laminates have been employed in large scale in aircraft industries. These structures require high strength under severe temperature changes of -56° until 80 °C. Regarding this scenario, the aim of this research was to reproduce thermal stress in the laminate plate developed by temper

3. Charpy impact toughness of conventional and advanced composite laminates for aircraft construction
A weight-based analysis was made of the translaminar Charpy impact toughness performance of conventional and advanced composite materials for aircraft fabrication. The materials were carbon-epoxy (C-Ep) and hybrid fiber-metal TiGr (Titanium-Graphite) laminates. 5 mm-thick three-point bend specimens were tested over a temperature range of -70 to 180 ºC to re

4. Tenacidade à fratura translaminar dinâmica de um laminado híbrido metal-fibra titânio-grafite de grau aeronáutico / Dynamic translaminar fracture toughness of aeronautical grade titanium-graphite hybrid fiber-metal laminate
Several dynamic translaminar fracture toughness criteria have been determined for TiGr hybrid fiber-metal laminate through Linear Elastic (K-factor) and Elastic-Plastic (J-integral) Fracture Mechanics (LEFM and EPFM, respectively) concepts and methodologies. Instrumented Charpy impact testing was carried out over a wide range of temperatures under two loadin

5. A review on the development and properties of continuous fiber/epoxy/aluminum hybrid composites for aircraft structures
Weight reduction and improved damage tolerance characteristics were the prime drivers to develop new family of materials for the aerospace/aeronautical industry. Aiming this objective, a new lightweight Fiber/Metal Laminate (FML) has been developed. The combination of metal and polymer composite laminates can create a synergistic effect on many properties. T
