Fiber metal laminates (FML) are composite structures consisting of metals and fiber reinforced plastics (FRP) which have experienced an increasing interest as the choice materials in aerospace automobile industries. Due to a sophisticated built up material, not only design production such is challenging but also its damage detection. This research work focuses on identification FML with guided ...

This research paper focuses on the laminate composites of carbon steel and aluminium alloy using epoxy resin. For making composite metal laminates, compression molding method is used. Press used for sandwiched plates at 90°C 155 seconds. Izod Charpy Impact test were performed laminated its parent material i.e., Carbon Steel (SAE1042) Aluminium Alloy (6061-T6) to made a comparison with investiga...

This research studied the appropriate factors and conditions for laminated bamboo bending by Design of Experiments (DOE). The interested factors affecting the spring back in laminates bamboo were (1) time, (2) thickness, and (3) frequency. This experiment tested the specimen by using high frequency machine and measured its spring back immediately and next 24 hours for comparing the spring back ...

Synopsis A theoretical study of viscoelastic properties of composites is presented with the aim of identifying structures which give rise to a combination of high stiffness and high loss tangent. Laminates with Voigt and Reuss structure, as well as composite materials attaining the Hashin-Shtrikman bounds on stiffness were evaluated via the correspondence principle. Similarly, viscoelastic prop...

In this paper, we present an improved FBG sensor system using a wavelength swept fiber laser(WSFL) for internal strain monitoring of composite laminates. The WSFL provides unique and functional output characteristics useful for sensor interrogation. In addition a realtime signal processing program was made to measure strains. Five FBG sensors in an optical fiber were used to measure internal st...

We have been successful in developing light and durable mirrors made of CFRP (Carbon Fiber Reinforced Plastic) laminates for the reflector of the new CANGAROO-II 7 m telescope. The reflector has a parabolic shape (F/1.1) with a 30 m effective area which consists of 60 small spherical mirrors of CFRP laminates. The orientation of each mirror can be remotely adjusted by stepping motors. After the...
