The HEPHAISTOS system integrates advantageously the basic processing steps as tooling, tempering of the resin and lay up, the impregnation of the fibers, pre-forming techniques as well as finally the process curing of the composite structures. Composites for aerospace applications in prepreg and wet technology have been successfully fabricated and investigated for quality and certification issu...

An analytical model to predict the linear viscoelastic behavior of thin-walled laminated fiber-reinforced plastic (FRP) composite beams is presented. Using the correspondence principle, this new model integrates micro/macro-mechanics of composites and mechanics of thin-walled laminated beams to perform beam. analyses in the Laplace or Carson domains. The analytical expressions for beam relaxati...

The paper provides mathematical modelling for prefabricated timber-framed walls composed of a timber frame and two different types of sheathing boards. Since by wood-based boards (WBB) the tensile strength is similar to the compressive one, there are practically no cracks appearing in the boards. On the other hand, in case of fibre-plaster sheathing boards (FPB) the tensile strength is approxim...

This paper deals with the study of machinability of GFRP composite tubes of different fiber orientation angle vary from 30 to 90. Machining studies were carried out on an all geared lathe using three different cutting tools: namely Carbide (K-20), Cubic Boron Nitride (CBN) and Poly-Crystalline Diamond (PCD). Experiments were conducted based on the established Taguchi’s Design of Experiments (DO...

Glass fibre reinforced polymer (GFRP) profiles are finding increasing applications in civil engineering structures, owing to the several advantages they offer over traditional materials. However, due to the combustible nature of their polymer matrix, there are well-founded concerns about their behaviour at elevated temperature and under exposure to fire. These concerns are hindering the widespr...

The production of carbon fiber-reinforced plastic (CFRP) is currently changing from a highly manual and expensive to an automated process. However for automated production of CFRP parts new sensor systems for quality control are required. In this article we present a photometric stereo inspection system that is able to automatically evaluate critical quality criteria of carbon fiber fabrics. Ba...

Gears are an integral and necessary component in our everyday lives. Most of the work performed in plastic and metal but very few works available in combine effect of plastic and metal gears. The main problem while referring plastic gear is the bending strength and in case of metal gear is cost. Hence, the work is performed on metal plastic composite gear to get benefit of both. Here use the co...

Short banana fiber reinforced composites have been prepared in laboratory to determine mechanical properties. It has been observed that as soon as the percentage of the banana fiber increases slightly there is a tremendous increase in ultimate tensile strength, % of strain and young modulus of elasticity. Reinforcement of banana fibers in epoxy resin increases stiffness and decreases damping pr...
