Carbon outclasses wood in racket paddles: Ratings of expert and intermediate tennis players

Michael Herzog, Olaf Blanke, Véronique Michaud, Christian Fischer

Wooden racket paddles were modified with rubber and carbon fibre laminates and their differences tested in terms of flexural, damping, and coefficient of restitution properties. Four rackets types were designed: a wood reference, wood with rubber, carbon f ...

An axisymmetric stress analysis in a single fibre composite of finite length under a thermal expansion mismatch

John Botsis, Laurent Humbert, Fabiano Colpo

In this paper, an exact solution is derived for the characterization of thermal stresses in a single-fibre composite of finite length. All the required boundary and interfacial conditions of the thermo-elastic problem are thus satisfied exactly. The propos ...

Material and structural performance of fiber-reinforced polymer composites at elevated and high temperatures

Yu Bai

As the range of applications for fiber-reinforced polymer (FRP) composite materials in civil engineering constantly increases, there is more and more concern with regard to their performance in critical environments. The fire behavior of composite material ...

In situ flow stress of pure aluminium constrained by tightly packed alumina fibres

Andreas Mortensen, Ludger Weber, Andreas Rossoll, Benedikt Moser

The in situ matrix flow stress of continuous fibre-reinforced aluminium is measured in tension along the fibre axis. We use a new, tighter, estimate for the effect differential Poisson contraction between fibres and matrix and take into consideration nonli ...

Cellular composites based on continuous fibres and bioresorbable polymers

Pierre-Etienne Bourban

Biocompatible composites, whose porosity and fibre fraction call be tailored over a large range and whose mechanical resistance is comparable to that Of natural bone, were processed with poly(lactic acid) (PLA) and continuous glass fibres. The processing s ...

Monitoring of process induced strains in a single fibre composite using FBG sensor: A methodological study

John Botsis, Joël Cugnoni, Dimitrios Karalekas

A partially embedded long fibre-Bragg grating (FBG) into an epoxy cylindrical specimen is used to monitor the strain distribution evolution along its axis when subjected to subsequent cycles of thermal ageing at 70 and 110 degrees C. Assuming a total volum ...

Cellular thermoplastic composites with microstructural gradients of fibres and porosity

Pierre-Etienne Bourban, Manuel Bühler

New thermoplastic composites with their composition tailored at the yarn level were proposed and successfully prepared. A specific processing method was developed for composites exhibiting different fibre and porosity concentration gradients. Mechanical pr ...

Processing of fibre and porosity gradients in cellular thermoplastic composites

Manuel Bühler

The aim of this study has been to develop processing techniques for novel bioresorbable thermoplastic cellular composites, reinforced with continuous inorganic fibres, for use as biodegradable scaffolds for bone tissue engineering. As the implanted composi ...

Estimation of statistical strength distribution of Carborundum polycrystalline SiC fiber using the single fiber composite with consideration of the matrix hardening

William Curtin

The statistical strength distribution of Carborundum polycrystalline SiC fibers was derived from the fragmentation process in a single fiber/epoxy composite. We conducted Monte Carlo simulations of the fragmentation process using an elastic-plastic hardeni ...

Cellular and fibre-reinforced composites for bone engineering

Pierre-Etienne Bourban, Manuel Bühler

glass fibre composites were successfully prepared. A specific processing method was developed for consolidated composites exhibiting different fibre concentration gradients. As the conditions to prepare PLA polymer foams with specific porosity morphology w ...
