This article introduces a kind of composite material made kapok fibre and polycaprolactone by the hot-pressing method. The effects volume density, mass fraction fibre, thickness on sound-absorption performance composites were researched using single-factor experiment. was investigated transfer function Under optimal process parameters, when density 0.172 g/cm3, 40%, 2 cm, reached maximum coeffi...

Novel aluminised E-glass fibre reinforced unsaturated polyester composites, originally formulated for enhanced thermal and electrical shielding properties were evaluated in terms of their thermal performance. The thermal degradation of these specimens was analysed using a thermogravimetric analyser (TGA). The samples were heated from ambient temperature to 500 1C at a heating rate of 20 1C/min....

A procedure is presented for characterisation of fibre misalignment in composites. It is based on analysis of low magnification images in which the local fibre direction can be inferred from the orientation of elongated features in the image. Specimen preparation and image analysis procedures are presented and their usage is illustrated by application to a carbon fibre composite. Factors affect...

Residual stresses in fibre reinforced composites can give rise to a number of undesired effects such as loss of dimensional stability and premature fracture. Hence, there is significant merit in developing processing techniques to mitigate the development of residual stresses. However, tracking and quantifying the development of these fabrication-induced stresses in real-time using conventional...

This paper reports the sensor integration method into carbon composites for the development of Structural Health Monitoring (SHM). Early detection and long term monitoring of the specific properties of composites will improve the security and prolong the time of service 1 . The core function of SHM is the damage detection and identification at elevated temperatures, over loads and corrosion. Va...

Glass-fibre reinforced polymer matrix composites exhibit superior properties to traditional materials. Thus, they have found a broad variety of applications in modern industry. For process development and quality control sophisticated three-dimensional methods for non-destructive characterization are needed. X-ray computed tomography (CT) is a powerful radiographic nondestructive-testing method...

Abstract Natural fibre–reinforced composites are more sustainable than other with respect to the raw materials. Their properties attractive due high specific properties, and especially so wherever damping is valued. As interphase between fibre matrix region of highest stresses, a strong bond essential for any composites’ properties. The present study compares two methods determining interfacial...
