BACKGROUND: A gap still exists between in vitro and clinical studies concerning the biocompatibility of the material in the oral environment and their potential to cause immunological undesirable side effects. The uses of glass fibres to improve the mecha... see more

A number of analytical techniques were applied to investigate changes to the surface of unsized boron-free E-glass fibres after thermal conditioning at temperatures up to 700 °C. Novel systematic studies were carried out to investigate the fundamental str... see more

At present time and for several years, some different concretes have been developed for special purpase. The most used procedure is to modify the cementbased matrix, to improve some properties, subtitrating components or using admixtures, additions or bot... see more

This paper summarizes the research that is being carried out at the Universities of Coimbra and Rio de Janeiro, on fibre reinforced concretes at high temperatures. Several high strength concrete compositions reinforced with fibres (polypropylene, steel an... see more

It is well known that injection of glass fibre–reinforced plastics (GFRP) causes abrasive wear in moulds’ cavities and runners. Physical vapour deposition (PVD) coatings are intensively used to improve the wear resistance of different tools, also being on... see more

Bamboo reinforced epoxy have adequate properties to attract its use as structural material in engineering applications. Research materials on bamboo-plastics composites are not common. This work is an experimental study of bamboo-epoxy composite on which ... see more

Increasing importance is being attached to materials in the life-cycle of a building. In the Netherlands, material life-cycle assessments (LCA) are now mandatory for almost all new buildings, on which basis the building is then awarded a building environm... see more

While plain concrete has poor tensile strength, low resistant to tensile cracking, low ductility, so its capacity to absorb energy is limited. Internal micro cracks are inherently present in concrete and its poor tensile strength is due to propagation of ... see more

An experimental study has been carried out to evaluate the influence of confinement ofalumina ceramic tiles through polymer restraint, on its ballistic performance. Tiles of 99.5 per centpurity alumina were subjected to ballistic impact against 7.62 mm ar... see more
