Fibres are generally used as resistance of cracking and strengthening of concrete. In this project, I am going to carry out test on steel fibre reinforced concrete to check the influence of fibres on flexural strength of concrete. According to various research papers, it has been found that steel fibres give the maximum strength in comparison to glass and polypropylene fibres. Hence, in this pr...

Fibre drawing is an important industrial process for synthetic polymers and optical communications. In the manufacture of optical fibres, precise diameter control is critical to waveguide performance, with tolerances in the submicron range that are met through feedback controls on processing conditions. Fluctuations arise from material non-uniformity plague synthetic polymers but not optical si...

A cohort study among 4734 employees at an English glass fibre plant previously reported no excess of lung cancer mortality either overall or when examined in broad occupational groups. To investigate occupation in more detail, and to test the hypothesis that processes producing or using finer (respirable) fibres may be related to a higher risk of lung cancer, a nested case-control study has now...

This study investigates the effect of water absorption on flexural strength kenaf/ glass/unsaturated polyester (UPE) hybrid composite solid round rods used for insulating material applications. Three volume fractions kenaf/glass fibre 20:80 (KGPE20), 30:70 (KGPE30), and 40:60 (KGPE40) with three different arrangement profiles kenaf fibres were fabricated by using pultrusion technique aimed at s...

We utilized fluorescence microscopy and affinity-purified antibodies to probe the form and function of cytoplasmic actin in endothelial cells (EC) recovering from injury and grown on extracellular matrices in vitro. Bovine aortic EC were seeded onto glass microscope coverslips that had been coated with either BSA, fibronectin, type I and III (interstitial) collagens, type IV (basement membrane)...

Self compacting concrete (SCC), developed by Hajime Okamura, has proved to be an excellent concrete in terms of its compactability, flowability and durability apart from strength studies have proved that the effienciency of the SCC can be further increased by introduction of fibres like steel fibres, glass fibres etc. further enhances their toughness, tensile strength, resistance to crack propa...

Abstract A new way of manufacturing continuous fibre-reinforced plastics is the embedding fibres in filament a 3D printer. This method could be used composite materials with thermoplastic matrix containing glass, Kevlar and carbon fibres. paper provides an overview research on mechanical physical properties these parts as well optimisation approaches additively manufactured thermoplastics. Furt...
