Optimization of the stress transfer capability of the fibre-matrix interphase region is critical to achieving the required performance level in thermoplastic matrix composites. Despite the ever increasing diversity of the reinforcements available for polymer composites, glass fibres still account for 95% of fibre reinforcements used in the composites industry, primarily due to of their highly a...

Reinforcement of flexible fibre reinforced plastic (FRP) composites with standard textile fibres is a potential low cost solution to less critical loading applications. The mechanical behaviour of FRPs based on mechanically bonded nonwoven preforms composed of either low or high modulus fibres in a thermoplastic polyurethane (TPU) matrix were compared following compression moulding. Nonwoven pr...

Bioresorbable phosphate glass fibre reinforced polyester composites have been investigated as replacement for some traditional metallic orthopaedic implants, such as bone fracture fixation plates. However, composites tested revealed loss of the interfacial integrity after immersion within aqueous media which resulted in rapid loss of mechanical properties. Physical modification of fibres to cha...

Natural fibers are gaining the interest of scientist and engineering in packaging, low cost housing and other general applications. In the present study, adhesive tensile and moisture absorption properties of randomly distributed areca fibre and maize powder reinforced urea formaldehyde composites has been investigated. Composites were prepared by hydraulic hot press at 150C and 100 bar pressur...

In this study three chemical agents Amino-propyl-triethoxy-silane (APS), sorbitol ended PLA oligomer (SPLA) and Hexamethylene diisocyanate (HDI) were identified to be used as coupling agents to react with the phosphate glass fibre (PGF) reinforcement and the polylactic acid (PLA) polymer matrix of the composite. Composites were prepared with short chopped strand fibres (l = 20 mm, ϕ = 20 µm) in...

Many of the advances in material performance over the last decade can be attributed to developments in multicomponent polymer systems and specifically, to multiphase materials such as incompatible polymer blends and fibre-reinforced composites. In these types of material, performance properties are often dominated by the interphase that defines the transition region from one pure phase to anoth...

applications of thermoplastic composites have developed extensively. the thermoplastic composites in comparison with the thermoset composites have many advantages. thermoplastic composites can be melted and remolded many times. the duration of manufacturing process of these composites is short, producing very tough material, and the welding ability and multiple recyclings are their further adva...

Thermophysical properties such as, effective thermal conductivity (A,,) and effective thermal diffusivity (Xc) of untreated reinforced phenol formaldehyde with different weight per centages of oil-palmfibre (x) are measured simultaneously using the transient plane source (TPS) technique between 80 to 120"C. The composites investigated contain 20, 30 and 50 weight per centage of oil-palm-fibre. ...

This paper presents an experimental study on the static and dynamic mechanical properties of nonwoven based flax fibre reinforced polypropylene composites. The effect of zein modification on flax fibres is also reported. Flax nonwovens were treated with zein coupling agent, which is a protein extracted from corn. Composites were prepared using nonwovens treated with zein solution. The tensile, ...

In brittle materials such as concrete and ceramics, fibre reinforcement has been widely accepted as an effective way of improving their strength and toughness. In addition, a notable pseudo strain-hardening phenomenon can contribute to a significantly enhanced ductility of the composite when an adequately designed fibre system is used. This condition was first proposed by Aveston et al. [1], an...
