Oligomer Coupling Agents for Phosphate Based Glass Fibre/pla Composites
Bioabsorbable phosphate glass fibre/polymer composites are being investigated as alternatives to commonly used metal alloy-based bone fracture fixation devices. According to Knowles [1], these ‘Third Generation’ implants remain in the body for the short term necessary for mechanical stabilisation of tissue. In addition the degradation products of the bioabsorbable implants perform an active fun...
متن کاملOligomer Coupling Agents in Phosphate Based Glass Fibre / PLA Composites
Oligomer Coupling Agents in Phosphate Based Glass Fibre/PLA Composites P Haque, AJ Parsons, I Ahmed, DJ Irvine, GS Walker, CD Rudd (Univ of Nottingham) Polylactic acid oligomers as coupling agents have showed potentially higher interfacial shear strength in phosphate based glass fibre/ PLA composites. To influence bonding on the glass fibre surface, the short chain PLA with different end groups...
متن کاملCytocompatibility and Mechanical Properties of Short Phosphate Glass Fibre Reinforced Polylactic Acid (PLA) Composites: Effect of Coupling Agent Mediated Interface
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...
متن کاملEffects of Natural Chitosan as Biopolymer Coupling Agent on the Pyrolysis Kinetics of Wood Flour/ Polyvinyl Chloride Composites
The thermal degradation behavior and pyrolysis kinetic models of wood flour (WF)/PVC composites before and after adding chitosan were studied using thermogravimetry (TGA) and nine common kinetic model functions (f(α)). The results indicated that the thermal degradation temperature of WF/PVC composites was delayed to a higher value after adding chitosan. The first-order reaction order (L1) model...
متن کاملChitosan/hydroxyapatite-based composites
In the past 20 years, there has been a growing trend towards the development and use of biomaterials for the repairing and restoration of damaged bone tissue. The calcium phosphate bioceramics have attracted great attention in the field of orthopaedics because of its similarity to the mineral component of bone tissue. They have been used as granules for example in non-load bearing small implant...
