| Popis: | The use of fibre-reinforced polymer composites as a lightweight metal replacement for automotive componentry is constantly expanding into new and more challenging application areas (e.g. whole range of under-bonnet, exhaust applications and other automotive components), where service temperatures are not expected to go beyond 150 °C. This study seeks to provide some useful baseline data on the bending stiffness performance of a large range of commercially available composite moulding compounds, in order to provide guidance in selecting appropriate materials for various applications requiring higher operating temperatures, where retention of bending stiffness is a key parameter. Whilst glass transition data can give some indication, this study seeks to go further. Three point bending flexural tests and Dynamic Mechanical Analysis were used to investigate and compare properties both at ambient and 150 °C comparing various composite systems, particularly phenolics, one of the fastest-growing systems in the thermoset moulding compounds market. |
