Epoxy report aids composite choices
Over the last three decades the use of PMC has increased tremendously and this dramatic growth is expected to continue in the future.
Smithers Rapra Technology has published a new review report: Epoxy Composites: Impact Resistance and Flame Retardancy The urge to improve the properties of composite materials, has prompted materials scientists to investigate composites with lower and lower re-inforcement size, leading to the development of microcomposites

Rapra Technology helps with the vision
Rapra Technology has been working with the Manufacturing Advisory Service - West Midlands (MAS-WM) in order to enable a leading manufacturer of surgical instruments diversify and expand its range.
Polymer matrix composite (PMC) can be processed at a much lower temperature than composites with other types of matrix.
Depending on the type of polymer matrices, PMCs are classified as thermosetting or thermoplastic composites.
Over the last three decades the use of PMC has increased tremendously and this dramatic growth is expected to continue in the future.
The composites possess many useful properties, including high specific stiffness and strength, dimensional stability, adequate electrical properties and excellent corrosion resistance.
They allow easy transportability, high payloads on vehicles, low stress for rotating parts, and high ranges for rockets and missiles, which makes them attractive for both the civil and defence applications.
The composite industry is currently dominated by thermosetting resins such as epoxy, vinyl ester, unsaturated polyester, phenolic, polyimides and cyanate ester.
This is because of their availability, relative ease of processing, lower cost of capital equipment for processing and low material cost.
Topics covered in the report include: thermosetting composites; epoxy resins; impact resistant epoxy composites; modification of epoxy matrix; nano-re-inforcement of epoxy; simultaneous nano-re-inforcement and toughening; fire retardant epoxy composites; and fire retardant resin composition.
The review is supported by an indexed section containing approximately 300 key references and abstracts selected from the Polymer Library.
