Abstract: Polydicyclopentadiene (PDCPD) is a kind of thermosetting polymeric material with excellent mechanical properties, low density and easy processing, which can replace some steel plate, castings and glass steel parts for agricultural vehicles, engineering vehicles, heavy trucks and other applications. Fiber reinforced PDCPD composites can show stronger mechanical properties and may extend to wider application including but not limited to various vehicle parts, rail transit, wind power, photovoltaic parts, hydrogen storage, etc. However, the polarity of PDCPD itself is low, and the interfacial bonding between commercial fabrics and PDCPD is poor, which limits the application of fiber reinforced PDCPD composites. The research progress of fiber-reinforced PDCPD materials in recent years was reviewed. The approaches to improve the interfacial bonding property of the carbon and glass fiber reinforced PDCPD materials were discussed. And future modifications of the fiber-reinforced PDCPD composites were prospected.
