本发明公开了一种聚双环戊二烯轻量化车门,包括聚双环戊二烯车门外皮和聚双环戊二烯车门内饰,聚双环戊二烯车门外皮与聚双环戊二烯车门内饰连接。聚双环戊二烯车门外皮和聚双环戊二烯车门内饰均为一体浇注成型。聚双环戊二烯车门外皮和聚双环戊二烯车门内饰之间也可以设置车门骨架。本发明提供的车门克服了现有技术的不足,将传统的金属车门改为较轻的聚双环戊二烯车门,且可 The invention discloses a poly dicyclopentadiene lightweight door, which comprises a poly dicyclopentadiene door cover and a poly dicyclopentadiene door trim, wherein the poly dicyclopentadiene door cover is connected with the poly dicyclopentadiene door interiors . Poly dicyclopentadiene door skin and poly dicyclopentadiene door trim are one of the pouring molding. Door frames can also be provided between the poly dicyclopentadiene door skin and the poly dicyclopentadiene door trim. The vehicle door provided by the invention overcomes the deficiencies of the prior art by changing the traditional metal door to a lighter poly dicyclopentadiene door,
