Abstract:
Embodiments herein relate to a prepreg comprising a thermosetting resin, and reinforcing fibers in the thermosetting resin, wherein when the prepreg is cured in vacuum bag only conditions, and a method of making the same. The method also applies for autoclave processing. Embodiments also relate to a cured fiber reinforced composite material made by thermally curing the prepreg.
Abstract:
A fiber reinforced polymer composition is disclosed. A set of processing parameters is also disclosed which is suitable to process the fiber reinforced polymer composition to manufacture a void-free composite article at a rapid rate and having a similar performance as if it was cured in an autoclave. The composite manufacturing technology utilizes rapid heating/cooling rates and material technologies enabling not only absorption of rapid heat transfers and a suitable balance between cure kinetics and flow characteristics, but also excellent thermal and mechanical performances of the composite article, equivalent or exceeding the properties of an autoclave cured article. The process is applicable to fiber reinforced polymer parts currently made from an autoclave, but which demand faster production rates.
