Patent number: 11850809Abstract: According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.Type: GrantFiled: November 11, 2021Date of Patent: December 26, 2023Assignee: Johns ManvilleInventors: Mingfu Zhang, Klaus Friedrich Gleich, Asheber Yohannes, Michael John Block, Jawed Asrar, Derek Cooper Bristol, Christopher P Sandoval, Matthew Walp, Edwing Chaparro-Chavez, Stanislav O Kukatin, Albert Patrick Faulkinbury, Christopher McBride, Bradley Ray Lockwood, Nicholas Gene Fitzpatrick

Patent number: 11772336Abstract: According to one embodiment, a system for manufacturing a polymethyl methacrylate (PMMA) prepreg includes a mechanism for continuously moving a fabric or mat and a resin application component that applies a methyl methacrylate (MMA) resin to the fabric or mat. The system also includes a press mechanism that presses the fabric or mat during the continuous movement subsequent to the application of the MMA resin to ensure that the MMA resin fully saturates the fabric or mat. The system further includes a curing oven through which the fabric or mat is continuously moved. The curing oven is maintained at a temperature of between 40° C. and 100° C. to polymerize the MMA resin and thereby form PMMA so that upon exiting the curing oven, the fabric or mat is fully impregnated with PMMA.Type: GrantFiled: August 11, 2020Date of Patent: October 3, 2023Assignee: Johns ManvilleInventors: Mingfu Zhang, Klaus Friedrich Gleich, Asheber Yohannes, Michael John Block, Jawed Asrar, Derek Cooper Bristol, Christopher P Sandoval
