  • METHODS AND SYSTEMS FOR MAKING REINFORCED THERMOPLASTIC COMPOSITES, AND THE PRODUCTS
    Publication number: 20170267839
    Abstract: Various methods and systems of making inorganic fiber/flake reinforced composites having a thermoplastic matrix are disclosed. The methods use systems similar to those used to make inorganic fiber/flake reinforced products having a thermoset matrix, but the systems and methods are modified to use thermoplastic precursor monomer(s) followed by in situ polymerization of the monomer(s) during and/or following forming of the desired shape of the products. These methods permit the manufacture of superior inorganic fiber reinforced thermoplastic matrix composites in large and very large shapes heretofore not possible, or practical.

  • Flame resistant laminate
    Patent number: 9650783
    Abstract: A flame resistant laminate is described, which distinguishes itself by its low heating value ?3 MJ/kg according to ISO 1716 and thanks to its special multilayer structure has excellent mechanical characteristics and an extraordinarily good stability under changing climatic conditions (hot/humid/cold/dry). The laminate according to the invention comprises several mineral and glass fiber non-woven fabrics with different functionalities and components. This includes high-filled non-woven fabrics, B-stage binders and other additives. Its great mechanical strength as well as the extraordinarily good stability under changing climatic conditions (hot/humid/cold/dry) allow its reasonable use in many areas where until now exclusively laminates according to EN 438 are used and beyond.

  • SYSTEM FOR PRODUCING A FULLY IMPREGNATED THERMOPLASTIC PREPREG
    Publication number: 20170120544
    Abstract: 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.
