摘要: In an embodiment, a fiber reinforced composite can comprise a dynamically crosslinked polymer network comprising a polyester matrix and a plurality of crosslinks; a transesterification catalyst; and a fabric layer. A method of making the composite can comprise coating the fabric layer with a composition comprising a pre-crosslinked polymer composition to form a coated fabric; and melt impregnating the coated fabric with the pre-crosslinked polymer composition to form a pre-impregnated composite; and curing the pre-crosslinked polymer composition to form the dynamically crosslinked polymer network.

摘要: Polypropylene-coated functionalized multiwall carbon nanotubes (PP/f-MWNT) comprising functionalized multiwall carbon nanotubes (f-MWNT) in an amount of from about 0.5 wt. % to about 80 wt. %, based on the total weight of the PP/f-MWNT; and polypropylene (PP) in an amount of from about 20 wt. % to about 99.5 wt. %, based on the total weight of the PP/f-MWNT. A method of making PP/f-MWNT comprising (a) contacting pristine multiwall carbon nanotubes (p-MWNT) with nitric acid to produce f-MWNT; (b) contacting at least a portion of the f-MWNT with a first solvent to form a f-MWNT dispersion; (c) contacting PP with a second solvent to form a PP solution; (d) contacting at least a portion of the f-MWNT dispersion with at least a portion of the PP solution to form a PP and f-MWNT suspension; and (e) drying at least a portion of the PP and f-MWNT suspension to form the PP/f-MWNT.

摘要: A global optimization tool may be used to predict characteristics of a multiple ply layered composite as a condition of one or more continuous variables and/or one or more binary variables. For example, the global optimization tool may predict characteristics of a composite for a large range of fiber orientation angles of each of layer of the ply. The optimization tool may include solving a mixed integer nonlinear programming (MINLP) model to obtain a multiple ply layered composite design that is optimized relative to objectives, such as areal weight and cost. Thus, the global optimization tool may be able to identify composite designs with lower areal weight and/or lower cost than the composite designs identified by prior art trial and error methods or heuristic algorithms. When a composite design is identified as meeting certain criteria that are input to the global optimization tool, that composite design may be manufactured.

摘要: This disclosure includes fiber-reinforced composites including and/or formed in part from fibrous non-woven layers, stacks of layers that can be consolidated to form such composites, articles, such as portable electronic device housing panels, including such composites, and methods for making such composites and articles. In some composites, at least one of the non-woven layer(s) includes: (1) a first thermoplastic material that may be present as a first set of resin fibers; (2) a second thermoplastic material that may be present as a second set of resin fibers, the second thermoplastic material having a transition temperature and/or a low-shear viscosity that is higher than that of the first thermoplastic material; (3) a first set of reinforcing fibers; and/or (4) a second set of reinforcing fibers of a type distinct from that of the first set of reinforcing fibers.
