Принадлежит: Hexcel Composites Ltd

A resin composition that is storable at ambient temperatures. The resin composition forms a cured resin when exposed to a curing agent and heated to a curing temperature that is relatively close to ambient temperature. The resin composition includes a resin component that is composed of a liquid part that is made up of one or more liquid thermosetting resins and a solid part that includes particles of one or more solid thermosetting resins. The liquid part further includes a gelation agent that is present in a sufficient amount to maintain the particles in suspension within the liquid part at ambient temperatures. The viscosity of the resin component changes from a high viscosity state to a low viscosity state when the temperature is increased from ambient temperature to the curing temperature.

Ornamentation Of Composites

Номер: US20120313281A1
Автор: Gosakan Aravamudan

A method for decorating a composite placed in a mold in a resin transfer molding process includes selectively depositing unbonded pigments on one or more areas of a preform of the composite, and injecting a resin into the mold via one or more resin input ports operably connected to the mold. The injected resin carries the selectively deposited unbonded pigments on a path on one or more areas of the preform of the composite along a direction of flow of the injected resin, thereby creating ornamental pigment flow patterns in the composite for decorating the composite. The method also creates bands of ornamental pigment flow patterns by depositing the unbonded pigments on a transfer medium positioned on the composite, positioning the transfer medium in proximity to the resin input ports, and selectively injecting the resin onto the transfer medium deposited with the unbonded pigments, via the resin input ports.

A prepreg that contains a plurality of unidirectionally aligned continuous fibers embedded within a thermoplastic polymer matrix is provided. In addition to continuous fibers, the prepreg also contains a plurality of long fibers that are combined with the continuous fibers so that they are randomly distributed within the thermoplastic matrix. As a result, at least a portion of the long fibers become oriented at an angle (e.g., perpendicular) relative to the direction of the continuous fibers. Through such orientation, the long fibers can substantially increase the mechanical properties of the prepreg in the transverse direction (e.g., strength) and thus achieve a more isotropic material. Although unique isotropic prepregs are one aspect of the present invention, it should be understood that this is not a requirement. In fact, one notable feature of the present invention is the ability to tailor the mechanical properties of the prepreg for an intended application by selectively controlling certain process parameters, such as the type of long fibers employed, the type of continuous fibers employed, the concentration of the long fibers, the concentration of the continuous fibers, the thermoplastic resin(s) employed, etc. 1.
