Poly(ether ketone ketone) (PEKK) composites include reinforcing fibers in a PEKK polymer matrix that includes a PEKK polymer. It was surprisingly discovered that by washing unneutralized PEKK polymer powder with an acid or base, the melt stability of the PEKK polymers can be improved, as compared with PEKK polymers prepared by conventional methods. The PEKK composites are especially well-suited for fabrication of thick composite parts where melt stability is especially important.

Poly(ether ketone ketone) (PEKK) composites

The present invention relates to poly(ether ketone ketone) (PEKK) polymers, a method for the manufacture thereof, to articles and composites made therefrom, to methods of making the composites, and composite articles including the PEKK composites. It was surprisingly discovered that by synthesizing the PEKK polymers from low-metal monomers and selectively controlling the relative amounts of reactants during the synthesis, PEKK polymers having unexpectedly improved melt stability can be obtained. The PEKK composites including the PEKK polymers are especially well-suited for fabrication of thick composite parts where melt stability of the polymer matrix is important.

Poly(ether ketone ketone) (PEKK) polymer and composites

Composite materials and structural adhesives containing particles of functionalized polymers as a toughening agent. The particles are composed of functionalized polyaryletherketone (PAEK) polymer or copolymer thereof that contain chemical functional groups capable of reacting with a thermoset resin component to form covalent bonds.

Functionalized polymer particles for use as toughening agent

The present invention generally relates a composite material containing fibers and a resin matrix that comprises a PEEK-PEoEK copolymer having Rand Rrepeat units in a molar ratio R/Rranging from 95/5 to 5/95 in contact with at least a part of the surface of such fibers. The present invention also relates to methods for making such composite materials, shaped articles made from such composite materials, and methods of making such articles.

Fiber reinforced thermoplastic matrix composite material

A prepared mold tool having a thermoplastic surface layer polymer coating on the mold surface of the mold tool or prepared prepreg having a thermoplastic surface layer polymer coating on the surface of the thermoplastic fiber reinforced prepreg are described that enhance first ply laydown of thermoplastic fiber reinforced composite prepregs onto mold tools for prepreg forming or in situ tape placement. Resulting thermoplastic fiber reinforced composite parts from a thermoplastic fiber reinforced thermoplastic composite material having structural reinforcement fibers with one or more high performance polymers, and a thermoplastic surface layer polymer coating which forms a polymer blend with the high performance polymers of the thermoplastic fiber reinforced composite material thereby imparting improved properties, and methods for making and using same, are provided herein.

Surface engineering of thermoplastic materials and tooling

Surface-treated polymeric particles which are dispersible in water or an aqueous solution without the aid of any surfactant. Surface treatment of hydrophobic polymeric particles is carried out to increase the surface energy and to render the surfaces of the particles hydrophilic, thereby eliminating the need for a surfactant to disperse the polymeric particles in water or an aqueous solution. As such, a surfactantless slurry can be formed from the surface-treated particles for the fabrication of fiber-reinforced thermoplastic composite structures.

Surface-treated polymeric particles, slurry containing the same, and use thereof

Particles of an amine-functionalized polyaryletherketone polymer or copolymer thereof. The amine-functionalized polyaryletherketone polymer or copolymer thereof is selected from the group consisting of: polyaryletherketone polymer with terminal amine or protected amine functional group(s); polyaryletherketone-imide copoplymer with terminal amine or protected amine functional group(s); and polyaryletherketone-sulphone copolymer with terminal amine or protected amine functional group(s).

Particulate amine-functionalized polyaryletherketone polymer and copolymers thereof

A plurality of thermoplastic composite structures are laminated to each other in a lay-up arrangement to form a laminate. Each thermoplastic composite structure is composed of a core composite layer and a surface layer polymer applied to opposing surfaces of the core composite layer. The core composite layer is composed of a fibrous substrate and one or more high performance polymers, which crystallize at a faster rate than the surface layer polymer.

Thermoplastic composites and methods of making and using same

Thermoplastic composites having a core composite layer including a fibrous substrate and one or more high performance polymer, and a surface layer polymer applied to at least one surface of the core composite layer, which forms a polymer blend with the high performance polymer thereby imparting improved toughness and processing times, and methods for making and using same, are provided herein.
