摘要:
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- re info reed thermoplastic composite structures.
摘要:
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.
摘要:
The present invention relates to assembly comprising a first component and a second component, each component comprising a polymer, as well as a film positioned between and bonded to the first component and the second component. The film is such that it comprises at least one poly(ether ketone ketone) (PEKK) polymer and at least one nucleating agent. The assembly has an improved fracture toughness and overall good mechanical properties.
摘要:
A prepared mold tool having a thermoplastic surface layer polymer coating (50) on the mold surface (30) of the mold tool (20) or prepared prepreg (100) having a thermoplastic surface layer polymer coating (50) on the surface of the thermoplastic fiber reinforced prepreg (100) are described that enhance first ply laydown of thermoplastic fiber reinforced composite prepregs (100) onto mold tools (20) 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 (50) 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.
摘要:
Particles of an amine-functionalised polyaryletherketone polymer or copolymer thereof. The amine-functionalised 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).
