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

A curable polymer composition comprising:

Maleimide resins

A curable polymer composition containing: (A) a thermoset benzoxazine resin precursor component; (B) optionally, an aryl sulphone-containing benzoxazine component, and (C) a polyarylsulphone thermoplastic toughening agent, wherein in the absence of component (B), component (C) contains one or more benzoxazine pendant- and/or end-groups.

Benzoxazine resins

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 curable polymer composition containing: (A) a thermoset benzoxazine resin precursor component; (B) optionally, an arylsulphone-containing benzoxazine component, and (C) a polyarylsulphone thermoplastic toughening agent, wherein in the absence of component (B), component (C) contains one or more benzoxazine pendant- and/or end-groups.

A composite material comprising the following components:

Composite materials and their use

A composite material comprising the following components: (a) a first prepreg material with improved resistance to microbuckling and kinkband formation; and (b) a second prepreg material with improved resistance to delamination.

Stiffness-treated honeycomb sandwich structures which exhibit reduced core crush and/or reduced void content are provided. Additionally, stiffness-treated prepreg plies which exhibit increased frictional resistance when disposed on other prepreg plies are also provided. Further, associated starting materials and methods are provided.

Products and method of core crush prevention

A flexible polymer element for a curable composition wherein the flexible polymer element is in solid phase and adapted to undergo at least partial phase transition to fluid phase on contact with a component of the curable composition in which it is soluble at a temperature which is less than the temperature for substantial onset of gelling and/or curing of the curable composition; a method for the preparation thereof, a support structure or carrier for a curable composition comprising the at least one flexible polymer element together with reinforcing fibers, configurations of support structures and carriers, methods for preparation thereof, a curable composition comprising the at least one flexible polymer element or the support structure or carrier and a curable resin matrix, a kit of parts comprising the components thereof and a method for selection thereof, a method for preparation and curing thereof, and a cured composite or resin body obtained thereby, and known and novel uses thereof.

Flexible polymer element as toughening agent in prepregs

A shaped article optionally containing a prepreg, or a composite derived from the shaped article with the prepreg, is prepared from a curable composition derived from the reaction in the presence of a catalyst of epoxy resin having at least 0.05% by weight of an epoxy resin oligomer with a solid rubber possessing at least 1% by weight of reactive groups and which is swellable or soluble in the reaction mixture, in a rubber epoxy resin weight ratio between 1:1 to 1:20, wherein said epoxy resin comprises (a) at least one first epoxy resin having an epoxy functionality of greater than three and (b) at least one second epoxy resin having a functionality of greater than one to three.
