Abstract:
A resin composition for producing a composite part, comprising a first resin component comprising a glycidyl ether epoxy resin, a second resin component comprising a naphthalene based epoxy resin, and an amino-phenyl fluorene curative; wherein the epoxy resin components a) and b) contain up to 33 wt% of the second resin component.
Abstract:
A moulding material comprising a fibrous reinforcement layer and a curable resin matrix. The fibrous reinforcement layer comprises a non-woven fabric comprising a single layer of unidirectional tows arranged at an angle greater than 0° in relation to the lengthwise direction of the fabric and a support structure for maintaining the arrangement of the tows.
Abstract:
A process for the production of a fibre reinforced thermoset resin. The process comprises impregnating a structural fibrous layer with a liquid thermosetting resin composition to form a prepreg,and subsequently curing the thermosetting resin, wherein at the time of impregnation an additional resin component is provided separately to the prepreg, the thermosetting resin composition being free of said additional resin component other than the thermosetting resin, and additional resins are provided to become integrated with the thermosetting resin during curing.
Abstract:
The invention relates to a resin curing agent having the formula (I), wherein R 1 to R 4 are each individually selected from linear or branched C 1 to C 5 alkyl,a process for its manufacture, blends of the reaction products, and two-component curable resin systems.
Abstract:
A structural panel comprising an internal core material having first and second opposing faces, first and second face sheets bonded to the first and second opposing faces respectively, wherein the panel comprises an open-structured sheet, interposed between a first face of the core material and its respective face sheet and the panel comprises less than 200 gsm adhesive.
Abstract:
A curable prepreg comprising a structural layer of conductive fibres and a first outer layer of thermosetting resin, the resin layer comprising thermoplastic particles and glassy carbon particles provides improved electrical conductivity and excellent mechanical properties.
Abstract:
A curable resin with at least one electrically conductive metal region on its surface formed by depositing on the surface a composition comprising activator, contacting the activator with a solution of a reducing agent and a solution of a metal ion, the reducing agent and metal ion undergoing chemical reaction activated by the activator to form an electrically conductive metal region on the surface, and method of forming is provided.
Abstract:
A composite material assembly comprises a) a surface enhancing layer comprising at least one layer of fibres, having a length to width aspect ratio of more than 5:1 and b) a structural layer comprising at least one reinforcing fibre and at least one polymeric matrix.
Abstract:
A resin composition comprising: (i) one or more polymerisable liquid thermoset resin components; (ii) optionally one or more curing agents for said one or more polymerisable liquid resin components; and (iii) at least one gelator, wherein said gelator interacts within said composition to form a gel at ambient temperatures, said gel being thermally reversible such that the gelled composition can undergo a transition from the gelled state to a state of lower viscosity when the composition is treated to facilitate the cure of said polymerisable resin component.
