Publication number: 20110049426Abstract: Use of a resin system for making a composite material in a liquid moulding process. The resin system comprises an epoxy component and at least one curing agent, and at least 35 wt. % of the epoxy component is one or more naphthalene based epoxy resin. There is also provided a cured composite material, and a method of making the cured composite material in a liquid moulding process which comprises placing fibre reinforcement and the resin system in a mould and curing. The resin system and the methods of making a cured composite material are particularly applicable to liquid moulding processed such as resin trans moulding (RTM), vacuum assisted resin transfer moulding (VARTM), Seeman composite resin infusion moulding (SCRIMP), resin infusion under flexible tooling (RIFT), and liquid resin infusion (LRI).Type: ApplicationFiled: May 14, 2009Publication date: March 3, 2011Applicant: Hexcel Composites, Ltd.Inventors: Neal Patel, Steve Mortimer

Patent number: 6391436Abstract: The invention provides a method of forming a void-free laminate, comprising the steps of: (a) enclosing a partially impregnated prepreg in a vacuum envelope, said partially impregnated prepreg comprising a fiber layer partially impregnated with a resin composition; and (b) heating said partially impregnated prepreg under vacuum to withdraw air present in said partially impregnated prepreg and to cause said resin composition (i) to fully infuse into said fiber layer and (ii) to cure thereby forming said void-free laminate. The present invention further provides novel combinations of modified epoxy resins that may be employed with the methods disclosed. The void-free laminates may be utilized for the manufacture of parts for the aerospace and aircraft industries.Type: GrantFiled: May 20, 1999Date of Patent: May 21, 2002Assignee: Cytec Technology Corp.Inventors: Guo Feng Xu, Linas Repecka, Steve Mortimer, Steve Peake, Jack Boyd
