20120219775 | ELECTROMAGNETIC HAZARD PROTECTOR FOR COMPOSITE MATERIALS - A curable flexible electromagnetic hazard resistance laminate, comprising a layer of electrically conductive metal material and thermosetting resin, wherein an external face of the laminate comprises a releasable backing sheet in contact with resin, and the laminate further comprises a substantially non-reshapable sheet of solid material. | 08-30-2012 |
20130005205 | PROCESS FOR MANUFACTURING COMPOSITE MATERIALS - The invention relates to a prepreg comprising a structural layer of conductive fibres comprising thermosetting resin in the interstices, and a first outer layer of resin comprising thermosetting resin, and comprising a population of conductive free filaments located at the interface between the structural layer and the outer resin layer which, when cured under elevated temperature, produces a cured composite material comprising a cured structural layer of packed conductive fibres and a first outer layer of cured resin, the outer layer of cured resin, comprising a proportion of the population of conductive free filaments dispersed therein, and to a process for manufacturing prepregs wherein the electrically conductive fibres pass a fibre disrupting means to cause a proportion of the fibres on an external face of the sheet to become free filaments. | 01-03-2013 |
20130065068 | Composite Tape For Use In Tape Laying Machines - A tape for use in automated tape laying machines that includes a multi-layer substrate composed of a plastic layer that includes at least one plastic film having an outer film surface and an inner film surface. The plastic film is adhered to a fibrous layer so that the inner surface of the fibrous layer is bonded to the inner film surface. An uncured composite material layer composed of a fibrous reinforcement and an uncured resin matrix is releasably adhered to either the plastic layer surface or the outer fiber layer surface to provide a tape suitable for use in an automatic tape layer. | 03-14-2013 |
20130071626 | COMPOSITE MATERIALS - A prepreg comprising a single structural layer of electrically conductive unidirectional fibers and a first outer layer of curable resin substantially free of structural fibers, and optionally a second outer layer of curable resin substantially free of structural fibers, the sum of the thicknesses of the first and second outer resin layers at a given point having an average of at least 10 micrometers and varying over at least the range of from 50% to 120% of the average value, and wherein the first outer layer comprises electrically conductive particles. | 03-21-2013 |
20130122277 | COMPOSITE MATERIALS - A strip of curable prepreg comprising unidirectional fibres aligned with the length of the strip, the fibres being at least partially impregnated with curable thermosetting resin and comprising a flexible polymeric sheet on an outer face of the strip, wherein the strip has a substantially rectangular cross-section defining a width and a thickness of the strip. | 05-16-2013 |
20140316551 | METHOD FOR ON-LINE CONTROL OF A MANUFACTURING PROCESS FOR A MULTICOMPONENT SHEET MATERIAL - A method of controlling a process for the manufacture of a multicomponent sheet material having a desired pre-determined parameter comprising applying an acoustic or an electromagnetic signal to interact with the sheet material whereby the interaction modifies the applied signal, detecting the modified signal, comparing the modified signal or data derived from it with data relating to the pre-determined parameter and modifying at least one step of the process whereby the data relating to the modified signal is modified towards the data relating to the pre-determined parameter. | 10-23-2014 |
20140335361 | FIBRE REINFORCED MATERIALS - 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. | 11-13-2014 |
