Fibre Reinforced Materials and Methods o Making and Using Them

Specification describes material for use in forming fibre reinforced structures comprising longitudinally extending fibre reinforcing material having a thermoplastics resin intimately associated therewith along the length thereof. The thermo-plastics resin may be formed as a coating along the length of the fibre and/or as part of a composite fibre. The coating may be applied to the fibre by passing the fibre through an extrusion press or bath of molten thermo-plastics material. The material so formed may be used to form fabric by weaving, knitting or the like or may be used directly subsequent to being chopped into short lengths. Layers of the fabric may be laminated by stitching with lengths of thermoplastics coated fibre. Various structures for use in the aircraft industry, and the methods of making those structures from the material, e.g. by moulding, are described. ...

Improvements relating to the impregnation of rovings with liquids

[Also in Division B5] A method of impregnating a roving 8, e.g. of glass fibres, with a liquid containing a permanent impregnant, e.g. a solution of a polyester or of an epoxy resin, comprises passing the roving 8 longitudinally via inlet orifice 20 and outlet orifice 21 through a chamber 6 to which the liquid is fed at high pressure, so that the liquid establishes a front 16 in the roving by which all air is forced out of the roving. The emergent roving 9 comprises a continuous solid structure of fibres and impregnant. An empirical formula based on the speed of the roving and the dimensions of the chamber 6 and of the roving enable the minimum pressure to be calculated. A pressure of several hundred atmospheres is mentioned. The relative dimensions of the orifices 20, 21 may be chosen to control the resistance to movement of the roving ...

A method of forming fibrous mats consists in entraining dissimilar fibrous materials separately in a plurality of air streams down hollow shoots and depositing the fibrous material successively on to a movable support or conveyer, whereby a mat of superposed layers of dissimilar fibrous material is formed with the fibres of adjacent layers interlacing at random directions to form an interfacially interlaced stratified mat. Preferably the support or conveyer is in continuous motion during the deposition of the fibrous material and the hollow shoots oscillated transversely to the movement of the conveyer. Air streams containing entrained resin binder may be directed concurrently with the air streams entraining the fibrous material. The fibrous material from different shoots may differ in chemical composition or in physical texture and the rate of discharge from each ...

A tape comprises a plurality of metal wires 10 bonded together in parallel relationship in a plane, each of said wires having at least one flat surface 11. The wires 10, which may also have an arcuate surface 12 are bonded together by spaced welds 14 or by enclosing them in spaced flexible strips 16 or by embedding the wires in a plastic mass (Fig. 9), e.g. cellulose acetate, cellulose acetate butyrate, ethyl cellulose or a natural or synthetic resin such as polyvinyl chloride or a matrix of metal 17, e.g. lead, tin, zinc or solder (Fig. 10). The flat surface of the wire is provided with a multiplicity of grooves or striations.

Glass fibres are interbonded in a mat by impregnating the mat with an aqueous dispersion of synthetic-resin particles of size between 50 and 5 microns, and heating the mat to drive off water and cause the synthetic-resin particles to stick to the fibres and bind them together. As shown, glass is melted in a tank 10 and drawn into small streams 12 which are attenuated and solidified. They then pass over an applicator 13 for lubricant such as a water solution of distearate condensate of tetraethylenepentamine pelargonate, or even plain water. They then pass over a gathering shoe 14 and between puller wheels 15, and are projected on to a deflector trough 16. This is pivoted and oscillates to deflect the fibres on to but across the full width of the conveyer 18 where they form the mat 19. Alternatively the mat can be made of chopped strands or by steam blowing. The mat ...

Sheet material having a hard, resistant surface is made by coating one face of absorptive sheet material such as paper or fabric with a thermo-setting resin in liquid state which penetrates only partly through the sheet, drying, with the aid of heat, subjecting the still hot or reheated material to heat and pressure to cure the resin, and immediately winding the material into a roll with the impregnated surface facing outwardly. Alternatively, an impregnated strip and an mitreated strip of absorptive material may be brought together and subjected jointly to the drying and curing steps whereby they are united together, and the resulting laminated strip is wound into a roll with the resin-treated surface on the outside. An adhesive-coated metal strip may be interposed between the impregnated and unimpregnated strips. The surface of ...

Method for connecting reinforcing fiber bundles, method for producing long fiber reinforced thermoplastic resin pellet, and wound body

A method for connecting a tail end portion of a reinforcing fiber bundle of a preceding wound body to a front end portion of a reinforcing fiber bundle unwound from a new wound body by blowing pressurized air to both of the ends to unravel and entwine both of the reinforcing fiber bundles, wherein the method includes a preparation step for adjusting the amount of a sizing agent contained in the front end of the reinforcing fiber bundle unwound from the new wound body and the tail end of the preceding wound body to not less than 0 wt % and not more than 4 wt %, and the reinforcing fiber bundles are connected after the preparation step. It is thus possible for the reinforcing fiber bundle at the time of producing a long fiber reinforced thermoplastic resin pellet that is a material for the pellet to have a required connection strength, and to avoid the occurrence of interruption due to breakage, and accordingly allowing improvement in the production efficiency of the long fiber reinforced thermoplastic resin pellet, etc.

A hollow lineal profile ( 16 ) formed from a continuous fiber reinforced ribbon (“CFRT”) that contains a plurality of continuous fibers embedded within a first thermoplastic polymer matrix ( 6 ). To enhance the tensile strength of the profile, the continuous fibers are aligned within the ribbon in a substantially longitudinal direction (e.g., the direction of pultrusion). In addition to continuous fibers, the hollow profile of the present invention also contains a plurality of long fibers that may be optionally embedded within a second thermoplastic matrix to form a long fiber reinforced thermoplastic (“LFRT”) ( 4 ). The long fibers may be incorporated into the continuous fiber ribbon or formed as a separate layer of the profile. Regardless, at least a portion of the long fibers are oriented at an angle (e.g., 90°) to the longitudinal direction to provide increased transverse strength to the profile.

PROCESS AND DEVICE FOR THE PRODUCTION OF A FIBRE-COMPOSITE MATERIAL
