Problems solved by technology

Unfortunately, epoxy binders or nylons have limited properties that limit the range of temperatures and pressures required to form ply stacks of dry fiber preforms
Using a soldering iron to locally adhere composite plies together is a time-consuming process that adds to the production time of composite structures

Embodiment Construction

[0094] Referring now to the drawings, in which are shown for purposes of illustrating various embodiments of the present disclosure, figure 1 Shown in is a block diagram of a composite structure 100 . The composite structure 100 may be formed as a composite layup 102 or composite laminate 104 including a plurality of composite plies 106 . The composite ply 106 may include fiber bundles 114 embedded within a resin 112 . Fiber bundle 114 may be composed of a plurality of reinforcing fiber filaments 116 . In some examples, reinforcing filaments 116 may include a size 138 (see, e.g., Figure 7 ) or a protective coating that may be applied to the filament surfaces 118 of the reinforcing filaments 116 during manufacture of the reinforcing filaments 116. The size 138 can be of a size 140 ( Figure 7 ) is a surface modification deposited on the reinforcement surface along the length of the reinforcement filament 116. The size 138 may improve the bond between the reinforcing fiber...

Abstract

A composite fiber may include at least one reinforcing fiber filament formed from a first material. The second material may be deposited onto the at least one reinforcing fiber filament in an orderly manner in an embossed pattern such that at least one of the length, width and thickness of the second material is on the surface of the at least one reinforcing fiber filament Variety. The embossed pattern can alter one or more properties of a composite structure comprising composite fibers.

Description

technical field [0001] The present disclosure relates generally to composite structures and, more particularly, to embossing modifying materials onto composite laminates. Background technique [0002] Composite structures typically include continuous reinforcing fibers embedded in a resin matrix. A composite laminate is a type of composite structure comprising a layup of composite plies arranged in a stack. Individual composite plies in a composite layup may be pre-impregnated with resin (eg, pre-preg plies) prior to stacking. The stack of prepreg plies may be arranged such that the continuous reinforcing fibers in each ply are oriented in a particular direction. Heat may be applied to the stack to reduce the viscosity of the resin in each ply, thereby allowing the resin to mix with that of adjacent plies, while the stack is consolidated under pressure to remove voids within the composite layup and Volatiles of composite layups. The resin can be cured or consolidated int...
