smoothing tools Explanation: In WordReference.com, the verb "maroufler" means to smooth out from the center toward the edges to remove air bubbles; by extension, I take it to mean in this text "a smoothing out of the various materials used in the manufacturing process. |

debulking elements Explanation: Hello, this is what i found: "Resin is applied to the dry plies after layup is complete (e.g., by means of resin infusion). In a variation known as wet layup, each ply is coated with resin and debulked (compacted) after it is placed. Although debulk can be done by hand with rollers, most fabricators today use a vacuum-bagging technique that involves placing plastic sheet materials over the layup, sealing it at the tool’s edges, adding one or more ports for air hoses and then evacuating air from the space between the sheet and the layup using a vacuum pump). Debulking not only consolidates the layup but also removes air trapped in the resin matrix that would otherwise create undesirable voids (air pockets) in the laminate that could weaken the composite." https://www.compositesworld.com/articles/fabrication-methods "In a process for forming a fiber reinforced composite structure from an uncured composite subassembly of fiber ply material and a resin, the improvement comprising the step of: (a) debulking said composite assembly by applying a combination of a negative pressure on one part of said composite assembly and a positive pressure on another part thereof to thereby remove voids from within said composite assembly prior to curing same." Composite article debulking process : https://patents.google.com/patent/US20080210372A1/en "Hot debulking is a process where multiple layers of composite cloth/resin materials are assembled together into a layup and a vacuum is applied to remove unwanted air and voids within the layup. A variety of BriskHeat heater options can be used to elevate the temperature of the layup to approximately 120°F (49°C). Heat allows the materials to compress easier and limits the amount of voids in the layup to ensure a stronger, more reliable cure." https://www.briskheat.com/applications/composite-curing/tool...
