摘要： A method of manufacturing a composite component according to various aspects of the present disclosure includes disposing a fiber preform in a mold. The fiber preform includes a first portion having a first edge and a second portion having a second edge. The first edge and the second edge cooperate to at least partially define a gap. One of the first portion or the second portion includes a first ferromagnetic material and the other of the first portion or the second portion includes a first magnetic or magnetizable component. The method further includes closing the gap by generating a magnetic field from the first magnetic or magnetizable component. The method further includes injecting a polymer precursor into the mold. The method further includes forming the composite component by solidifying the polymer precursor to form a polymer. The composite component includes the fiber preform and the polymer.

摘要： A method is provided for forming a near-net thermoplastic composite component includes co-spraying a mixture comprising a thermoplastic polymer material and a chopped reinforcing material deposited onto at least one region associated with a tool having a first temperature and defining a near-net component shape. The mixture and adjacent tool is heated to a second temperature while the mixture is on the tool. The first temperature is below the solidification temperature of the thermoplastic polymer material and the second temperature is above the solidification temperature. Then, the mixture is exposed to a negative pressure to promote removal of gases from the mixture and put under compressive force to densify the mixture. The thermoplastic polymer material melts and flows. The tool is cooled to the first temperature and removing the mixture to form the near-net thermoplastic composite component having randomly oriented chopped reinforcement material distributed within a thermoplastic polymer matrix.

摘要： Methods of repairing a defect in a polymeric composite structure are provided. The methods include disposing a patch over a defect in a polymeric composite structure; disposing a textured sheet over the polymeric patch, applying pressure to the polymeric patch and the textured sheet; and heating the polymeric patch. The textured sheet has a surface texture that is a negative of a surface texture of the polymeric composite structure.

摘要： An assembly for a vehicle having reduced galvanic corrosion includes a first component defining at least one interface region that includes a carbon-fiber reinforced polymeric composite (CFRP) and a first material present in the at least one interface region and having a first electrochemical potential. A second component has a second material and is in contact with the at least one interface region of the first component. The second material has a second electrochemical potential different than the first electrochemical potential. In this manner, in the presence of an electrolyte the first material may be either less noble than the second material and serve as a sacrificial material or alternatively more noble to the second material reducing a driving force for corrosion. Methods of reducing galvanic corrosion in an assembly (e.g., for a vehicle) are also provided.

摘要： An underbody assembly for a vehicle includes a plurality of polymer-fiber composite components. The polymer-fiber composite components include a base and a first reinforcement. The base includes a first side and a second side. The base is configured to extend in a longitudinal direction between a front of the vehicle and a rear of the vehicle. The first reinforcement is coupled to the base. The first reinforcement includes a first elongated ridge and a first elongated trough. The first elongated trough is disposed adjacent to the first elongated ridge. The first elongated ridge and the first elongated trough each extend transversely between the first side of the base and the second side of the base. In various aspects, the underbody assembly consists essentially of the polymer-fiber composite components.

摘要： An energy-absorbing assembly includes a housing and a plurality of discrete energy-absorbing elements. The housing includes a first wall and a second wall. The first wall and the second wall are spaced apart from one another to at least partially define an interior compartment. Each element of the plurality of energy-absorbing elements includes a polymer and a plurality of reinforcing fibers. The plurality of energy-absorbing elements is at least partially disposed within the interior compartment and fixed to the housing. Each energy-absorbing element of the plurality of energy-absorbing elements includes an elongated hollow structure extending between a first end and a second end. Each elongated hollow structure defines a longitudinal axis extending nonparallel to at least one of the first wall and the second wall. In various alternative aspects, each energy-absorbing element may include a transverse wall.
