Abstract: Methods, apparatuses, and systems for making prepregs are disclosed. A method may include depositing a resin material onto a surface of a fiber bed and forming a number of discrete resin regions thereon. A distance between the resin regions may be measured to provide desired exposed portions of the surface to facilitate permeation of air through the exposed portions of the surface in a direction perpendicular to a plane of the fiber bed during a curing process of the prepreg.

Abstract: Methods, systems, and robots for multi-layer prepreg composite sheet layup. The robotic system may include a memory for storing a dataset including start and end point pairs of a mold of a 3D part that defines a layup sequence, a first robot or a first robot arm that is configured to conform a prepreg layer or sheet onto the mold of the 3D part, and a second robot or a second robot arm that is configured to hold or grasp the prepreg layer or sheet above the mold of the 3D part and stretch or relax the prepreg layer or sheet when the first robot or the first robot arm conforms the prepreg layer or sheet onto the mold. The robotic system may also include one or more processors connected to the first robot or the first robot arm and the second robot or the second robot arm.

Abstract: Methods, systems, and robots for multi-layer prepreg composite sheet layup. The method includes obtaining a dataset including start and end point pairs of a mold of the 3D part. The method includes generating a layup sequence based on the dataset and generating multiple trajectories for one or more movements of the first robot or the first robot arm based on the layup sequence. The method includes causing a second robot or a second robot art to hold or grasp the prepreg layer or sheet a threshold distance above the mold or the 3D part. The method includes causing the first robot or the first robot arm to place or conform the prepreg layer or sheet to the mold of the 3D part.
