Abstract
Systems and methods for 4D printing of composites are described herein. A composite layer arrangement is obtained for forming a composite laminate having a substantially flat profile. A plurality of composite layers are deposited according to the composite layer arrangement to form the composite laminate. The composite laminate is activated to produce a curved composite structure.
Claims18
A method for four-dimensional printing of a composite structure, the method comprising:
- obtaining a composite layer arrangement for forming a composite laminate having a substantially flat profile;
- depositing a plurality of composite layers according to the composite layer arrangement to form the composite laminate, each one of the plurality of composite layers comprising longitudinal fibers having a longitudinal direction;
- and
- activating the composite laminate to produce the composite structure comprising at least one curvature.

A system for four-dimensional printing of a composite structure, the system comprising:
- an automated fiber placement machine comprising:
- a fiber placement head for depositing a plurality of composite layers onto a surface;
- a control unit comprising at least one processing unit and a non-transitory computer-readable memory having stored thereon program instructions executable by the at least one processing unit for:
- obtaining a composite layer arrangement for forming a composite laminate having a substantially flat profile;
- and
- causing the fiber placement head to deposit the plurality of composite layers according to the composite layer arrangement to form the composite laminate, each one of the plurality of composite layers comprising longitudinal fibers having a longitudinal direction;
- and
- an activation unit for activating the composite laminate to produce the composite structure comprising at least one curvature.
