In one embodiment, an assembly fixture may include a base structure including a plurality of strands of a fiber-reinforced thermoplastic material comprising a thermoplastic embedded with a plurality of reinforcement fibers, wherein the plurality of reinforcement fibers is aligned within each strand of the plurality of strands, and wherein the base structure further comprises an anisotropic thermal expansion property based on an orientation of the plurality of reinforcement fibers within the base structure, The assembly fixture may further include a plurality of fastening structures coupled to the base structure, wherein the plurality of fastening structures is configured to fasten a plurality of components of a composite structure for assembly using a heated bonding process.

An additive manufacturing system is capable of extruding poly-fiber strand having a fiber core coated with a polymer with a high range of flexibility in positioning and orienting extruded fibers. Extruded fibers may be laid in a single direction, or may curve or turn to be laid in multiple directions. Structures of devices and components may be created using interconnected extruded strands having interstitial spaces between and around the strands. This structure may be infused with resin or polymer using a pressure or vacuum based infusion system. In this manner, durable polymeric objects can be created without requiring expensive molds. Other techniques are also possible, including varying the types of strands used in an object to create areas of the object that will preferentially twist or flex in certain ways or directions, as well as producing objects with zones having different types of resin or no resin.
