Three-dimensional printing fiber reinforced hydrogel composites.
An additive manufacturing process that combines digital modeling and 3D printing was used to prepare fiber reinforced hydrogels in a single-step process. The composite materials were fabricated by selectively pattering a combination of alginate/acrylamide gel precursor solution and an epoxy based UV-curable adhesive (Emax 904 Gel-SC) with an extrusion printer. UV irradiation was used to cure th...
متن کاملThree-dimensional microvascular fiber-reinforced composites.
Living systems rely on pervasive vascular networks to enable a plurality of biological function in both soft and hard tissue. Extensive vasculature in composite structures, such as osseous tissue in bone and tracheary elements in trees, exemplify natural materials that are lightweight, high-strength, and capable of mass and energy transport. In contrast, synthetic composites possess high streng...
متن کاملProcessing of Carbon Fiber Reinforced Composites by Three Dimensional Photolithography
The reinforcement of photoresins with continuous carbon fibers is discussed in this paper. The processing was conducted in an automated desktop photolithography unit (ADPU) developed and built in-house. Continuous fibers were added in situ to the photoresin to obtain composite samples containing over 20 vol% of the fibers. The tensile strength of these composites improved by at least a factor o...
متن کاملThree-dimensional printing of continuous-fiber composites by in-nozzle impregnation
We have developed a method for the three-dimensional (3D) printing of continuous fiber-reinforced thermoplastics based on fused-deposition modeling. The technique enables direct 3D fabrication without the use of molds and may become the standard next-generation composite fabrication methodology. A thermoplastic filament and continuous fibers were separately supplied to the 3D printer and the fi...
متن کاملCarbon Fiber Reinforced Bismaleimide Composites
Bismaleimide (BMI) resins are developed very rapidly due to the demands of the defense and aerospace industries. They are cross-linked polymers which process like epoxy resins but have an upper use temperature of 230°C, compared to the epoxy upper use temperature of 175°C. Also due to the available intrinsic properties of BMI resins such as higher thermal stability and lower toxicity than those...
