چکیده
This work aims to shape a hollow cylinder with geopolymer and an additive manufacturing process (3D printing) without organic additives. The formulation of composite using only mineral parts is proposed the parameters 3D printing were optimized. mechanical properties, microstructure, adhesion layers material analysed compared literature. results showed that could be printed addition small ratios wollastonite, glass fibers, or non-reactive aluminosilicate by modifying speed. stacking exhibited good between them, avoiding so-called “cold joints” effect, fibers are flow-oriented during process. Some cylinders successfully flexural strength 15 MPa.

3D-printing of lightweight cellular composites.
A new epoxy-based ink is reported, which enables 3D printing of lightweight cellular composites with controlled alignment of multiscale, high-aspectratio fiber reinforcement to create hierarchical structures inspired by balsa wood. Young's modulus values up to 10 times higher than existing commercially available 3D-printed polymers are attainable, while comparable strength values are maintained.
متن کاملRotational 3D printing of damage-tolerant composites with programmable mechanics
Natural composites exhibit exceptional mechanical performance that often arises from complex fiber arrangements within continuous matrices. Inspired by these natural systems, we developed a rotational 3D printing method that enables spatially controlled orientation of short fibers in polymer matrices solely by varying the nozzle rotation speed relative to the printing speed. Using this method, ...
متن کاملMulti-shape active composites by 3D printing of digital shape memory polymers
Recent research using 3D printing to create active structures has added an exciting new dimension to 3D printing technology. After being printed, these active, often composite, materials can change their shape over time; this has been termed as 4D printing. In this paper, we demonstrate the design and manufacture of active composites that can take multiple shapes, depending on the environmental...
متن کاملSynthesis and Characterization of Novel Epoxy Geopolymer Hybrid Composites
The preparation and the characterization of novel geopolymer-based hybrid composites are reported. These materials have been prepared through an innovative synthetic approach, based on a co-reticulation in mild conditions of commercial epoxy based organic resins and a metakaolin-based geopolymer inorganic matrix. This synthetic strategy allows the obtainment of a homogeneous dispersion of the o...
متن کاملThe Brittleness and Chemical Stability of Optimized Geopolymer Composites
Geopolymers are known as high strength and durable construction materials but have a brittle fracture. In practice, this results in a sudden collapse at ultimate load, without any chance of preventing the breakdown of parts or of withstanding the stress for some time. Glass fiber usage as a total anisotropic shape acting as a compact structure component should hinder the fracture mechanism. The...
