Advanced Thermoplastic Composite Manufacturing by In-Situ Consolidation: A Review

IN-SITU FABRICATION PROCESS OF AL- TIC COMPOSITE BY SLAG

The new in situ method for AI-TiC composite fabrication has been carried out. In this method, fabrication of AI-TiC composite by simultaneous introduction of titanium oxide and carbon into aluminum melt was investigated.. Under the process conditions, titanium and carbon reaction results in titanium carbide whiskers. The salt containing keriolite (Na3AIF6), titanium oxide (TiO2) and graphite us...

Advanced Manufacturing Technologies: Literature Review

With the emphasis on reducing costs and increasing efficiency, a record number of companies are embarking on different forms of advance manufacturing technologies (AMT). AMT are broadly defined by many authors (small and chen, Sheppard and stock) as “ an automated production system of people, machines and tools for the planning and control of the production process, including the procurement of...

Novel Thermoplastic Polyimide Composite Materials

Press Forming a 0 / 90 Cross - Ply Advanced Thermoplastic Composite Using the Double - Dome Benchmark Geometry

A pre-consolidated thermoplastic advanced composite cross-ply sheet comprised of two uniaxial plies orientated at 0/90 has been thermoformed using tooling based on the double-dome bench-mark geometry. Mitigation of wrinkling was achieved using springs to apply tension to the forming sheet rather than using a friction-based blank-holder. The shear angle across the surface of the formed geometry ...

A Method of Forming Composite Structures Using In Situ-Formed Liquid Crystal Polymer Fibers in a Thermoplastic Matrix

A new high speed and potentially economical method of creating a composite material and structures therefrom is tested. The method consists of spinning composite fibers from a melt blend of a thermoplastic with a liquid crystal polymer (LCP). Discontinuous fibrils of the LCP are formed in situ during the spinning process. These composite fibers are aligned and placed in a mold and heated to mel...
