Aerospace Composites Manufacturing and Characterization

June 16, 2020

The mechanical properties and associated cost of a composite structure are strongly dependent on the technique used to manufacture it. ARIC offers a broad range of equipment for manufacturing composites, including an autoclave, hot presses, resin transfer molding facilities and high-temperature ovens. A range of additive manufacturing equipment is available for building parts in both plastics and metals. The Center also has a range of equipment that can be used to characterize the key physical properties of resins and the permeability of fabrics for use in both autoclave and out-of-autoclave manufacturing. The Center also has advanced non-destructive testing equipment for identifying and characterizing defects in composites.

 

  • Hot air autoclave (Scholz) – With a capability to manufacture composites panels with dimensions of up to 2 meters by 1 meter. The maximum temperature capability of the autoclave is 400o C and maximum pressure rating is 21 bar.

  • Small hot press (Meyer) – Platen size is 300 x 300 mm with a maximum temperature capability of 400o

  • Resin transfer molding press (Coexpair) – Platen size 1000 x 600 mm with a maximum temperature capability of 200o The maximum press capacity is 120 tonnes.
