Instaclave Technologies Inc.

Instaclave Technologies Inc. is a California research, development and manufacturing company working in material science. Founded by John Steven Calder, it applies its Differential Pressure Assisted Resin Transfer (DPART) process to make carbon fiber parts, with commercial and military aerospace as a main market. The company states that DPART parts made with the same carbon fiber materials and resins are about 30% stronger than parts made by standard VARTM, so a part can use less material and weigh less. For UAVs, drones and electric air taxis that means more range.

Products and research

• Instaclave Aviation: DPART carbon fiber upgrade and replacement components for military and commercial aircraft
• Instaclave Aerospace: inflatable carbon fiber research for large structures in space, made without molds, vacuum or autoclave curing
• Large Scale Array Extruder, a system proposed to DARPA for deploying carbon fiber tube structures in space
• Licensing of the DPART process and of DPART compatible resins and materials

Partners

The company lists Lawrence Berkeley National Laboratory as a research and development partner and states that the Department of Energy approved its CRADA contracts and development plans and provided funding. In a November 2025 release it said it would begin manufacturing aerospace carbon fiber parts in the first quarter of 2026.
