AI Technical Summary
Technical Problem
Existing methods for fabricating composite materials often result in high void content due to residual voids and void precursors, leading to structural defects and reduced mechanical integrity.
Method used
A method involving pre-heating substrates and porous networks to remove voids and void precursors, followed by embedding the porous network in the substrates under controlled pressure conditions, thereby reducing void formation and enhancing structural uniformity and integrity.
Benefits of technology
The method results in composite articles with significantly reduced void content and improved mechanical robustness, achieved under milder and less expensive conditions compared to traditional autoclave curing.
