The ESA has partnered with European firms CompPair, CSEM, and Com&Sens to bring self-healing materials to spacecraft. To achieve this new goal, the ESA aims to modify an existing self-healing carbon fibre product that was developed by one of its partners, creating it ready for utilize on spacecraft.
A New Era Of Spacecraft Might Be In The Making
The ESA Project Cassandra (Composite Autonomous SenSing AnD RepAir) is preparing to usher in a new era for spacecraft. This project, which is a part of the ESA’s Future Innovation Research in Space Transportation (FIRST!) initiative, will introduce healing elements to future spacecraft.
At its foundation, this project aims to solve an issue that plagues spacecraft built utilizing composite materials like carbon fibre. This issue lies with these materials, as they are sensitive to damage despite being materials that are strong, lightweight, and resistant to corrosion.
In 2020, CompPair, a Swiss company, started developing its HealTech technology, a self-healing composite material. To initiate the healing process, this technology relies on heat, which activates the healing agent inside the composite material.
But how exactly can this technology be utilized in spacecrafts? The ESA has already tested prototypes of CompPair’s HealTech technology fitted with a network of fibre-optic sensors for possible utilize in spacecraft.
In the event of damage to the self-healing composite material while in space, the fibre-optic sensors can pinpoint the damage. After identifying the damage, the material undergoes a heating process through integrated 3D-printed aluminium grids.
This raises the composite material’s temperature to 140°C, enabling the self-healing process to commence. According to the ESA, the tests it conducted on the HealTech prototypes for utilize on spacecraft focutilized on “the material’s damage monitoring, homogenous heating and self-repair abilities.”
How Will The ESA Put This Self Healing Material To Use On Future Spacecrafts?
While the ESA is testing prototypes of this material for utilize, it still has a long way to go before it is put to real-world usage. The ESA declares that the next phase of testing will aim to see how this material will fare when put to utilize in a larger shape, like a cryogenic fuel tank.
How these self-healing materials perform in this test will determine whether or not they’ll be utilized in future spacecraft. Regarding its potential, this material might be able to curb waste production during
