Polyester (PET) is an organic material, a polymer plastic that is commonly used as a fiber for cloth production, or a matrix for glass fibers in Fiberglass
In situ Production
Polyesters are polymers (chains) that contain ester groups in their repeating structure. The most common form is polyethylene terephthalate (PET).
- Polyethylene terephthalate is produced from ethylene glycol and dimethyl terephthalate (DMT) (C6H4(CO2CH3)2) or terephthalic acid.
- Ethylene glycol is a primary chemical feedstock and is very likely to be produced on Mars fairly soon.
Properties
Embodied energy: about 125 MJ/kg.
Density: 1370 kg/m3
Melting point: 115–135 °C
Strength: 2,5 MPa (360 psi)
