Abstract

Vacuum-based insulation system has been widely used in daily lives to maintain low temperature for storage purposes. While this method of insulation is widely available and easy to make, it has one major shortcoming in the form of it’s fragility. The system cannot be exposed to concussive shocks since it could break the outer shell of the containment and removes the vaccuum, causing a containment breach. If this happen, the system will rapidly lose insulation and the contents inside is no longer stored in low-temperature environment. Ice could be used to preserve the low temperature environment, but not for long. Pykrete is an ice-composite material made from a mixture of water and cellulose-based reinforce material (either wood or paper) with very high resistance against concussive shocks and very resistant against melting compared to the regular ice. Pykrete has a potential to be used as protective insulation material, with the aim to keep the temperature inside low even in containment breach situation much longer than regular ice. This research has shown that pykrete, in general has a much longer cooling duration compared with regular ice (roughly up to 2 to 3 hours more) as well as better mechanical properties based from the calculations performed on it’s theoretical tensile strength, depending on the contents of it’s reinforce material. However, this also comes with a cost of slightly lower cooling temperature compared to regular ice (1 to 2 degrees Celcius higher). This properties makes pykrete well-suited for low-cost insulative protection for cold storage application, concept of application can be in the form of spaced armor protection.
