Geometrical exploration will start one of the most simple geometry, Vault, with half-circle section. While maintaining same radius would ease of production, the shape is structurally not optimized, so that the vault will take bending moment. The span is 6m. The lengths is adjustable as needed.
Biodegradable plastic is made of corn, degradable within 20 days into soil under specific condition. The production of Biodegradable plastic has been started in 2004 in PRD, China, currently mainly used for food container with vacuum forming processing.
Vacuum forming is widely used is packaging industry, while some of large scale components can be applied for architectural use, such as Poly carbonate top light dome, etc. The maximum production could be up to 1.2 x 2.4m with 3-5mm thickness. Most of thermoplastics could be applied theoretically, although its rigidity and fl exibility are varied depends on types of plastics, such as PS, PET, PVC, etc. The merit of vacuum forming is once its mould has been done, vacuum forming process is relatively easy, could be self-fabricated.
