Reinforced concrete structure is the main building structure, and formwork engineering is an important part in concrete moulding. The reproducible thermoplastic composite plastic materials reinforced by bamboo fiber can fully take advantage of the bamboo fiber's virtues of high strength and the thermoplastic plastic's virtues of water resistance, corrosion resistance, abrasion resistance and being recycled, while can overcome the disadvantage that bamboo can easily absorb water and become mild...
