As a result, materials researchers, engineers, and scientists are constantly working to improve existing materials or develop whole new ones.
From ordinary products to complex specialist applications, modern composite materials are a substantial part of the artificial materials business.

Construction Channel Problems for Building Materials and Workers The ultra-soft soil has extreme low strength, so it is impossible for the workers to walk on it and it is very hard to transport the building materials on it.
So the float bridge can remain stable and offer enough channel for workers and transportation of building materials..
The float bridge constructed with foam plastic plates can provide a steady platform for the transportation of construction materials and workers.

But that the curing behaviors for many advanced composites have to complete at higher temperatures will generate residual stress in the final moulding of the materials, resulting in bending, which will thus bring some difficulties for the assembly of composite materials, even lower materials strength and fracture toughness, make the matrix crack and take off layer, impacting the application safety of advanced composite materials[2,3].

In the field of material science and structural engingeering, the size differs between laboratory specimen and pratical constructions is inevitable.
Rearch interests in the size effect is a very old topic, in fact older than the mechanics of materials itself.
Materials and specimens For each strength grade of concrete and reinforcred concrete specimens is with the same water-cement ratio and the same cement-sand ratio.

Wood composite materials were created as an alternative to solid wood and their specific properties enabled the use of wood materials in fields where solid wood was used ineffectively or could not be used at all.
Moreover, the production of wood composite materials enables valuation of wood residue [1,2].
