Abstract

PURPOSE:To improve separability after concrete is cured when it is stuck to a form material, and reduce the residual ash content even at incineration disposal time by arranging a thermoplastic resin layer on a surface of a reinforcing fiber layer, forming a reinforcing fiber unexposed surface on this surface, and setting a coefficient of linear expansion not more than a specific value. CONSTITUTION:A polypropylene resin sheet is heated and press-fitted to glass fiber nonwoven fabric from both surfaces, and is cooled, and a fiber reinforced thermoplastic resin sheet is obtained. In thas case, a coefficient of linear expansion of this sheet is set not more than 7X10<-5>cm/cm/ deg.C. A thickness of the fiber reinforced thermoplastic resin sheet is set not more than 1mm. This fiber reinforced thermoplastic resin sheet is pressurized and adhered to a single surface of thick plywood by using an adhesive by putting the polypropylene resin sheet side inside, and a form material is formed. Therefore, separability of concrete after the concrete is cured is improved, and the residual ash content can be reduced even at incineration disposal time.

2. Description of the Related Art Generally, the main form of concrete pouring formwork is plywood using tropical timber, which has been faced with when constructing concrete buildings such as buildings and condominiums. It is widely used as a mold in which concrete is poured between two molds, the concrete mold is hardened, and then the molds are removed.

The mold made of plywood, which has been used conventionally, has a poor removability of concrete after curing and concrete is apt to adhere to the surface of the mold.
Although it is limited to ~ 3 times and is generally disposed of after this number of times of use, the use of tropical timber, which is a raw material, is pointed out as a representative example of destroying tropical rainforests, and reduction of tropical timber consumption is required. Therefore, molds made of other materials, that is, molds made of steel, aluminum, fiber reinforced plastic, etc. are also used, but all of them have problems of weight, durability, mold manufacturing cost, etc. Therefore, it cannot be said that the product is satisfactory.
