MANUFACTURING METHOD FOR PRODUCT FROM COMPOSITE MATERIAL USING HEAT-SHRINKING FILM

摘要

The present invention relates to a manufacturing method of a composite material product using a heat shrinking film. According to one aspect of the present invention, a manufacturing method of a composite material product using a heat shrinking film is disclosed, which comprises the steps of: (a) preparing a heartwood form having the same appearance with the form for manufacturing a target product; (b) forming the original form of a product while laminating a composite material on the outside of the heartwood form and applying a liquid resin; (c) covering the outside of the original form of the product with a heat shrinking film; (d) pressurizing the original form of the product by heat shrinkage of the heat shrinking film as providing the original form of the product covered with the heat shrinking film with a temperature condition wherein the temperature is above heat shrinkage of the heat shrinking film; and (e) obtaining a final product laminated and hardened with the composite material as removing the heat shrinking film or removing the heat shrinking film and the heartwood form after passing the time required for hardening the liquid resin.
