PROBLEM TO BE SOLVED: To provide a base material that is an environmental-friendly material, that can be provided as a lighter-weight material by reducing weight, that is excellent in humidity resistance and strength, and that may be applied not only to a vehicle interior material but also to various interior materials in various industrial fields such as railway, aircraft, and construction industrial fields.SOLUTION: The present invention relates to an environmental-friendly lightweight base material and the base material is manufactured by: adding a moisture-curable isocyanate or epoxy for complementing properties of a vehicle interior material base material having a sandwich structure and containing natural fibers susceptible to a high-temperature humidity environment; complementing a degraded physical property by entry of moisture into the natural fibers to improve humidity resistance and strength of a natural fiber reinforced layer; and continuously manufacturing the base material using heat lamination on a thermoplastic foamed sheet core material layer. The base material is manufactured by the present invention.
【課題】 環境にやさしい素材であり、重量の低減による軽量化が可能であると共に、耐湿性と強度に優れ、自動車内装材だけでなく、鉄道、航空機及び建築用内装材といった多様な産業分野に応用され得る基材を提供する。【解決手段】 自動車用内装材用環境にやさしい軽量基材に関し、高温多湿な環境に弱い天然繊維を含むサンドイッチ構造の自動車内装材用基材の性能補完のために水分硬化型イソシアネート又はエポキシを添加し、天然繊維の水分の侵入による物性の低下を補完して天然繊維補強層の耐湿性と強度を改善し、熱可塑性発泡シート芯材層に熱ラミネーションを用いて連続的に基材が製造されることを特徴とする。本発明により製造された基材は、【選択図】 図１
