Description
まず、本発明のハイブリッド木質コア集成材の表裏層を形成する集成板(30)を製造する。集成板(30)の製造は、ラミナ乾燥、長さ接合及び縦接合、接着、及び仕上げ工程の順に実施する。
次に、コアで使用される合板(40,41)を製造する。この段階で使用される合板の利用樹種は、カラマツ、リギダマツ、アカマツ、ユリ、白樺、栗、松、ヒノキ、杉などの国産材と、ラジアータパイン、ユーカリトップス、メランティ、MLH(mixed local hardwood)、ポプラ、ベトナム産アカシア、KERUINGを含む南洋材の混合種などであり、使用される接着剤には、フェノール、メラミン、尿素及びイソシアネート系などの熱硬化性樹脂、PVAc、PVA、EVA、PUR、エポキシ樹脂などの熱可塑性樹脂、並びにホットメルト系とゴム系接着剤が含まれる。
前述したように、製造された集成板(30)を表層と裏層にして、その間に前記のように製造されたコア層を接着剤で接合して、ハイブリッド木質コア集成材を製造する。図2a〜図2dは、第1の実施形態に係るハイブリッド木質コア集成材を示す図であり、図2aは、コア層として最上階の繊維方向が集成板(30)と平行な3つの合板(40)が積層されて行われたものであり、図2bは、最上階の繊維方向が集成板(30)と交差する3つの合板(41)が積層されてなるものであり、図2cは、コア層としての中間には、最上階の繊維方向が集成板(30)と平行な合板(40)と、その上下側に最上階の繊維方向が集成板(30)と交差される合板(41)が結合されてなるものであり、図2dは、コア層としての中間には最上階の繊維方向が集成板(30)と交差する合板(41)と、その上下側に最上階の繊維方向が集成板(30)と平行な合板(40)が結合されてなるものである。
