Description
本発明は、積層造形によるポリマー材料、特に熱硬化性材料の部品製造の一般的な分野に関し、より詳細には、航空機用ターボジェットのようなターボ機械の音響壁面コーティングの製造に関するものであるが、これに限定されるものではない。
したがって、本発明は、低周波数から高周波数まで広がる広い範囲の周波数に亘って、航空機のターボジェットによって発生する騒音を大幅に低減することができる、新しい材料を形成する方法を、その目的として有する。この方法に由来する音響コーティングは、流体の流れに接触するターボ機械の壁、より詳細にはファンケーシングに取り付けられることが意図されている。
フィラメントの三次元足場を形成するために、犠牲材料を基板表面上に堆積させること、
前記三次元足場の少なくとも一部に熱硬化性材料を浸透させること、
前記熱硬化性材料を固化させて固化材料を形成すること、および、
前記犠牲材料を前記固化材料から除去して、相互接続されたマイクロチャネルの整列化されたアレイを形成すること、を含み、
前記相互接続されたマイクロチャネルの整列化されたアレイに音響特性を付与し、したがって前記音響コーティングを形成することを特徴とし、前記三次元足場を重ね合わせた層によって形成する前記フィラメントは、フィラメントの所与の層について、前記入射音響波の方向Acに対して、前記層によって形成される平面内に第1の所定の角度θを形成する方向に配向される。
