  1. a) 지지부로서 폴리프로필렌을 기초로한 판 또는 직물의 본래 평평한 형성물을 180° 내지 220℃의 온도까지 가열하고,
    b) 평평한 형성물 또는 성형부품의 형태인 예열되지 않은 포움플라스틱층과 가열된 형성물을 상부와 하부에 주형기구가 형성되어 있는 압축기내에 놓고,
    c) 지지부 및 포움플라스틱층을 압력하에서 동시에 다층의 성형부품으로 만들고 서로 강한 결합력으로 결합시키는,
    폴리프로필렌을 기초로한 지지부와 포움플라스틱층으로 이루어진 다층의 성형부품을 제조하기 위한 방법에 있어서, 탄성중합체-포움플라스틱을 포움플라스틱층에 사용하고 20 내지 120바아의 압력으로 변형시키는 것을 특징으로 하는 다층의 성형부품을 제조하기 위한 방법.
