| Abstract: | In R&D of U-foam pieces using plastic foam as core material;we found that the efficiency is poor,the material is easy to break and the obsolescent ratio is high when using direct heating of the core material.Thus the foam properties and the posibility of using its moistuse absorption property were studied,so it found that the foam core material can meet the reguirements when using the damp-heat molding process. |
