Compression molding of semi-concentrated fiber suspensions: Flow and fiber orientation
(Publ by ASME, 1993)The focus of this paper is compression molding of semi-concentrated fiber suspensions. During compression molding a premeasured amount of raw material (charge) is placed between two halves of a die. The die is then closed ...
