Composite characteristics modified process parameters

A clear improvement of the mechanical characteristics with regard to tensile and impact characteristics of multilayer web reiirforced PLA composites was achieved by using modified process parameters (compression moulding technique CP-2). In comparison to the processing technique CP-1 a pre-drying step was inserted (2 hr at 105°C) and the compression molding time in the hot press was reduced to 5 min. The cooling of the composites occurred in a cold press for 5 min at 25°C.
