(a) Bulk density and (b) Young's modulus of composites as a function of the fibre content and the nature of starch and fibres. The welding time is 0.70 s, pressure is 15 MPa with the highest amplitude. “CB”, “CTMP” and “Amylo” refer to chemical pulp, mechanical pulp and amylose-extender starch, respectively.
