In-situ emulsion polymerization method on the PMMA/SBA-15 composite
关键字：Polymethyl methacrylate; SBA-15; composite material; emulsion polymerization
PMMA/SBA-15 composites were prepared from three different in-situ emulsion polymerization methods, that is, batch, semi-continuous and prior-immersion, which differed from incorporation of monomer methyl methacrylate and mesoporous SBA-15. The stability&n...

Formation and structures study of PHBV/chitosan composite ultrafine fibers prepared by emulsion electrospinning
关键字：PHBV; chitosan; phase inversion; emulsion; electrospinning
PHBV and chitosan are two natural materials of biocompatibility and renewability. However, they cannot be prepared by electrospinning simultaneously, because they have no co-solvent. In this work, chitosan/H2O/acetic acid solution (W) was d...

Structural design of variable-stiffness laminates
关键字：variable-stiffness composite; fiber path; structural optimization;minimum compliance design
Variable-stiffness composite changes its stiffness properties by fiber orientation angles varying along the length of laminates. The influence of central cutout and different fiber paths on the stiffness is investigated. An optimal criterio...
