摘要

By means of polarizing optical microscopy (POM)

deformation behavior of four kinds of fibers

i.e. ultra highmolecular weight polyethylene (UHMW-PE) fiber

polyvinyl alcohol (PVA) fiber

polyethylene terephthalate (PET) fiber

and wholly aromatic (p-hydroxybenzoic acid/2-hydroxy-6-naphthoic acid) copolyester [P(HBA/HNA)]/PET (ACPET blend)fiber

in axial compression

axial impacting

and bending was observed. In compression

kink bands formed at an angle of55～60° to the fiber axis in 10-times-drawn UHMW-PE fiber

75～80° in 40-times-drawn sample

80°in PVA fiber

and 90°in the ACPET blend fiber.In impacting and bending

band angles of UHMW-PE

PVA and PET fibers are nearly the same as those formed in compression

indicating that slip systems do not change.For any of the four kinds of fiber

band spacing exhibits great differences in compression

in impacting

and in bending

which may be attributed to the differences in the degrees of strain or stress concentration.
