The present work
concentrates on the development of 3-D hemispherical biaxial weft-knitted (BWK)
thermoset composites. The objective is to improve the quality of the 3-D
composites with BWK preform. Two kinds of the 3-D hemispherical BWK composites
with the flat surfaced and 3-D dome shaped biaxial weft-knitted preforms were
produced by hand lay-up method. The quantitative analysis of wrinkles was done
by measuring the locking angles between the fiber bundles in the composites. Small
numbers of wrinkle heights (1 height/1 cm) were observed on the flange surface
of the 3-D hemispherical BWK composite with the dome shaped preform compared to
the 3-D hemispherical BWK composite with the flat surfaced preform (10
heights/1 cm).
