| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系 === 84 === In the resin transfer molding (RTM) process , the fiber
preform can be made in either 2-D or 3-D forms . In order to
reduce the cost of production, 2-D fiber proform is preferred
whenever it is adequate . For a stiffened panel made of 2-D
fiber preform , delamination usually occurs in the joint of the
stiffener to the panel as subjected to impact , and propagates
rapidly to the rest of areas . This study is to investigate the
effect of the through thickness Kevlar fiber stitching of the
fiber preforms on the integrity of the stiffened panel . Several
type of stitching patterns were tested to evaluate their
influences . It is concluded that through thickness fiber
stitching could provide better resistance to crack propagation
as subjected to impact and have higher toughness .
