La. Ruhala et Rs. Engel, A study of the impact performance of fiber reinforced composite laminated plates due to various relative fiber contents and densities, J THERM COM, 12(3), 1999, pp. 227-239
Fiber-reinforced composite laminated plates (FRPs) have many potential appl
ications in the area of automotive structural crashworthiness. Among these,
an FRP may be used as a side door liner to absorb and dissipate energy dur
ing a side impact, thus allowing less door intrusion into the passenger com
partment, potentially reducing occupant injury. As a first step in the desi
gn of such a plate, the authors have studied the effects of relative fiber
content on the impact properties of laminated composite plates with a parti
cular emphasis on the damage mode-that is, delamination, matrix cracking, a
nd fiber breakage. E-glass fiber/epoxy plates with fiber weight percents ra
nging from 50 to 80 percent were studied at impact energies ranging from 5J
to 40J.
