This experimental study addresses the progressive crushing responses of laminated corrugated beams fabricated using Newport NB321/7781 E-glass prepreg material. Stacking sequences of [0]_n and [±45]_n, where n=4,8 and 12 have been used. The progressive crushing behavior has been studied at quasi-static rates and at selected dynamic loading rates. The test data indicates that the peak load levels increase with load rate, while the sustained crushing load decreases. [0]_n surpass [±45]_n in terms of energy absorbing capability at various loading rates by at least 30%. The failure modes in [0]_n beams was observed to be rate sensitive with the number of fronds and frond fragmentation changing with test speed.
