...LC Dickinson; GL Farley; MK Hinders A translaminar-reinforced (TLR) composite is an otherwise two-dimensional laminate with through-thickness or Z -direction fibrous reinforcement across the lamina. Only small amounts (less than 5% volume) of TLR are necessary to substantially improve compression...

...H Nayeb-Hashemi; Y Yang Finite element analyses were performed to evaluate the residual stresses developed during the fabrication process of the Nextel 440/A1-6061 composite. The purpose of the analyses was to find the effect of fiber orientation and fiber spacing on processing-induced thermal...

...JC Seferis A fundamental problem of advanced airplane composite systems is the lack of understanding of the aging process and how it affects the material properties associated with degradation. The concept of Equivalent Property Time (EPT) was established and can be used to understand degradation...

... that time, further studies have focused on evaluating the growth of the surface layer. The composition and features of this layer were found to change as the aging temperature changed. Microcracks and small voids initiated and advanced inward at all temperatures. Visible oxidation at the surface occurred...

...MV Hosur; CRL Murthy; TS Ramurthy Carbon fiber reinforced plastic (CFRP) composite laminates are susceptible for multiple delaminations, which reduce the compressive strength significantly even when the impact load is insufficient to cause visible damage. The post-impact compression test is used...
