Engineering of advanced hybrid composites wherein aligned carbon nanotubes (CNTs) are integrated into polymer matrices of existing fibrous materials is growing in research labs around the world. Real concerns exist about possible exposures of researchers and laboratory personnel to CNTs, fibers (respirable and nanoscale) and nanoparticles during handling of nanomaterials, as well as during synt...

Objectives: This report explores the possibility of synthesizing enzyme–metal–organic framework (MOF) composites by ink-jet printing. Results: This study demonstrates that the direct synthesis of patterned enzyme–metal–organic framework (MOF) composites on various substrates including paper and polymeric films can be readily achieved by ink-jet printing bio-inks containing protein molecules, me...

Many diverse and important barriers, both real and perceived, inhibit automakers’ adoption of advanced composite materials. A strategy to produce an all-advanced-composite body-in-white (BIW) commercially could be the best method to overcome these barriers. This paper summarizes the ultralight, hybrid-electric “hypercar” concept, emphasizing why massoptimization is crucial to its design; summar...

Mechanical properties of hybrid braided composite rebars are evaluated and compared to theoretical predictions which account for specific processing parameters including yarn size, braiding machine setup, and fiber type. Using a combination of high modulus carbon (Thornel P-55S) and aramid (Kevlar 49) fibers bars have been produced of up to 10 mm diameter with a Young's modulus of 200 GPa, a bi...
