Advances in the synthesis and scalable manufacturing of single-walled carbon nanotubes
(SWCNTs) remain critical to realizing many important commercial applications. Here we …

Achieving extreme dynamic performance in nanofibrous materials requires synergistic
exploitation of intrinsic nanofiber properties and inter-fiber interactions. Regardless of the …

Thermal transport properties play a critical role in the performance of lightweight foams used
as shock-absorbing layers in helmets, sports gear, and electronic packaging. We report …

In this study, the impact response of polymer composites containing a random distribution of
carbon nanotubes (CNTs) has been investigated by considering energy profile diagrams …

The deformation and impact energy absorption properties of ultrathin polymeric microlattices
were investigated as a function of density, size and positional eccentricity of the trusses …

Creating lightweight architected foams as strong and stiff as their bulk constituent material
has been a long-standing effort. Typically, the strength, stiffness, and energy dissipation …

Protective applications in extreme environments demand materials with superior modulus,
strength, and specific energy absorption (SEA) at lightweight. They must also have the ability …

Background Helmet systems most commonly experience oblique blunt impacts which cause
simultaneous linear and rotational accelerations. The ability to attenuate both linear and …

Vertically aligned carbon nanotube (VACNT) arrays or “forests” behave mechanically as
foams when compressed, exhibiting a characteristic nonlinear stress–strain response …

In this paper we describe experiments and a continuum phase transition model for the
compression of carbon nanotube (CNT) forests. Our model is inspired by the observation of …
