I have formulated a shear-lag model for calculating the variation of stress along carbon nanohorns (CNHs), which are conical shaped wrapped carbon sheets, embedded in an epoxy matrix under axial loading.  I found that the stress distribution along the length of CNHs depends on the cone angle of these structures and maximum normal axial stress has a smaller value in CNHs compared to a carbon nanotube (CNT) with same cross-section as of the CNH's tip.  Furthermore, I read an article stating that synthesis of CNHs are easier compared to CNTs.  However, the only article I could find which has studied the CNH-reinforced nanocomposites is

 Low-Dimensional Carbon Nanomaterials: Synthesis, Properties, and Applications

NANOSHEL makes more than 50 types of products, among which the main products are nanotubes, SWCNT´s, MWCNT´s, nanoparticles,. These products are widely used in the fields such as textile industry, ceramics, chemical fiber, plastics, coatings, cosmetics, rubber, electrical and electronic equipments, electric power generation and boiler and so on.

Dr. John Hart from MIT is giving a carbon nanotube (CNT) tutorial at the International Symposoum on Nanomanufacturing (ISNM) at MIT on November 1st, Wednesday. Please see the following if you are interested.
