11/6/2020, · Shells of cycling ,helmets, are typically made of ,composite, materials like fiberglass or lightweight carbon fiber, or very hard plastics such as polycarbonate or ABS. And liners are usually about 20cm (0.8 inches) thick and made of two layers of foam: a soft, bouncy layer that absorbs small bashes and bumps and a stiff layer that permanently deforms to absorb very hard impacts.

Helmet, impact velocity ,experimental, data is analyzed and various factors that influence the impact velocity are studied. One of the main goals of this ,report, is to verify whether a tolerance of +/- 3 percent of mean velocity is feasible and will allow at least 95 percent of impacts to fall within the proposed impact velocity range. Statis­

Helmet,-to-,helmet, impacts are often glancing blows owing to the smooth rounded shape of the ,helmet,. This was recognized in both the design of the pendulum arm and initial selection of impact sites. Impacts to a wide variety of sites on ,helmets, revealed that hits high on the ,helmet,, or nearly tangential to the outer profile, tended to be very minor in terms of head accelerations.
