Hexcel, a manufacturer of aluminum honeycomb sheet, became well known for its branded skis, using this same advanced material. Sporting uses may be every bit as demanding as aerospace needs. Particularly in cycling, materials may be loaded more highly than in aerospace use, the risk of possible failure being seen as more acceptable than for ...

A typical later PSP was the M8 landing mat. A single piece weighed about 66 pounds (30 kg) and was 10 ft (3.0 m) long by 15 in (0.38 m) wide. The hole pattern for the sheet was produced to allow easier transportation by aircraft, since it weighed about two-thirds as much.
