Prototyping and manufacturing by additive fabrication
 Additive fabrication (AF) technology, such as laser sintering (LS) and fused deposition modeling (FDM), encompasses a wide range of applications. The earliest was rapid prototyping to support design, concept modeling, fit/function testing, and pattern making without the need to construct expensive tooling for prototypes and test articles. Manufacturers also are using AF to produce jigs, fixtures, drill guides, and other manufacturing and assembly tools.

Compression after impact testing
During the late 1960s and most of the 1970s, the composites industry was absorbing the impact of what was then the recent introduction of carbon fiber. The resulting composites exhibited both high strength-to-weight and high stiffness-to-weight ratios. And while it was known that composites reinforced with this new
