SAMPE 2013 Long Beach new product showcase
The SAMPE 2013 trade show (May 6-9, in Long Beach, Calif.) was the venue for introductions of a large number of new composite materials, technologies and manufacturing processes. Here's the HPC editorial staff's compilation of what was on display.

Commercial trucking: Streamlining the Big Box
Glass fiber-reinforced thermoplastics help commercial trucking industry optimize weight, fuel and cost savings.

Rapid layup: New 3-D preform technology
Hook-and-loop fasteners speed layup of carbon, aramid, glass and hybrid fabrics while improving composites’ mechanical performance.

Small wind gets big
Massive growth, complex blade designs reopen challenging market in wind energy niche.

Leading-edge erosion: Materials solutions
Depending on operating conditions, erosion of rotor blade leading edges can affect wind turbine energy generation efficiency as soon as two years after installation.
