The idea of strengthening a steel beam with carbon fiber is not new. Approaches have ranged from coating corroded steel i-beams with carbon fiber and epoxy to a patent by Boeing where carbon fiber ...

Laser powder bed fusion (LBPF), a 3D printing technique commonly used to make metal parts, creates large thermal gradients between areas hit by the laser and areas not being struck. This creates pools ...

Understanding how helical, curved beams operate — how their spiral cuts accommodate angular and parallel misalignment, axial motion, and system vibrations — is the key to knowing how they will perform ...

First, the payload requirements and problems faced by traditional multi-beam antenna are described. The user beam of the VHTS payload system mainly uses Ka-band multi-beam antenna for a large range of ...
