To verify the state of matrix degradation, a pin-loaded mechanical test was applied on composite test pieces heat treated at various temperatures.
Pins are commonly used to join members of mechanical mechanisms.
Frank Downey, vice-president and general manager of A.M. & F's Pinspotter Division, said, that the patent application on the mechanical pin boy go back before 1900, and the A.M. &.
They can be things such as mounting holes (mechanical pins), nonconnecting copper etch objects, design outlines, dimensions, and areas.
The connection is designed as a mechanical pin-type fastener with a general purpose polyester matrix FRP.
A mechanical pinned joint in the CFRP laminates such as [0/±45/90]3S, [90/±45/0]3S, [0/±45/90]2S and [90/±45/0]2s is loaded statically and cyclically to finally obtain the critical condition for fatigue.
An algorithm of quantitative analysis of two basic contributions to the stabilization of martensite – atomic reordering ("chemical" stabilization component) and pinning of interfaces ("mechanical" contribution) – has been developed.
Advanced hybrid joints, which incorporate a specially designed array of macro-scale pins that provide mechanical interlocking reinforcement, have been developed in order to address the challenges associated with joining fibre reinforced composites to metals.
This work is aimed at providing a new joining technology for C/SiC composites and investigating the influence of drilling holes, hole distribution (including ratios of edge distance to diameter (E/D), width to diameter (W/D) and hole distance to diameter (H/D)) and the number of applied pins on the mechanical properties of C/SiC substrates and joints.
Static contacts are due to a combination of mechanical pinning and static friction, and a smaller whisker tip diameter will presumably allow the whisker to make static contacts with smaller surface features.
