Applied Research of Australia FRP Bolts – Manufacturing & Performance November 2011

Agenda AROA – An Introduction Our Research Programme & Findings

AROA – An Introduction Established as a research company in 1964 in South Australia Founded with support of Australian Government and the Department of Defense Key highlight – invented the technology that supports colour photocopiers and technology sold in mid-70s Early-80s AROA commenced research into composite materials and associated technology. Started to refine research into FRP reinforcement initially and then expanded into ground anchors. AROA Developed the first fully molded one piece three dimensional dowel – 1992 - installed by hand held machinery.

Our Research Programme Ground Support Solutions Potential Products Manufacturing Process Materials

Key Issues from Research Material Fibre Type Resin Composition Manufacturing Process Pultrusion of FRP Bolts Other Processes? Product Shear Strength Torsion/Torque Gloving & Encapsulation Thread Strength Research found that the key relationship was between the manufacturing process and the end product – materials could be adjusted to suit.

Product Research Finding the balance between tensile strength, torque and thread strength

The Gloving Challenge Having found the balance between tensile strength, torque and thread strength the challenge for the research programme was to address the common problem with FRP bolts of gloving. This research programme was conducted from 2003 - 2007
