Materials Engineering
Callaway Golf receives a proprietary blend of prepreg material from Quantum Composites. Callaway processes the prepreg in-house and supplied 254mm x 254mm x 1.3mm panels of carbon fiber sheet molding compound (CFSMC) for characterizing. Tensile strength was analyzed by conducting tensile tests per ASTM D3039. Tensile coupons were cut to 254mm long by 25.4mm wide. Tabs were constructed from 1.6mm thick GFRP printed circuit board material. A commercial grade two part epoxy was used to bond the tabs to the CFSMC. Tensile results were inconclusive due to consistent fractures occurring outside the gauge lengths of the specimens.
Flexure strength was …

Aerospace Engineering
This paper gives an overview of the progress that has been made in the design build of the X-51. The X-51 is a composite scale replica of a P-51D fuselage integrated with a P-51H wing. Issues with the airframe as well as current action items are discussed, as well as findings so far in preliminary design.
