Machining composites presents unique challenges compared to metals. Reinforcement fibers are abrasive, shortening tool life. The plastic matrix carries away little heat, unlike metal chips, and overheating can melt the matrix. Composites can delaminate, and burrs and fibers show on poorly drilled holes or poorly trimmed edges. Other challenges include machining or drilling laminate stacks […]

Faced with aggressive deadlines to deliver specialized satellite parts, San Diego’s Vanguard Composites Group started a search. They needed to reduce the time required to machine thick composite sandwich panels before assembly. The large flat panels, made in a variety of measured thicknesses, serve as support structures for satellite antenna reflectors. Vanguard is one of […]

Matching the drill tool to the job can save thousands of man-hours and millions of dollars. For six decades, “you get what you pay for” has been the marketing mantra for manufacturers and suppliers of composite products who argue that, despite their historically high initial cost, composites are the superior product in terms of overall […]
