Encontraron superconductividad en un material cerámico: el óxido de lantano, bario y cobre (LBCO), una perovskita basada en cupratos, a una temperatura crítica de
1986 saw the first industrial-scale production of continuous silicon carbide fibers (e.g., Nicalon). These fibers could be woven into fabrics and embedded in ceramic matrices to create . These CMCs were:
In June 1986, research from NASA detailed the creation of a "low-cobalt powder-metallurgy superalloy" for use in "highly-stressed jet-engine parts". By reducing the need for expensive and strategically important cobalt, this development made high-performance alloys more accessible.
Hasta ese momento, la superconductividad se consideraba un fenómeno frágil que solo existía a temperaturas extremadamente bajas, cercanas al cero absoluto ( ), utilizando costoso helio líquido. materiales fuertes 1986
The landscape of strong materials in 1986 was defined by a convergence of mature metallurgy and emergent chemistry. It was an era where the Nickel superalloy still ruled the engine, but Carbon Fiber began to rule the airframe. The industry was learning to trade the predictability of metals for the specific performance of composites. Looking back, 1986 stands as the end of the "Metallurgical Age" and the dawn of the "Composite Age," setting the trajectory for the high-performance, lightweight structures that define modern engineering.
Luces que giran en la fábrica, rostros que apagan su razón, pero en la hoja que dejo en blanco escribo la forma de mi canción.
The Airbus A310, flying extensively by 1986, utilized significant percentages of composite materials, and the McDonnell Douglas MD-11 program was utilizing advanced composites for tail sections. The primary matrix material in 1986 was epoxy, specifically toughened epoxies like Hexcel’s 8551-7, which sought to address the brittle failure modes of earlier generations. The strength of these materials was anisotropic, challenging engineers to design structures that leveraged the unidirectional strength of the fibers. In 1986, the debate regarding the "ductility gap"—the lack of plastic deformation in composites compared to metals—was a central topic in structural engineering journals. By reducing the need for expensive and strategically

The year 1986 stands as a watershed moment in the history of materials science. While engineers had spent decades refining steel and concrete, 1986 marked the sudden arrival of a new class of "super materials" that would redefine the limits of strength, conductivity, and durability. This year is best remembered for the high-temperature superconductivity revolution, but it also saw critical advancements in aerospace composites and ceramics that laid the groundwork for modern engineering.
No todos los hitos de 1986 fueron celebraciones. Los desastres del (causado por la falla de los anillos en O de caucho ante el frío) y de Chernóbil pusieron de manifiesto la importancia crítica de la integridad de los materiales bajo condiciones extremas. Estos eventos obligaron a la industria a replantear los protocolos de seguridad y la selección de materiales para entornos de alta presión y temperatura.
