Forged composite

From Wikipedia, the free encyclopedia

Forged composite is a type of carbon fiber SMC material composed of small pieces of carbon fiber composite material that are pressed into shape as the resin cures. This is in contrast to most carbon fiber composites, which are made of larger continuous layers that are 'laid up' one at a time, often manually. Forged composite allows for a higher range of shapes to be formed with precision, relative to traditional carbon fiber. It was originally developed jointly between Lamborghini, Callaway Golf Company, and the Lamborghini Lab. [1][2][3][4] It was unveiled at the 2010 Paris Motor Show in a Lamborghini concept car.[5] The United States trademark for forged composite was filed on July 13, 2010, in the category Toys and Sporting Goods Products by Callaway Golf,[6] while the trademark for Forged Composites was registered in 2018 in the automotive category by Lamborghini.[7]

Forged composite contains higher fiber volume content, which combined with higher variation in strand orientation, increases the average strength and reduce variability over standard carbon fiber.[8] The material is one-third as dense as metal titanium but stronger,[9] and consists of chopped carbon fiber tows that are sandwiched between two layers of filmed resin.[10] It uses about 500,000 intertwined fibers per square inch.[5] The fibers contain intertwined and folded sheets of carbon atoms aligned with the length of the fiber, and the intertwining improved the fiber strength. The result is improved load carrying capacity as measured in bending per unit of mass.[11] Due to its chopped nature, it can be molded into much more complex geometries than traditional carbon fiber composites, and is suitable to make three-dimensional parts and parts which feature complex details such as thickness transitions, holes, compound curvature, etc.

Lamborghini uses forged composite for structural components, and interior trim and seats of its cars, the latter contributing to its winning of the JEC Composites Innovation Award for Automotive Interiors in 2016, due to the material's unique appearance.[12] Union Binding Company entered a partnership with the Lamborghini ACSL in order to develop a snowboard binding using forged composite technology. In 2014, the all-forged composite "Union FC" snowboard binding was launched and subsequently won the 2014 ISPO Product of the Year Award.[13]

Callaway claims the use of forged composite results in an average about 8 yards (7 m) greater distance per drive relative to traditional carbon fiber when used in its driving golf clubs. The material can contribute to reduced weight in vehicles.

Forged Composite Look[edit]

The 2010 debut of the Sesto Elemento showcased the new marbled look of carbon fiber obtained from using forged composite, which has since become a highly desirable aesthetic for carbon fiber parts, in particular in automotive and consumer goods.[14] Unlike the traditional woven carbon fiber look, the forged composite look is marbled and always unique due to the random nature of the material.

Since the launch of forged composite technology, several aesthetic applications making use of the coveted forged look have followed, including:
