CFRP use expanded in Porsche 911 GT3
Bigger than its predecessor, but with only a slight increase in mass thanks to light weight body panels.

Although the seventh generation of the Porsche 911 GT3 has an increased front track of 1.9 inches compared with its predecessor, the curb weight of the 2022 model is still a light 3,157 pounds, and only slightly heavier (4 pounds) than the previous generation (3,153 pounds). That weight increase would have been much greater if the company had not made more extensive use of carbon fiber-reinforced plastics (CFRP) in the vehicle.
The hood, rear wing, and fixed wing are all CFRP. A carbon fiber roof is optional, as are carbon fiber mirror caps. Another weight-saving option are full carbon seats: Compared to the standard seats in the 911 GT3, the composite seats represent a 26-pound mass reduction.
The 2022 Porsche 911 GT3, which is to become available in the U.S. in the fall, is fitted with a 502-horse power, 4.0-liter engine that propels the car from 0 to 60 miles per hour in 3.2 seconds. Top speed: 197 miles per hour.
A look at the process by which precursor becomes carbon fiber through a careful (and mostly proprietary) manipulation of temperature and tension.
The structural properties of composite materials are derived primarily from the fiber reinforcement. Fiber types, their manufacture, their uses and the end-market applications in which they find most use are described.
Oven-cured, vacuum-bagged prepregs show promise in production primary structures.
