This article examines material economies of carbon fibre as a prosthetic form of masculinity. The paper advances three main arguments. Firstly, carbon fibre can be a site in which disability is overcome, an act of overcoming that is affected through masculinized technology. Secondly, carbon fibre can be a homosocial surface; that is, carbon fibre becomes both a surface extension of the self and a third-party mediator in homosocial relationships, a surface that facilitates intimacy between men in ways that devalue femininity in both male and female bodies. Carbon fibre surfaces are material extensions of subjectivity, and carbon fibre surfaces are vectors of the cultural economies of masculine competition. Thirdly, the article gives an account of Oscar Pistorius as an example of the masculinization of carbon fibre, and the associated binding of a psychic attitude of misogyny and power to a form of violent and competitive masculine subjectivity. The paper unpacks the affects, economies and surfaces of “carbon fibre masculinity” and discusses Pistorius’ use of carbon fibre, homosociality and misogyny as forms of protest masculinity through which he unconsciously attempted to recuperate his gendered identity from emasculating discourses of disability.
