Introduction:
I am supposed to design a boxing gloves, which are perfectly used by boxers for their purpose. A boxing gloves is a protective layer between punch and face, which stimulates the impact of a punch in it for damaging the face badly.
Design of boxing gloves
The boxing gloves which I used to made has following properties:
  • Compress-able
  • Comfortable
  • Fit-able
  • Anti-perspiration
  • Anti-bacterial
  • Bearable
  • Good grip
The composition of boxing gloves has several steps in which different stacking are used;

The first layer is the inner most layer which has to be in-contact with the skin. This layer should be absorbent, anti-bacterial, and tensionless. The layer would be of bamboo fiber which has an essential characteristic of environmental friendly.

The second layer should be bearable and water-repellent. It should be of cow hide leather which absorbs the stress and minimized the reaction of the impact.

The third layer should be more compactable, structural, water-repellent and compress-able. The layer should be of synthetic leather that cannot be damaged early and has to tolerate all the forces which boxer applies on it.

The last touch is of aesthetic performance it has good finishes, stretchable, long life, light weight and maintain the structure.

The limitations of the fabric are:
  • Max stress = 4.8263Mpa
  • Max speed= 16m/s
  • Weight= 110Kg
  • Momentum= 1760N/s
  • Compressive Strength= 48.26N
  • Young’s Modulus= 241.3
a) Momentum= mass x velocity
= 110 x 16
= 1760N/s

b) Strain= (lo – l) / lo
= (0.16 – 0.2) / 0.2
= -0.2 (negative signs shows the Compression effect in Gloves)

c) Young’s Modulus= Stress/Strain
= 48.26/0.2
= 241.3
