Mitsubishi Plastics have announced the starts of full-scale production of a new grade of pitchbased carbon fibre
The new product (DIALEAD K13312) has been developed with very good tensile modulus (rigidity), as well as a tensile strength of 3,200 MPa (Mega Pascal), approximately 20% higher than the Company’s conventional products. K13312 also has improved workability (handling capability).
There are currently two main classifications of carbon fibre; polyacrylonitrile (PAN)-based and pitch-based. Since pitch-based carbon fibre has excellent tensile modulus (rigidity) and heat conductivity, it is possible to produce carbon-fibre-reinforced plastics (CFRP) with the near zero coefficient of thermal expansion.
This new product is currently being used for the Tokyo metropolitan expressway, where major reinforcement work is being carried out. The application opportunities are expected to expand in the future, including the reinforcement of aging bridges and buildings. Improved workability increases processing speed, lowers customers’ costs and opens additional opportunities for “DIALEAD K13312” to applied to not only carbon fibre sheets for reinforcement but also products in the fields of energy and sports.
