The size reduction of waste polymers and composite materials has become an important subject in the field of waste reclamation. And these energy consumption by size reduction of waste polymer and composites as GFRP (Glass Fibre Reinforced Plastics) are very large for the reason of their high strength and plastical properties.
Therefore this investigation has been carried out as a part of assuring energy saving on pulverizing. Then, in this investigation, stress (load)-strain (displacement) curves on the 4 kinds of fracture process (tensile, compressive, flexural and shearing) are measured 4 kinds of resins and GFRP, and next fracture surface energies in individual cases are calculated from their curves and compared them.
The results obtained are as follows
(1) Fracture surface energy on shearing load is least in 4 kinds of load.
(2) Fracture energy of GFRP are exceedingly large, it is owning to reinforcement of glass fibre and interlaminer delamination.
