A steam-thermolysis process to recover carbon fibers from CFRP waste

The Carbon Fiber Reinforced Plastic (CFRP) it's a high performance materials and made from 70% resin thermoset matrix. Recycling CFRP wastes currently offers interesting economic and environmental perspectives. There are two main recycling process enable for carbon fiber recovery : pyrolysis and steam thermolysis.

Pyrolisis is a based on the organix matrix thermal degradation, and steam thermolysis is a process thermochemical using superheated steam at environmental pressure to degrade the organic matrix composite and recover the carbon fiber.

For recycling carbon fiber was conducted in bench scale reactor and previous made composite sample are treated by the steam thermolysis process so as to reclaim carbon fiber. The composite sample will be analyze with thermogravimetric analyzer.

The following comparison between pyrolysis and steam thermolysis against removal resin and tensile strength is :

Pyrolisis
steam thermolysis
Removal resin
Tensile strength
Removal resin
Tensile strength
97.97%
69.04%
99.52%
82.56%

Based on thermogravic analyzer, the organic matrix more degraded with steam thermolysis than pyrolisis, and the activation energy for steam thermolysis lower than with pyrolisis.

Bio-based building block to reduce the environmental footprint of composite materials

Epicirol is biobased Epichlorohydrin (ECH) produce from glycerol and glycerol is renewable feedstock and by product from biodiesel and oleochemical productions. The ECH based on glycerol offers environmental advantages compared to the ECH based on from propylene.

The advantages of epicerol is 100% renewable carbon, 61% global warming potential reduction, 57% less energy consumption. The advantages for process production epicerol is lower water , lower chlorine input, minimal water effluent and minimal chlorinated by product.

The best solution to managing corrosion with non-metallics in mining Industry

DERAKANE® Epoxy Vinyl Ester Resins for Mineral Recovery Process Equipment in the Mining Industry. Premium high-performance thermoset resins for fiberglass reinforced plastic (FRP) are:
Corrosion and Temperature Resistant
Flame Retardant
High Strength-to-Weight Ratios
Low Cost Compared to Exotic Metal Alloys
Good Electrical Insulation Properties
Smooth One-Piece-Mold Interior Surfaces
Practically Maintenance Free

The process chemicals and the general environment found in the refining of mineral recovery operations are among the most corrosive of any industry. Traditional materials of construction, such as carbon steel, stainless steel, other exotic alloys, and masonry, often break down shortly after being placed in service.

Some application deraken for mining industries include :
Chemical Storage Tanks
Chutes and Elevators
Cell Covers
Cooling Towers
Duct, Fans, and Scrubbers
Dust Control Systems
Electrolytic Cells, Copper Cells, and Manganese Cells
Electrostatic Precipitators
Electrowinning Cells
Extractors
Process Tanks, etc

No single FRP resin can handle every kind of corrosion problem. Ashland has the largest variety of premium corrosion resistant resins in the industry. Ashland Inc. is the largest supplier of corrosion-resistant resins for fabricating reinforced plastics. Reinforced plastic composites are used for mineral recovery operations in many types of chemical environments. Each environment requires a specific type of resin to handle the corrosive conditions.

Sustainable design in composites

It is essential, for the future not just for the economy but for the whole of mankind, that sustainable eco-friendly manufacturing methods are developed. Cradle to cradle it is the framework seeks to create production techniques there are not just efficient but are essentially waste free.

In cradle to cradle production all material inputs and outputs are seen either as technical or biological nutrients. Technical nutrients can be recycled or reused with no loss of quality and biological nutrients composted or consumed. By contrast cradle to grave refers to a company taking responsibility for the disposal of goods it has produced, but not necessarily putting products' constituent components back into service.

Approach the composite design based on cradle to cradle framework:
Eliminate toxic material
Have assembly in mind separate biological and technical nutrients.

The conclusions of conferences with eco- design and recycling program is to encourage us to turn to the material , design , and proper process , in order to reduce the waste generated from the production process. By selecting the material , design , and the right process , environment is expected to be maintained.
