• CFRP has already shown their lightweight potential

• Automation and series manufacturing is necessary for an ecological and

economical production

• The biggest potential savings are gained by reduction of process costs

Conclusions about NCF

• Significant cost savings during storage and curing process

– No need for tight climate controls during storage and downstream processes

– No need for expensive autoclave process to cure parts

• High grade of playability

– Individual carbon layers can shift to one another

• Super large and complicated shapes are possible

– No parts size restrictions due to autoclave sizes

• One step process from the carbon package to the fabric is possible

• High grade of flexible and fast fabric design changes

continuous weft insertion cut to length weft insertion - Cut & Lay

• raw material is endless fixed in PIN-

PIN transport- system, what

continuously moved to the knitting unit

• Glas, Aramid, Carbon, Basalt, …

• hybrid- structures possible

• medium to heavy grammage

• 3K up to 24 K (50K)

• raw material is cut to length and cutted tape-

sequences are fixed in a PIN- field- system, what

contineously moved to the knitting unit

• mainly to produce carbon fibre products

• lightweight to heavy grammage

• 3K up to 50K (60K)

• Less waste with a high output

high fabric quality

high output up to 4,8 m/min
