This kind of epoxy resin for carbon fiber has very good performance,not only can resist UV resistance,but also high toughness,which is much better than the resin used in fiberglass,so you don’t need to worry.In the carbon fiber distribution structure,there are 70% unidirectional and 30% off axis,and they are alternating,so they can resist breaking、cracking and dropping.If you can meet the requirements in the test shafts,just follow this structure.The delivery time is limited by the molds.Each mold can only make one shaft per day.I think we need to make 3 more molds,4 molds in total,100 shafts can be made in 25 working days,plus 5 days for assembly,and one week for mold manufacturing.The delivery time is 7 weeks.Anymore,last time we did one mold cost was $176.47,now we do 3 more molds at a preferential price of $160.00/pcs,a total of $480.00.If you are sure to place an order,pls send the mold fee($480.00) and 50% payment for shafts(50*$56.78=$2839.00),a total of $3319.00 to our my account(LAND & OCEAN(USA)INC.).If any questions,pls let me know,thanks~
