The glass-reinforced laminated composite is widely used in place of conventional structural materials. The glass fiber composites demonstrate outstanding strength in the uniaxial direction. The effect of carbon nanotube reinforcement percentage on the flexural strength of glass-reinforced polymer composites is investigated in this article. The flexural strength of the final laminates has been found to improve by reinforcing the Carbon nanotube. The small incorporation of MWCNT improves the flexural strength up to 51.3%. The 1.0 wt.% MWCNT reinforcement into GFRP shows the 51.3% improvement into flexural strength in comparison to GFRP composites. MWCNTs plays a prominent role to enhance the mechanical features of the developed samples. The SEM image is used to examine the nature and mechanics of failure. This study highlights the effect of carbon-based nanomaterial on the glass fiber reinforced epoxy composites.

Pneumatic delivery system is a popular system during 19th & 20th century where there was internet to send emails. These systems were used to send files from one department to other department in the office environment. Later these were slowly replaced by fax and email. Now-a-days these are being widely used in hospitals to deliver blood samples or drugs through capsule from one block to other block of the hospital to save time since blood samples and drugs weigh very less. Above being the case, a system was developed where a capsule containing blood samples or drugs of minimum 5kg of weight can be carried using less number of air compressors by creating a smart path. Till now there were systems which were designed for apartments and industries for transportation of products from one location to another location, but the developed system can be implemented in hospitals for drug delivery from one place to other place. The capsules can be built using suction pipes to reduce the cost of the system. Cost of the system can be further greatly reduced by using PVC or acrylic sheets. The system can be made more effective by using smart path which is specially designed to reduce traffic and time delay. The developed system allows the reuse and storage of compressed air in the pipes, so that less number of compressors are being used. The system also allows a unique method of finding the location of the drug in the whole system by Radio-frequency identification (RFID) tags. Finally, the developed system is very useful in hospitals for transporting drug by reducing the traffic and time delay. Further, the system can be developed such a way that it can be used to deliver the couriers in a faster rate to save time and the cost to deliver product can also be greatly reduced.
