Fabrication and characterization of Fiber Reinforced plastic pipe using contrived split mold

Abstract

Fiber reinforced plastics (FRP) play a vital role in many engineering applications as an alternative to various heavy exotic materials. Such composite pipes are finding applications not only in construction industries, but also in the transportation of corrosive fluid. In FRP pipe composites, the matrix of polymer (unsaturated polyester resin) is reinforced with glass fibers (chopped strand mat and woven roving) in form of cloth like sheet layers. These pipes are manufactured through hand lay-up processes using contrived spilt mold method. The reinforcement sheet of FRP pipes prepared each require pallet size by hand and its round uniformly to form pipe with mandrel shaft seated on the working table and then inserted through fixed split mold and clamped with bolt and nuts. The amount of resin purring in contrived mold and closed cup clamped with fasteners for uniform embodiment of composite it rotates on lathe machine by fixed between tail and head stock. The produced products of FRP pipe needed post curing of 24 hours to remove and demolded from contrived split mold. This thesis mainly focuses on the mechanical properties of compressive strength, hardness and water absorption of chopped strand mat and woven roving fabricated FRP pipe. An experimental has been studied on the compressive strength of FRP pipe increased as the number of layers increased. The seven round of woven roving FRP pipe has best compressive strength value of 19.04 N/mm2 and chopped strand mat of seven round of FRP pipe has 15.93 N/mm2 . The hardness test result of 7 round layers of PWR pipe has high dens than other FRP pipe with Vickers hardness value of 64.93HV. The water absorption test of the chopped strand mat has better than woven roving pipe due to higher amount of resin matrix required to perform the product.
