The piezoelectric ceramic sensor was fixed on Glass Fiber Reinforced Plastic (GFRP) composite civil materials, using the external paste method for damage detection test. effect of depth and number cracks surface GFRP specimen signal received by studied. time-domain graph energy based wavelet packet were drawn, combining active induction packet. It is found that greater degree specimens, smaller...

this work presents an experimental investigation of the influence of the six important machining parameters (tool nose radius, tool rake angle, feed rate, cutting speed, cutting environment (dry, wet and cooled) and depth of cut) on surface roughness & material removal rate in the machining unidirectional glass fiber reinforced plastics (ud-gfrp) composite using carbide (k10) cutting tool durin...

Glass/carbon fiber reinforced plastic (GFRP/CFRP) and hybrid components have attracted increasing attention in lightweight applications. However, residual stresses induced the manufacturing process of these can result warpage and, eventually, negatively affect mechanical performance composite structures. In present work, GFRP, CFRP, GFRP/steel CFRP/steel were manufactured through prepreg-press-...

Plantation softwood timber poles are associated with low natural durability, and it is also not clear what the effects of high humidity environment on long-term performance composite action integrity such a system. This paper presents durability study for proposed using (GFRP) glass fiber-reinforced polymer as confinement system wooden sourced from plantation timber. Radiata pine 6 m length wer...

The demand for Composites in the modern era have increased immensely due to its vast applications and superior properties over conventional materials. Glass Fibre Reinforced Plastic (GFRP) is one of economic alternative engineering materials high specific modulus elasticity, strength, good corrosion resistance, fatigue strength lightweight. Components made out from GFRP composites are usually n...

An automobile industry have an interest in replacement of conventional leaf spring with composite leaf spring to get better performance with less weight. This paper deals with by replacing the conventional leaf spring with composite leaf spring. The dimensions of an existing conventional steel leaf spring of a light commercial vehicle were taken to fabricate the special die which is further use...
