Static and fatigue data available in literature concerning carbon fiber reinforced composite laminates subjected tension-tension fatigue were re-elaborated in the framework of a two-parameter fatigue model explicitly accounting for the cyclic as well as the mean stress. The data were used to obtain the model parameters by best fitting procedures. A primitive statistical implementation of the mo...

In this study, compressive strength and contraction of Polymer Composite Laminates made of E-Glass / Carbon bi-woven fabric reinforced in Epoxy resin matrix has been evaluated experimentally. Composite laminates were fabricated using hand lay-up technique for different ply orientations of 0,30,45,60 and stacking sequence of (00/300/450/600)2S for 2 and 3 mm laminate thickness. The laminates wer...

Lithium metal batteries (LMB)-laminate-type full cells were prepared by combining a high-concentrated electrolytes lithium bis(fluorosulfonyl)imide (LiFSI)/ethylene carbonate (EC) and the 3-Dimensionally Ordered Macroporous (3DOM) Polyimide (PI) separator, cycle characteristics compared with cell using conventional polypropylene (PP) + polyethylene (PE) which is widely used in ion batteries. Th...

In this study, the effect of fiber orientations on natural frequencies hybrid composite laminate (HCGFRE) that is consisted sequential stacking plain woven carbon reinforced epoxy (CFRE) and glass (GFRE) fibers was investigated. A finite element approach carried out in order to determine laminate. Analyzes were performed using LS-DYNA® software. analysis, corresponding first three modes determi...

An innovative recycling process for thermoset composite laminates is proposed by thermo-mechanical disassembly and further compression molding of hybrid thermoformable plates. Due to the process, single cured plies are extracted from waste laminate. Subsequently re-lamination performed interposing thermoplastic films between reclaimed plies. Final consolidation carried out molding. In order sho...

UNLABELLED This pilot study compared impact strain at the core and root surfaces between two different post-core systems. MATERIALS AND METHODS The form of a bovine mandibular front tooth was modified to resemble that of a human maxillary incisor as a test specimen. A cast post and core (Metal PC) and composite resin and glass fiber-reinforced epoxy resin post (Fiber-Resin PC) system were tes...

Because of the socioeconomic status of the patients, direct resin composite laminate veneers were used to improve the esthetics of their maxillary and mandibular anterior teeth. Laminate veneers are restorations which are envisioned to correct existing abnormalities, esthetic deficiencies and discolorations This case report reflects the use of a innovative composite sculpting instrument ( OPTRA...

The objective of this study was to experimentally evaluate the fatigue limit 90° unidirectional carbon fiber reinforced plastic (CFRP) laminates. very high-cycle properties specimens were evaluated using ultrasonic and electromagnetic testing machines. Ultrasonic tests conducted obtain under giga-cycle regime. specimen geometry designed resonate at 20 kHz, consisted CFRP laminate a metal tab co...
