“…At 15 and 30wt% additions of coarse recyclate, the reductions were at least 26%. Bledzki and Goracy were the only ones to not find a significant reduction in flexural strength with the addition of larger particles [25]. When F2 fibrous recyclate from ERCOM was added, the flexural strength was unaffected at 15wt% substitution and was reduced by 17% at 30wt% substitution.…”

“…Two studies have investigated the recyclate use based on the classifications outlined in Table 2. Bledzki and Goracy, and Petterson and Nilsson added and substituted various combinations of P1, P2, and P2/F2 recyclate into BMCs and SMCs [25,26]. These and other studies, which were carried out using materials recycled in-house, are based on some type of impact grinding [5,6,23,24].…”

Recycling of thermoset molding compounds has been intermittently investigated for roughly the past 15 years. The use of sheet molding and bulk molding compounds has steadily increased over the same time period, but no closedloop recycling regime has been developed. First, a general discussion is made on the materials involved and some of their applications. The major recycling methodologies, energy recovery, chemical breakdown, thermal breakdown, and size reduction are all reviewed. Also, some of the new technologies being developed and areas where further work is needed are outlined.

“…The use of finely ground FRP in materials such as FRP, asphalt, engineered wood and polymer concrete has been researched in the past [10,17,[44][45][46]. Some studies have shown that using ground FRP as a filler in new polymeric composite materials can reduce mechanical performance of the new composite [47], while other studies have reported similar or even enhanced properties of polymeric composite materials as a result of incorporating mechanically recycled FRP waste. For example, it has been observed that substitution of up to 88% of the calcium carbonate filler in sheet molding compounds (SMCs) by fine particulate recycled FRP resulted in materials with comparable strength and stiffness [48].…”

A Critical Review of Research on Reuse of Mechanically Recycled FRP Production and End-of-Life Waste for Construction

For the last three decades, fiber reinforced polymer (FRP) composite materials have been widely used in major engineering industries. Managing FRP waste is becoming an important issue due to the growth in the production of FRP composite materials. In this article, the issue of FRP waste management is discussed and the commonly used methods for the handling of FRP waste are reviewed. One potentially viable use of FRP waste is in the partial replacement of fillers or aggregates in cementitious materials (particularly portland cement mortar and concrete). A number of important prior investigations performed on the use of FRP waste in concrete and mortar are reviewed. The results from most of those investigations suggest that FRP aggregates significantly reduce the strength of cementitious materials with little significant effect on durability. Recommendations for future research in this area are provided for producing stronger mortars and concretes incorporating FRP production and end-of-life waste.

An unsaturated polyester bulk molding compound is made containing unsaturated polyester sheet molding compound-recyclate added as reinforcement. Grinding techniques are used to obtain the sheet molding compoundrecyclate. The flexural strength and modulus of bulk molding compounds containing 0 and 100% recyclate used as the reinforcing material are compared. In both cases the flexural strength and modulus are found to be reduced. Micrographs of the recyclate-reinforced bulk molding compound fracture area show cracks that initiate and propagate along the recyclate-new resin matrix interface. The poor interfacial bonding is the major reason for the loss in the strength and modulus values.
