Flexural Behavior of Full-Scale Composite Structural Insulated Floor Panels

Effects of elevated temperature on the shear response of PET and PUR foams used in composite sandwich panels

“…The high potential of those solutions for structural applications, as an alternative to more traditional materials, stems from their lightness, together with relatively high strength-and stiffness-to-weight ratios and improved durability [6][7][8]. These properties are frequently achieved through the use of polymeric materials, such as fibre reinforced polymer (FRP) facings, providing bending stiffness, and lightweight polymeric foam cores, providing shear stiffness.…”

Failure mode prediction for composite structural insulated panels with MgO board facings

“…CSIP's facings are made of composite materials which make it considerably stronger, immune to biological corrosion and more durable to weather conditions. Such desirable improvements, in comparison to traditional SIPs, make CSIPs a very attractive alternative with a broader field of applications [16][17][18][19][20][21]. Increased strength of this type of sandwich makes it a viable option even in bridge structures [22][23][24].…”

Thermoplastic composite structural insulated panels (CSIPs) for modular panelized construction

“…Also, SIPs have poor penetration resistance against low and high velocity impacts. Earlier studies [3] on OSB-based SIPs revealed that the SIPs failed at the low impact velocity of 50 J when impacted with blunt object impactor. This 50 J impact energy typically represented events such as a tool drop or a furniture drop on the structural fl oor panel.…”

“…The facesheets of CSIPs comprise E-glass fi bers impregnated with polypropylene (PP) matrix. Greater strength and stiffness, better impact resistance, and weight savings of approximately 180% (per unit area basis) can be obtained by using the proposed panels [3].…”

“…Structural design and characterization of the proposed CSIPs can be obtained from Refs [3] and [4]. Section 12.2 describes the brief history of panelized construction, also covering the manufacture of traditional SIPs and the cost benefi ts of using precast SIPs in panelized construction.…”
