In some embodiments, the fibers F of the composite tape (CFT) of the first layer 418 extend in a first direction. In some embodiments, the fibers F of the composite tape (CFT) of the second layer 420 extend in the first direction. In some embodiments, the first direction extends along a longitudinal axis A-A of the roofing shingle in a “0 direction,” (i.e., along the length L), as shown in FIG. 12. In some embodiments, the configuration of the fibers of the composite tape (CFT) of the first layer 418 and the fibers of the composite tape (CFT) of the second layer 420 reduce buckling of the roofing shingle 410 in the 0 direction stiffens the roofing shingle 410 and reduces bending thereof from manual handling by a user.

In some embodiments, the roofing shingle 410 includes a flexural modulus that is higher than a flexural modulus of a roofing shingle in which the core layer 414 includes only the third layer 422 and does not include the first layer 418 and the second layer 420. In some embodiments, the roofing shingle 410 includes a coefficient of thermal expansion (CTE) that is lower than a coefficient of thermal expansion (CTE) of a roofing shingle in which the core layer 414 includes only the third layer 422 and does not include the first layer 418 and the second layer 420. In some embodiments, the composite tape (CFT) of the first layer 418 and the composite tape (CFT) of the second layer 420 is configured to adjust the flexural rigidity of the roofing shingle 410 is specific directions, tensile stiffness in specific directions, the coefficient of thermal expansion (CTE) in specific directions, and the time/stress/temperature properties of creep and shrinkage.

In some embodiments, the configuration of the fibers of the composite tape (CFT) of the first layer 418 extending in the first direction (0 direction) and the fibers of the composite tape (CFT) of the second layer 420 extending in the first direction (0 direction) reduce buckling of the roofing shingle 410. As used herein, the term “buckling” means to bend or a change in shape (deformation) under a load or force, and, with respect to the roofing shingle 410, a change in shape or mechanical stability under a load or force, including under thermal expansion loads.

In some embodiments, buckling of the roofing shingle 410 is reduced by reduction of the coefficient of thermal expansion (CTE) difference to reduce the thermal expansion load, resulting in the roofing shingle 410 less likely to reach a critical stress to buckling (ac) as calculated in the below formula:

$σ_{cr} = \frac{P_{cr}}{A} = S_{y} - {(\frac{S_{y}}{2 π} \frac{KL}{r})}^{2} (\frac{1}{E})$

In some embodiments, buckling of the roofing shingle 410 is reduced by decreasing the thickness of the third layer 422, but maintaining the radius of gyration (“r”, which is proportional to the flexural stiffness) will increase ac, and reduce buckling. In some embodiments, buckling of the roofing shingle 410 is reduced by increasing the radius of gyration (r).

In some embodiments, each of the first layer 418 and the second layer 420 has a coefficient of thermal expansion (CTE) of 5 micrometers per meter Kelvin (“μm/(m*K)”) to 15 μm/(m*K) and a modulus of 5 GPa to 20 GPa. In some embodiments, the third layer 422 has a coefficient of thermal expansion (CTE) of 300 μm/(m*K) to 400 μm/(m*K). In some embodiments, the effective coefficient of thermal expansion (CTE) of the roofing shingle 410 is 15 μm/(m*K) to 30 μm/(m*K).

In some embodiments, the effective radius of gyration (r) is increased by using a composite material in the core layer 414. In some embodiments, the radius of gyration for the roofing shingle 410 is calculated as:

$r = \sqrt{\frac{1}{A}}$

- where the area moment of inertia, I, is expressed as an equivalent based upon the composite materials. In some embodiments, E_compositeis the flexural modulus of the composite, and I_compositecan be calculated by assuming the rigidity of the two laminates is equivalent:

$I_{composite} = \frac{E_{polymer}}{E_{composite}} I_{polymer}$

In some embodiments, increasing the modulus of the composite by adding the CFT tape increases the radius of gyration (r), which reduces buckling.

Referring to FIGS. 10 and 11, as a non-limiting example of some embodiments, the roofing shingle 410 is brought to a temperature of 0° C. and heating up the roofing shingle 410 to above 60° C., a result of which no significant buckling occurs.

In some embodiments, the roofing shingle 410 has a wind resistance that conforms to standards under ASTM D3462 test standards. In some embodiments, the roofing shingle 410 includes a Class A rating when tested in accordance with ASTM D3462.

In some embodiments, the fibers F of the composite tape (CFT) of a first layer 418 extend in a second direction. In some embodiments, the fibers F of the composite tape (CFT) of the second layer 420 extend in the second direction. In some embodiments, the second direction extends transverse of the longitudinal axis A-A of the roofing shingle in a “90 direction,” (i.e., along the length W). In some embodiments, the configuration of the fibers of the composite tape (CFT) of the first layer 418 extending in the second direction and the fibers of the composite tape (CFT) of the second layer 420 extending in the second direction stiffens the roofing shingle 410 and reduces bending thereof from step loads.

In some embodiments of the invention, any of the disclosed roofing shingles or embossed membranes may be manufactured by various processes.

In some embodiments, a roll of material of the first layer, such as but not limited to a TPO roll, may be embossed at an embossing station. Thus, the following references to a TPO roll may refer to any or all of the disclosed first layers, which are disposed in or on a roll. At the embossing station, any process that provides an embossed or textured top surface may be used. At an adhesive application station, the adhesive, such as the butyl adhesive, may be applied to the embossed TPO. At the adhesive application station, the release liner may be adhered to the TPO roll by the adhesive, or the fiberglass-reinforced fire-retardant layer may be adhered to the embossed TPO roll by the adhesive.

The method may further include, at a second adhesive application station, application of the second adhesive to the fiberglass-reinforced fire-retardant layer. The method may also include application of the release liner, at the second adhesive application station.

In some embodiments, the first layer may be extruded directly on to the third layer—for example, onto the scrim layer, the fire-retardant layer, the shingle membrane layer, and/or the torchable membrane layer. Thus, in some embodiments, the embossed membrane or embossed shingle may omit an adhesive layer underneath the first layer.

In some embodiments, instead of embossing a TPO roll, a TPO extrusion line may form the TPO sheet, and the TPO sheet may be subsequently embossed at the embossing station.
