A surrogate multilayered material and manufacturing method thereof includes a first fiber reinforced layer, the first reinforced layer including a crosslinked polymer and fibers, and a second fiber reinforced layer, the second reinforced layer including the crosslinked polymer and the fibers. A foam layer is disposed between the first and second fiber reinforced layers. Opposite faces of the foam layer are in direct contact with the first fiber reinforced layer and the second fiber reinforced layer. The foam layer has a compressive strength of about 3.5 to about 4.5 MPa, when measured as per ASTM-D-1621-73, and a shear strength of 1.50 to about 2.15 MPa, when measured as per ASTM-C-273.

A peristaltic pump head includes a housing assembly adapted for mounting to a drive mechanism, a roller assembly arranged with the housing assembly and a flexible conduit extending through the housing assembly and engageable by the roller assembly to impel fluid therethrough. The roller assembly and the flexible conduit are removable from the housing assembly without disconnecting the entire housing assembly from the drive mechanism. The roller assembly can include an axially extending drive shaft, a roller control body fixedly mounted to the drive shaft, at least a first end plate rotatably mounted about the drive shaft, and at least a first roller arm pivotably mounted to the first end plate. The flexible conduit can include a length of hollow tubing made of an elastomeric material, and at least one overmolded end fitting made of a rigid polymeric material and fused to an end of the hollow tubing.

A BOP packer, including a body disposed about a longitudinal axis and adapted to be compressed upon energization of the packer, and an insert having a form symmetrical about a plane parallel to the longitudinal axis, and embedded in the body with the body adhered to the insert to reduce extrusion of the body when the packer is energized. The insert includes an upper flange and a lower flange, each having a wedge-shaped configuration that expands from a relatively narrow portion at the end nearest the longitudinal axis, to a relatively wide portion at an opposite end, and a web element extending between the upper flange and the lower flange. The web element defines an elongated aperture through which a portion of the elastomeric body passes to help maintain the position of the metallic insert relative to the body, and to reduce shear forces between the insert and the body.

A method of manufacturing a component for a gas turbine engine includes applying a thermoplastic polymer sheet over a composite body for the component; applying a shield over part of the composite body, the shield terminating at an end which overlies the thermoplastic polymer sheet and defines an interface between shielded and unshielded regions of the component; and pressing the shield into the thermoplastic polymer sheet so that the thermoplastic polymer sheet deforms around the end of the shield, such that the exterior profile of the component at the interface between the shielded and unshielded regions is flush.
