摘要： Apparatus for producing bent multi-sided pultruded fibre reinforced plastic reinforcement bar for concrete (commonly known as FRP rebar) comprises multiple resin wetting stages to simultaneously resin impregnate multiple bundles of fibreglass rovings continuously drawn through the resin wetting stages, multiple spiral winding stages arranged to spiral wind warps around the multiple wet rovings, and multiple rotating multi-sided former frames for continuously winding thereon the multiple wet rovings and holding the multiple rovings while curing. A related method is also claimed.

摘要： A system (15) for manufacturing a reinforcing element (1) for reinforced concrete comprises a feeder (16) of a reinforcing fiber bundle (2) along a pultrusion path (4), an impregnating device (17) which impregnates the reinforcing fiber bundle (2) with a liquid thermoplastic polymeric resin (6) to obtain an impregnated fiber bundle (2), a forming channel (8) through which the impregnated fiber bundle (2) is conducted, a solidification device (19) of the composite thread (9) forming a solidified thermoplastic fiber-reinforced bar (11), a pulling device (20) which holds the reinforcing fiber bundle (2) taut along the pultrusion path (4), a winder (21) which winds the solidified bar (11) to form a coil (14), a provisional bending device (22) which bends the composite thread (9) not yet solidified or heats the solidified bar (11) to soften it, bends the heated bar (11) and then cools the bar (11) to solidify it again, so as to confer a continuous provisional curvature to the solidified bar (11) in the direction of the subsequent winding in the coil (14).

摘要： A composite structural component comprises an elongate member made of a polymer matrix composite material. The elongate member comprises a main portion extending along an axis A and an end portion with an inner surface extending from the main portion to an open end of the member. The composite structural component also comprises an end fitting forming a mechanical joint with the end portion, the end fitting comprising an internal portion positioned captive within the elongate member in contact with the inner surface of the end portion; an external portion positioned in contact with an outer surface of the end portion; and an adjustable fastener extending axially between the internal and external portions to clamp the end portion between the internal and external portions. The inner surface of the end portion in contact with the internal portion extends towards the axis A at an increasing angle to the axis A.

摘要： The present invention relates to a jack stand. The jack stand includes a base. A post, including composite material, extends from the base. The jack stand also includes a top for topping the post and for engaging with a load. Advantageously, the post may be lightweight (typically less than 12 kg) enabling the jack stand to be conveniently moved by a single person without exposing the person to significant risk of injury. The jack stand may be moved as a whole, or in parts.

摘要： The plastic structural article includes an elongated tubular shell having opposed end sections, a middle section there between and an interior cavity. The interior cavity has a foam core situated therein. The foam core comprises steam expandable polymer beads which when expanded substantially fill the interior cavity. The bead and shell are of a similar plastic composition enabling the articles to be reground and recycled. An apparatus for forming the articles and an associated method of manufacture are also disclosed. A thermal management system includes a panel having a periphery, and a skin having a thermal bond to an in-situ foam core. The panel has a thermal transmittance u-value ranging from 0.1 to 0.17 W/m2° C.
